[0022] Below, embodiments for carrying out the opening and closing device according to the present invention are illustrated with reference to the accompanying drawings. The embodiments illustrated below are intended to facilitate understanding of the present invention and are not intended to limit the present invention. The present invention can be modified or improved from the following embodiments without departing from the spirit thereof. Furthermore, in the accompanying drawings, the dimensions of each component may be exaggerated or reduced, and hatching may be omitted, for ease of understanding.

[0023] (First embodiment) Fig. 1 is a perspective view showing an example of an opening and closing device 1 according to the present embodiment. As shown in Fig. 1, the opening and closing device 1 includes a door unit 8 and a deadlock mechanism 3 that enables the deadlock of the door unit 8 to be electronically locked and unlocked.

[0024] The door unit 8 may be provided, for example, on a wall (such as a wall of a building) separating the indoors from the outdoors. A user of the opening and closing device 1 can move from the indoors to the outdoors or vice versa by opening and closing the door unit 8. In this embodiment, the door unit 8 may be, for example, a door provided at the entrance of a house. The door unit 8 includes two rectangular main surfaces 8A and 8B facing each other. The main surfaces 8A and 8B extend in a vertical direction (hereinafter referred to as the "second direction X") and a width direction (hereinafter referred to as the "first direction Y") perpendicular to the vertical direction, and have the same dimensions. The main surfaces 8A and 8B face each other in a thickness direction (hereinafter referred to as the "third direction Z") perpendicular to the first direction Y and the second direction X. The main surface 8B faces the indoor side of the building, and the main surface 8A faces the outdoors. Hereinafter, the side closer to the main surface 8A in the third direction Z may be referred to as the "main surface 8A side," and the side farther from the main surface 8A in the third direction Z may be referred to as the "outside." The door section 8 also includes two rectangular side surfaces 8C, 8C that face each other in the first direction Y. The two side surfaces 8C, 8C extend in the second direction X and the third direction Z and have the same dimensions. The two side surfaces 8C, 8C face each other in the first direction Y and include a side surface 8C on one side in the first direction Y (hereinafter, simply referred to as "side surface 8C on one side") and a side surface 8C on the other side in the width direction. The overall length of the side surfaces 8C, 8C in the third direction Z is shorter than the overall length of the main surfaces 8A, 8B in the first direction Y. That is, the door section 8 has a thin, flat, rectangular parallelepiped shape.

[0025] The deadlock mechanism 3 includes a deadlock 30. The deadlock 30 is provided on one side 8C of the door frame. In this embodiment, a deadlock 30 is provided on each of the upper side in the second direction X (hereinafter, sometimes simply referred to as the "upper side") and the lower side in the second direction X (hereinafter, sometimes simply referred to as the "lower side"), but a deadlock 30 may be provided on only one of the upper and lower sides. The deadlock mechanism 3 accommodates the two deadlocks 30 inside the door section 8 to be in an unlocked state, or protrudes the deadlocks 30 from the side 8C to be in a locked state, based on electronic or physical operations by the user. The above-mentioned electronic operations include locking and unlocking the deadlocks 30 using a remote control or a card key. Meanwhile, the above-mentioned physical operations include locking and unlocking the deadlocks 30 by manually turning the thumb turn 7 (described later) or turning a key inserted in the cylinder 9 (described later). The two deadlocks 30 can also operate synchronously.

[0026] The opening and closing device 1 further includes an outer handle 2, an inner handle 4, a battery box 5, two box locks 6, 6, two thumb turns 7, 7, two cylinders 9, 9, a latch bolt 1110, and the like.

[0027] The latch bolt 1110 is provided on one side surface 8C. When the door section 8 is in line with the wall, the latch bolt 1110 protrudes from the side surface 8C on one side and engages with the wall. This keeps the door section 8 closed. On the other hand, when the outer handle 2 or the inner handle 4 is operated, the latch bolt 1110 becomes rotatable, which releases the engagement between the latch bolt 1110 and the receiving portion (recess) of the door frame. As a result, the door section 8 can be opened. The latch bolt 1110 constitutes the latch lock 1000.

[0028] The outer handle 2 is attached to the main surface 8A of the door unit 8. More specifically, in the first direction Y, the outer handle 2 is attached near one side surface 8C. In this embodiment, when the deadlock mechanism 3 is in the unlocked state, if a user on the outside of the door unit 8 pulls the outer handle 2 toward the user, the latch bolt 1110 becomes rotatable as described above. This releases the engagement between the door unit 8 and the wall, causing the door unit 8 to rotate toward the user and open. Alternatively, when the deadlock mechanism 3 is in the unlocked state, a user on the outside of the door unit 8 may push the outer handle 2 away from the user, causing the door unit 8 to rotate away from the user and open. As will be described later, the outer handle 2 houses various electronic components (circuit boards, antennas, etc.) that constitute the deadlock mechanism 3. These electronic components enable the deadlock 30 of the door unit 8 to be electronically locked and unlocked.

[0029] The inner handle 4 is attached to the main surface 8B of the door unit 8. More specifically, in the first direction Y, the inner handle 4 is attached near one side surface 8C. In this embodiment, when the deadlock mechanism 3 is in the unlocked state, if a user who is indoors (inside) the door unit 8 pushes the inner handle 4 in the direction away from the user, the latch bolt 1110 becomes rotatable as described above. This releases the engagement between the door unit 8 and the wall, causing the door unit 8 to rotate in a direction away from the user and open. Note that when the deadlock mechanism 3 is in the unlocked state, a user who is inside the door unit 8 may pull the outer handle 2 toward the user, causing the door unit 8 to rotate in a direction toward the user and open.

[0030] The two thumb turns 7, 7 are provided on the upper and lower sides of the main surface 8B corresponding to the two deadlocks 30, 30. However, like the deadlock 30, the thumb turns 7 may be provided on only one of the upper and lower sides. Furthermore, in the first direction Y, the two thumb turns 7 are attached near one of the side surfaces 8C. The user may lock or unlock the upper deadlock 30 by turning the upper thumb turn 7, and lock or unlock the lower deadlock 30 by turning the lower thumb turn 7. The thumb turns 7 constitute the deadlock mechanism 3.

[0031] The two cylinders 9, 9 are provided on the upper and lower sides of the main surface 8A corresponding to the two deadlocks 30, 30. However, like the deadlock 30, the cylinders 9 may be provided on only one of the upper and lower sides. Furthermore, in the first direction Y, the two cylinders 9 are attached near one of the side surfaces 8C. In this embodiment, the cylinders 9 are housed inside the outer handle 2 and are exposed to the outside of the outer handle 2 by removing a cover member 25 (described later) from the outer handle 2. When a user inserts a key into the exposed cylinder 9 and turns it, the deadlock 30 is locked or unlocked. Alternatively, the upper deadlock 30 may be locked or unlocked by turning the upper cylinder 9, and the lower deadlock 30 may be locked or unlocked by turning the lower cylinder 9. The cylinders 9 constitute the deadlock mechanism 3.

[0032] The two box locks 6, 6 are provided on the upper and lower sides of the door section 8, corresponding to the two deadlocks 30, 30. However, like the deadlock 30, the box lock 6 may be provided on only one of the upper and lower sides. The box lock 6 is housed inside the door section 8 and includes various electronic components, including a motor. The electronic components of the box lock 6 cooperate with electronic components housed in the outer handle 2 to lock and unlock the deadlock 30. In other words, when the electronic components housed in the outer handle 2 are operated by a remote control or card key, the motor of the box lock 6 is operated accordingly, and the two deadlocks 30 may be electronically locked and unlocked in synchronization. The box lock 6 constitutes the deadlock mechanism 3.

[0033] The battery box 5 houses a battery inside as a power source. The battery box 5 is independent of the outer handle 2, inner handle 4, two locking boxes 6, 6, two thumb turns 7, 7, two cylinders 9, 9, and latch lock 1000, and is attached at any location on the door section 8. In the example of FIG. 1, the battery box 5 is attached at any location on the main surface 8B, and more specifically, is attached near the locking box 6 on the upper side. Wiring extends from the battery box 5, and power is supplied via this wiring to electronic components housed in the outer handle 2 and the locking box 6. In other words, the deadlock 30 is electronically locked and unlocked by the power supplied from the battery box 5. The battery box 5 constitutes the deadlock mechanism 3.

[0034] Next, the outer handle 2 will be described in more detail.

[0035] Figure 2 is a perspective view of the outer handle 2 as seen from the main surface 8A side. As shown in Figure 2, the outer handle 2 has a gently curved shape that is convex outward overall. The outer handle 2 includes a housing 20 and cover members 25 provided at both the upper and lower ends of the outer handle 2.

[0036] The housing 20 includes two fixing portions 24 and a grip portion 21. The two fixing portions 24 are located above and below the grip portion 21, and are fixed to the main surface 8A of the door portion 8. Specifically, each of the fixing portions 24 is provided with one or more mounting brackets 64 extending toward the main surface 8A, and these mounting brackets 64 fix the fixing portion 24 to the door portion 8. In this embodiment, two mounting brackets 64 are provided for each fixing portion 24, spaced apart in the second direction X. Furthermore, an elastic sheet member 26 made of rubber or the like is disposed on the surface of the fixing portion 24 facing the main surface 8A, and the fixing portion 24 is attached to the main surface 8A via this sheet member 26. By providing such a sheet member 26, the fixing portion 24 of the outer handle 2 can be tightly attached to the main surface 8A, thereby maintaining airtightness and preventing condensation and the like from entering the outer handle 2. The cylinder 9 is housed inside the fixed portion 24 .

[0037] Fig. 3 is an enlarged view of the fixing part 24 of the outer handle 2 as viewed from the main surface 8A side, and is an exploded view of the seat member 26. Fig. 4 is a view of part of the outer handle as viewed from the main surface 8A side with the seat member 26 removed, and is a view showing an example of the state in which the cover member 25 has been separated from the housing 20. As shown in Figs. 3 and 4, a circular cylinder hole 24CH is provided on the main surface 8A side of the fixing part 24 near the end in the second direction X. A rectangular cylinder hole 26CH is provided in the seat member 26 corresponding to this cylinder hole 24CH.

[0038] Furthermore, one or more boss portions 24B protruding toward the main surface 8A are provided near the cylinder holes 24CH on the main surface 8A side of the fixing portion 24. The number of boss portions 24B is not particularly limited, but is two in this embodiment. In this embodiment, the two boss portions 24B are provided at positions slightly away from the cylinder holes 24CH toward the grip portion 21, aligned in a straight line in the first direction Y, and located near both ends of the fixing portion 24. As shown in FIG. 3 , cuts 26im are provided in the sheet member 26 corresponding to the boss portions 24B. The number of cuts 26im is the same as the number of boss portions 24B. In this embodiment, the two cuts 26im are provided at positions slightly away from the cylinder holes 26CH toward the grip portion 21, aligned in a straight line in the first direction Y, and located near both ends of the sheet member 26.

[0039] Furthermore, a protrusion 24T protruding toward the main surface 8A is provided on the main surface 8A side of the fixed portion 24 at a position slightly away from the boss portion 24B toward the grip portion 21. Furthermore, an insertion hole 24iH penetrating the fixed portion 24 in the second direction X is formed in the fixed portion 24 of the housing 20. This insertion hole 24iH is located on the opposite side of the protrusion 24T from the grip portion 21. The protrusion 24T includes an inclined surface 24Tc extending from the insertion hole 24iH toward the grip portion 21, thereby increasing the length of protrusion toward the main surface 8A. One end (one end 72) of a strap member 70 made of an elastic material such as rubber engages with this protrusion 24T. Specifically, as shown in FIG. 4, a substantially square hole 72H is formed in the one end 72 of the strap member 70. When one end 72 of this strap member 70 is inserted from the insertion hole 24iH (upstream side) toward the protruding portion 24T (downstream side), the one end 72 is guided by the inclined surface 24Tc and gradually lifted toward the main surface 8A, and when the one end 72 eventually reaches the downstream side of the inclined surface 24Tc, the one end 72 drops to the opposite side (outside) from the main surface 8A in the third direction Z, and the hole 72H of the one end 72 fits into the protruding portion 24T. In this way, the one end 72 of the strap member 70 is engaged with the protruding portion 24T. That is, in this embodiment, the protrusion 24T is located downstream of the insertion hole 24iH in the insertion direction J (direction from the insertion hole 24iH toward the gripping portion 21) in which the strap member 70 is inserted into the insertion hole 24iH, and the inclined surface 24Tc of the protrusion 24T protrudes to a greater length in the insertion direction from the upstream side (the insertion hole 24iH side) toward the downstream side (the gripping portion 21 side).

[0040] Furthermore, the two mounting fixtures 64 described above are provided on the main surface 8A side of the fixed portion 24 on the grip portion 21 side with respect to the protruding portion 24T. Two through holes 26PH, which allow the mounting fixtures 64 to pass through, are formed at an interval in the sheet member 26 corresponding to the two mounting fixtures 64. Furthermore, as shown in Fig. 3, a slit 26SL is formed between the two through holes 26PH along the second direction X so that a part of a third member 63 of the operating portion 60, which will be described later, can move.

[0041] FIG. 5 is an enlarged view of the fixed portion 24 of the outer handle 2, viewed from the main surface 8A. As shown in FIG. 5, when the sheet member 26 is attached to the fixed portion 24, the cylinder holes 24CH and 26CH are connected to each other. A cylinder 9 is inserted into the connected cylinder holes 24CH and 26CH from the main surface 8A toward the outside, and the cylinder 9 is housed inside the fixed portion 24. For convenience, the cylinder 9 is not shown in FIGS. 2 to 5. When the sheet member 26 is attached to the fixed portion 24, as shown in FIG. 2, two mounting fixtures 64 pass through two through holes 26PH of the sheet member 26. Furthermore, as shown in FIG. 5, when the sheet member 26 is attached to the fixed portion 24, the portions of the sheet member 26 corresponding to the cutouts 26im are folded, and the folded portions 26a of the sheet member 26 may be fitted inside the boss portions 24B of the fixed portion 24. 5, the boss portion 24B of the fixing portion 24 is shown by a dashed line for convenience, since it is covered by the sheet member 26 and cannot be seen. In this way, the sheet member 26 is configured so that the folded portion 26a of the sheet member 26 can be fitted inside the boss portion 24B, thereby preventing the sheet member 26 from falling off the housing 20 (fixing portion 24). This makes it possible to prevent the sheet member 26 from shifting position when attaching the outer handle 2 to the door portion 8. However, the folded portion 26a of the sheet member 26 does not have to be fitted inside the boss portion 24B.

[0042] As described above, the cylinder 9 is housed inside the fixed part 24. As shown in Figures 1 and 2, the cylinder 9 is normally covered by a cover member 25 connected to the fixed part 24, and in a predetermined case, such as when a key is inserted into the cylinder 9, the cover member 25 is detached from the fixed part 24 to expose the cylinder 9. In other words, the cover member 25 is detachably attached to the housing 20, and detaching the cover member 25 makes it possible to insert a key into the cylinder 9 to lock or unlock the deadlock 30. The cover member 25 constitutes the deadlock mechanism 3.

[0043] As shown in FIG. 4 , the cover member 25 and the fixed portion 24 of the housing 20 are connected by a strap member 70. Specifically, as described above, one end 72 of the strap member 70 engages with the protruding portion 24T of the fixed portion 24. Meanwhile, the other end (other end 71) of the strap member 70 is formed in a T-shape. Furthermore, a fitting portion 25E into which the T-shaped other end 71 can fit is provided on the surface of the cover member 25 on the main surface 8A side. With this configuration, the other end 71 of the strap member 70 fits into the fitting portion 25E of the cover member 25, thereby attaching the strap member 70 to the cover member 25.

[0044] In this embodiment, the cover member 25 and the housing 20 are connected by the strap member 70, which prevents the cover member 25 from falling off the housing 20 when the cover member 25 is removed from the housing 20, and prevents the cover member 25 from being lost. The strap member 70 prevents the cover member 25, which protects the cylinder 9 for physically locking and unlocking the deadlock 30, from being lost, and constitutes the deadlock mechanism 3.

[0045] As shown in Figures 1 and 2, the grip portion 21 of the housing 20 of the outer handle 2 includes a main body portion 22 on the outside (the side opposite the main surface 8A) and a cover body 23 on the main surface 8A side. In the second direction X, the main body portion 22 has a total length approximately equal to the distance between the upper cover member 25 and the lower cover member 25, and is curved so as to be convex outward. In the second direction X, the cover body 23 has a total length LH approximately equal to the distance between the upper fixing portion 24 and the lower fixing portion 24, and is curved so as to be convex outward with approximately the same curvature as the main body portion 22. In the second direction X, the total length LH of the cover body 23 is shorter than the total length of the main body portion 22.

[0046] 2, a screw hole 27 is formed on the main surface 8A side of the cover body 23. A screw 28 is inserted into this screw hole 27. The main body 22 and the cover body 23 are connected to each other by this screw 28. Inside the gripping part 21 configured in this way, various electronic components (such as a circuit board and an antenna) for electronically locking and unlocking the deadlock 30 are housed.

[0047] In the third direction Z, the grip portion 21 is configured to be able to reciprocate toward and outward from the fixed portion 24 toward the main surface 8A. Hereinafter, such reciprocating motion in the third direction Z may be referred to as a "first reciprocating motion RM1" (see FIG. 6). As shown in FIG. 1, a space SP is formed between the main surface 8A of the door portion 8 and the cover body 23. Therefore, a user of the opening and closing device 1 can grasp the portion of the grip portion 21 where the cover body 23 is provided by passing their finger through this space SP. When the user pulls the gripped grip portion 21 outward (toward the user), the grip portion 21 moves outward from the fixed portion 24. When the user releases their hand from the grip portion 21, the grip portion 21 moves toward the main surface 8A and returns to its original position. In this way, the grip portion 21 performs the first reciprocating motion RM1 (see FIG. 6).

[0048] In this embodiment, as shown in FIG. 2 , the screw hole 27 is provided at a position shifted downward from the center 23C of the entire length LH (longitudinal direction) of the cover body 23. For example, the screw hole 27 may be provided at a position shifted downward from the center 23C of the cover body 23 by approximately 1 / 6 of the entire length LH. Alternatively, for example, in the case of a door used in a general residential building, the screw hole 27 may be provided at a position shifted downward from the center 23C by approximately 20 to 30 mm. In addition, in this embodiment, the screw 28 inserted into the screw hole 27 is inserted into the main body portion 22 side (outside) of the surface of the cover body 23 (the surface on the main surface 8A side). Typically, when a user grips the grip portion 21, it is considered that the user grips the cover body 23 near the center 23C. Therefore, by shifting the position of the screw hole 27 downward in this manner, it is possible to prevent the user's finger from getting stuck in the screw hole 27. Furthermore, since the screw 28 is inserted on the side of the main body 22 relative to the surface of the cover body 23, even if the user's finger gets into the screw hole 27, the user's finger is prevented from hitting the head of the screw 28.

[0049] 3 and 4, an operating portion 60 is housed on the main surface 8A side of the fixed portion 24 of the housing 20. This operating portion 60 operates in accordance with the first reciprocating motion RM1 of the gripping portion 21, and the operation of the operating portion 60 operates the latch bolt 1110. The operating portion 60 will be further described below.

[0050] Fig. 6 is a diagram for explaining the relationship between the latch lock 1000, the operating portion 60, and the grip portion 21 of the housing 20. Fig. 7 is a perspective view showing the operating portion 60. Fig. 8 is an exploded view of the operating portion 60. As shown in Figs. 6 to 8, the operating portion 60 includes a first member 61, a second member 62, a third member 63, a spacer 68, a first shaft 65, a second shaft 66, and a third shaft 67, each of which is a separate member.

[0051] The first member 61 is a member that generally forms the outer shell of the operating unit 60. The first member 61 includes linear portions 61Ba, 61Bb that can be seen as linear lines extending in the second direction X in a side view (when viewed from the first direction Y), and a storage portion 61A that can be seen as a substantially right-angled triangle in a side view. In a side view, the storage portion 61A protrudes from the linear portions 61Ba, 61Bb toward the main surface 8A. The storage portion 61A includes two plate members 61Aa, 61Aa that face each other in the first direction Y. At least a portion of the second member 62, at least a portion of the third member 63, and at least a portion of the spacer 68 are stored between these plate members 61Aa, 61Aa. The storage portion 61A has three holes formed therethrough in the first direction Y. The three holes of the accommodation portion 61A are a rectangular first hole portion 61H1 located on the lower side, a small-diameter circular second hole portion 61H2 located on the upper side and on the main surface 8A side, and a large-diameter circular third hole portion 61H3 located on the upper side and on the outer side (close to the linear portions 61Ba and 61Bb). The first hole portion 61H1 extends in the third direction Z (i.e., the direction of the first reciprocating motion RM1) and is formed in a track shape in this embodiment. In a side view, the linear portion 61Ba is located above the accommodation portion 61A, and the linear portion 61Bb is located below the accommodation portion 61A. The linear portions 61Ba and 61Bb are each provided with the above-mentioned fixtures 64, and the first member 61 is fixed to the door portion 8 via these fixtures 64. That is, the fixtures 64 fix the fixing portion 24 of the housing 20 to the door portion 8 and also fix the first member 61 to the door portion 8.

[0052] The spacer 68 has a generally right-angled triangular shape protruding toward the main surface 8A in a side view. The spacer 68 includes two thick portions 68A, 68A facing each other in the first direction Y. The spacer 68 has three holes formed therethrough in the first direction Y. The three holes are a rectangular first hole 68H1 located on the lower side, a small-diameter circular second hole 68H2 located on the upper side toward the main surface 8A, and a large-diameter circular third hole 68H3 located on the upper side and outside. The first hole 68H1 extends in the third direction Z (i.e., the direction of the first reciprocating motion RM1) and is formed in a track shape in this embodiment. The spacer 68 is accommodated in the accommodation portion 61A of the first member 61 and is adjacent to the accommodation portion 61A.

[0053] The second member 62 includes a linear portion 62B that can be seen as a straight line extending in the second direction X in a side view, and a main body portion 62A that can be seen as a substantially right-angled triangle in a side view. In a side view, the main body portion 62A protrudes from the linear portion 62B toward the main surface 8A. The main body portion 62A includes two plate members 62Aa that face each other in the first direction Y. A hole portion 62H1 extending in the second direction X is formed on the main surface 8A side of the main body portion 62A. In this embodiment, the hole portion 62H1 extends in the second direction X, which is a direction intersecting the third direction Z in which the first hole portion 61H1 of the first member 61 extends, and is formed in a track shape. The plate members 62Aa of the main body portion 62A are accommodated in the accommodation portion 61A of the first member 61 and are accommodated between two thick portions 68A of the spacer 68. The straight portion 62B of the second member 62 is fixed to the grip portion 21 of the housing 20. Therefore, the second member 62 can perform the first reciprocating motion RM1 together with the grip portion 21.

[0054] An intervening member Pa is attached to a portion of the linear portion 62B that is above the main body portion 62A in the second direction X. The intervening member Pa may be, for example, a member having at least one of the functions of a cushion and a spacer. By providing such an intervening member Pa, contact between the first member 61 or the end of the biasing member 69 (torsion spring) protruding from the first member 61 and the grip portion 21 is prevented, thereby preventing damage to the grip portion 21 due to such contact. Furthermore, when the intervening member Pa is a spacer, rattle of the operating portion 60 can be suppressed. Furthermore, when the intervening member Pa is a cushioning material, collision noise between members due to the first reciprocating motion RM1 of the grip portion 21 can be reduced.

[0055] The third member 63 is a plate-like member having a substantially W-shape in side view. The third member 63 includes a first extending portion 63A located on the upper side and extending in the third direction Z, a second extending portion 63B extending downward from the outer end of the first extending portion 63A, a third extending portion 63C extending outward from the lower end of the second extending portion 63B, and a fourth extending portion 63D extending diagonally downward and outward from the outer end of the third extending portion 63C. A first hole 63H1 is formed below the fourth extending portion 63D. The first hole 63H1 is formed in a track shape with its longitudinal direction aligned with the direction in which the fourth extending portion 63D extends (i.e., the direction inclined downward and outward). A circular second hole 63H2 is formed at the connection between the first extending portion 63A and the second extending portion 63B. The third member 63 is disposed so that the fourth extending portion 63D faces downward and the first extending portion 63A faces the main surface 8A. Furthermore, the third member 63 is disposed so that a portion of the fourth extending portion 63D is housed between the two plate members 62Aa, 62Aa of the second member 62. A majority of the first extending portion 63A of the third member 63 is located on the main surface 8A side of the portion of the first member 61 closest to the main surface 8A (the portion where the second hole portion 61H2 is formed), and protrudes from the first member 61 toward the main surface 8A.

[0056] 7, in the first direction Y, the third member 63 is housed in the first member 61 while being positioned between the two thick portions 68A, 68A of the spacer 68. Therefore, according to the operating portion 60 of the present embodiment, rattling of the third member 63 in the first direction Y within the first member 61 is suppressed. However, providing the spacer 68 is not essential.

[0057] As shown in Fig. 6, the first extension portion 63A of the third member 63 extends to the inside of one side surface 8C of the door portion 8. A latch lock 1000 including a latch bolt 1110 is housed inside the door portion 8. The first extension portion 63A of the third member 63 operates this latch lock 1000.

[0058] 7 and 8, the first member 61, the second member 62, the third member 63, and the spacer 68 are connected as follows. When the first member 61, the second member 62, the third member 63, and the spacer 68 are arranged as described above, the first hole 61H1 of the first member 61, the hole 62H1 of the second member 62, the first hole 63H1 of the third member 63, and the first hole 68H1 of the spacer 68 communicate with each other to form a first communication hole CH1. A first shaft 65 (shaft) is inserted through this first communication hole CH1. The diameter of the first shaft 65 is smaller than the dimensions of the first hole 61H1, the hole 62H1, the first hole 63H1, and the first hole 68H1. Among the holes forming the first communication hole CH1, the first holes 61H1 and 68H1 extend in the third direction Z, while the hole 62H extends in the second direction X. Therefore, the first shaft 65 is inserted into a region where the first holes 61H1 and 68H1 and the hole 62H intersect at right angles. This prevents the first shaft 65 from falling off the operating part 60.

[0059] The hole 62H1 of the second member 62 may have a diameter that is substantially the same as (or slightly larger than) the diameter of the first shaft 65. Even in this case, it is possible to prevent the first shaft 65 from falling off the operating part 60. However, by forming the hole 62H1 of the second member 62 to have a shape that extends in the second direction X, it becomes possible for the second member 62 to move in the second direction X relative to the first member 61, and it is possible to prevent stress from concentrating on the first shaft 65.

[0060] Furthermore, when the first member 61, the second member 62, the third member 63, and the spacer 68 are arranged as described above, the second hole 61H2 of the first member 61, the second hole 63H2 of the third member 63, and the second hole 68H2 of the spacer 68 communicate with each other to form a second communication hole CH2. A second shaft 66 is inserted through this second communication hole CH2. The diameter of the second shaft 66 is slightly smaller than but substantially the same as the dimensions of the second hole 61H2, the second hole 63H2, and the second hole 68H2. Furthermore, when the first member 61, the second member 62, the third member 63, and the spacer 68 are arranged as described above, the third hole 63H3 of the third member 63 and the third hole 68H3 of the spacer 68 communicate with each other to form a third communication hole CH3. A third shaft 67 is inserted through this third communication hole CH3. Here, the diameter of the third shaft 67 is slightly smaller than but substantially the same as the dimensions of the third hole portion 63H3 and the third hole portion 68H3. By inserting the first shaft 65, the second shaft 66, and the third shaft 67 in this manner, the first member 61, the second member 62, the third member 63, and the spacer 68 are connected together.

[0061] As described above, the third shaft 67 has a larger diameter than the first shaft 65 and the second shaft 66. A biasing member 69 (e.g., a torsion spring) is attached to the large-diameter third shaft 67. If the biasing member 69 is a torsion spring, the shaft 67 is inserted through a coil portion of the spring, one end of the spring biases the first shaft 65 toward the main surface 8A, and the other end of the spring is inserted through a hole (not shown) formed in the first member 61. That is, the biasing member 69 biases the first shaft 65 (shaft) inserted through the first communicating hole CH1 toward the main surface 8A, as shown by the outline arrow in FIG. 8, inside the first hole portions 61H1, 68H1 that communicate with each other and extend in the third direction Z (the direction of the first reciprocating motion). This biasing force presses the first shaft 65 against a part of the inner circumferential surface of the first hole portions 61H1, 68H1 that form the first communication hole CH1, eliminating the need to fix the first shaft 65 inside the first hole portions 61H1, 68H1 by other physical means or structural features.

[0062] The operation section 60 configured as described above operates as follows.

[0063] As shown in FIG. 6, when the grip portion 21 of the outer handle 2 is not gripped, the first shaft 65 is biased by the biasing member 69 and positioned at the end of the first hole portions 61H1, 68H1 that communicate with each other on the main surface 8A side. At this time, the first extension portion 63A of the third member 63 faces the main surface 8A side in the third direction Z. Here, when a user grips the grip portion 21 of the outer handle 2 and pulls the grip portion 21 toward the user (outside), the second member 62, which is fixed to the grip portion 21, also moves outward together with the grip portion 21. Then, as the second member 62 moves outward, the first shaft 65 (shaft) inserted through the hole portion 62H1 of the second member 62 is pushed outward by the second member 62 and moves outward within the first hole portions 61H1, 68H1 that communicate with each other. Here, because the first shaft 65 penetrates the first hole portion 63H1 of the third member 63, when the first shaft 65 moves outward, the third member 63 is pushed outward by the first shaft 65. As a result, the third member 63 attempts to rotate downward around the second shaft 66 that penetrates the second hole portion 63H2 of the third member 63. Here, the first hole portion 63H1 through which the first shaft 65, which is another shaft that penetrates the third member 63, penetrates extends in a direction that slopes downward and outward and has a dimension larger than that of the first shaft 65. Therefore, the first shaft 65 can move within this first hole portion 63H1. Therefore, when the first shaft 65 pushes the third member 63 outward, the third member 63 can rotate downward around the second shaft 66. As a result, the first extension portion 63A of the third member 63 moves downward. Then, as the first extension portion 63A moves downward, the first extension portion 63A presses an operated piece 1009 (see FIG. 10) of the latch lock 1000, which will be described later. This allows the latch bolt 1110 to rotate, and the door portion 8 to be opened.

[0064] Thereafter, when the user stops pulling on the grip portion 21 (for example, stops gripping the grip portion 21), the biasing force of the biasing member 69 causes the first shaft 65 (shaft) to move toward the main surface 8A and return to its original position. As a result, the second member 62 is also pushed by the first shaft 65 (shaft) and moves toward the main surface 6A, and the grip portion 21, which is fixed to the second member 62, also moves toward the main surface 8A. In this manner, as the second member 62 performs the first reciprocating motion RM1 together with the grip portion 21, the first shaft 65 (shaft) moves along the extension direction of the first holes 61H1, 68H1 that communicate with each other (the third direction Z, i.e., the direction of the first reciprocating motion RM1). Then, as the first shaft 65 (shaft) moves toward the main surface 8A and returns to its original position, the third member 63 rotates upward, and the first extension portion 63A of the third member 63 moves upward and returns to its original position. In this way, as the first axis 65 (axis) moves, the third member 63 performs the second reciprocating motion RM2 in a direction (in this embodiment, the second direction X) different from the direction of the first reciprocating motion RM1 (in this embodiment, the third direction Z).

[0065] In the operating unit 60 of this embodiment, the first member 61, the second member 62, the third member 63, and the spacer 68 are connected by a first shaft 65 (axis) that is separate from the first member 61, the second member 62, the third member 63, and the spacer 68, and the second reciprocating motion RM2 of the third member 63 is realized. With this configuration, stress concentration on the first shaft 65 is suppressed.

[0066] Next, the latch lock 1000 will be described.

[0067] 6, the latch lock 1000 is substantially entirely housed inside the door section 8, except for the latch bolt 1110 protruding from one side surface 8C of the door section 8. With the latch lock 1000 as a reference, the main surface 8A side in the third direction Z is the outdoor side, and the main surface 8B side in the third direction Z is the indoor side.

[0068] Fig. 9 is an enlarged rear view showing the latch lock 1000 with the latch lock lid 1001 attached. Fig. 10 is an enlarged rear view showing the latch lock 1000 with the latch lock lid 1001 removed.

[0069] As shown in Figures 9 and 10, the latch lock 1000 mainly comprises a latch lock cover 1001, a latch lock housing 1002, lock face side screws 1003, 1004, central side screws 1005, 1006, locking arms 1007, 1008, an operated piece 1009, a lock face 1010, a decorative panel 1010a, and a latch bolt assembly 1100.

[0070] The latch lock cover 1001 is a cover that covers an opening 1015 provided on the outdoor side in the third direction Z to close the opening 1015. The latch lock cover 1001 is fastened by screwing lock face side screws 1003, 1004 and center side screws 1005, 1006 into the latch lock housing 1002, respectively.

[0071] The latch lock housing 1002 is a box-shaped housing that houses the components of the latch lock 1000, including those described above, in an accommodation space formed inside. When the latch lock housing 1002 is attached to the door section 8, the lock face 1010 and the decorative panel 1010a are attached to one side surface 8C of the door section 8 so that the latch bolt 1110 (see FIG. 6) of the latch bolt assembly 1100 protrudes from one side surface 8C of the door section 8.

[0072] The latch lock housing 1002 has lock face-side screw holes 1011 and 1012 and central-side screw holes 1013 and 1014. The lock face-side screw holes 1011 and 1012 are formed in a lock face-side lid receiver 1016 bent from the upper side surface 1002a of the latch lock housing 1002 toward the opening 1015 (toward the upper side surface 1002a of the latch lock housing 1002), and in a lock face-side lid receiver 1017 bent from the lower side surface 1002b of the latch lock housing 1002 toward the opening 1015 (toward the upper side surface 1002a of the latch lock housing 1002). The central-side screw holes 1013 and 1014 are provided inside the latch lock housing 1002.

[0073] The lock surface side lid receiving portions 1016, 1017 are provided in positions close to the lock surface 1010 on the upper side surface 1002a and the lower side surface 1002b. By providing the lock surface side lid receiving portions 1016, 1017 in two locations, on the upper and lower sides, close to the lock surface 1010 on the upper side surface 1002a and the lower side surface 1002b, the strength of the latch lock housing 1002 near the lock surface 1010 can be increased. Furthermore, by configuring the latch lock housing 1002 in this manner, the latch lock lid 1001 can be prevented from floating even when a strong force is applied to the latch lock 1000 from the indoor / outdoor direction. Note that if the lid receiving portion is provided on the lock surface 1010, there is not enough space to provide sufficient reinforcement, and rigidity is reduced compared to when it is provided in positions close to the lock surface 1010 on the upper side surface 1002a and the lower side surface 1002b.

[0074] The latch lock 1000 is fixed to one side surface 8C of the door section 8 via a lock surface 1010 and a decorative plate 1010a.

[0075] The locking arms 1007 and 1008 are pivotally supported by central screw holes 1013 and 1014, and are rotatable about the central screw holes 1013 and 1014, which serve as fulcrums.

[0076] The locking arm 1007 is provided on the upper side in the second direction X of the door part 8. A locking protrusion 1018 is provided at the end of the locking arm 1007 on the lock surface side. The latch bolt 1110 is locked via this locking protrusion 1018, preventing the latch bolt 1110 from rotating. In addition, an engagement protrusion 1021 is provided at the end of the center side of the locking arm 1007 to connect and operate the locking arm 1007 with the locking arm 1008.

[0077] The locking arm 1008 is provided on the lower side of the door portion 8 in the second direction X. A locking protrusion 1019 is provided on the end of the locking arm 1008 on the lock surface side. The latch bolt 1110 is locked via this locking protrusion 1019, preventing the latch bolt 1110 from rotating. An operated piece 1009 that can come into contact with the first extension portion 63A (see FIG. 6) of the third member 63 of the operating unit 60 is provided on the end of the upper locking arm 1007. The provided operated piece 1009 causes the locking arms 1007 and 1008 to rotate about the central screw holes 1013 and 1014 in response to the second reciprocating motion RM2 of the first extension portion 63A. When the locking arms 1007 and 1008 rotate, the above-mentioned lock between the locking projections 1018 and 1019 and the latch bolt 1110 is released, and the latch bolt 1110 becomes rotatable.

[0078] An engagement hole 1020 is provided at the end on the central side of each of the locking arms 1007 and 1008, which receives an engagement protrusion 1021 for operating the locking arms 1007 and 1008 while the locking arms 1007 and 1008 are coupled together. When the engagement protrusion 1021 is received in the engagement hole 1020, the locking arms 1007 and 1008 move together, and as the locking arm 1007 rotates around the central screw hole 1013, the locking arm 1008 rotates around the central screw hole 1014. As a result, the latch bolt 1110 is released from engagement by the locking protrusions 1018 and 1019, and the latch bolt 1110 becomes rotatable. It is not necessary for the locking arms 1007 and 1008 to be connected by a protrusion such as the engaging protrusion 1021, and the locking arms 1007 and 1008 may be connected, for example, by inserting a shaft member with a retaining mechanism into holes formed in both the locking arms 1007 and 1008.

[0079] In the latch lock 1000, the latch bolt assembly 1100 is detachable from the latch lock housing 1002. The latch bolt assembly 1100 has a latch bolt 1110. As described above, the latch bolt 1110 protrudes from the latch lock housing 1002, and fits into a receiving portion (recess) of the door frame when the door section 8 is closed. When the door section 8 is opened or closed, the latch bolt 1110 is pressed by the door frame and temporarily retreats into the latch lock housing 1002, and protrudes from the latch lock housing 1002 when the pressing force from the door frame side is no longer acting.

[0080] Fig. 12 is a perspective view showing a latch bolt assembly 1100 of the latch lock 1000. Fig. 13 is an exploded perspective view showing a latch case 1120, latch bolt 1110, coil spring 1140, and pressing member 1130 of the latch bolt assembly 1100. Fig. 14 is a perspective view of the latch bolt 1110.

[0081] As shown in FIGS. 12 and 13, the latch bolt assembly 1100 of the latch lock 1000 is configured by assembling a latch bolt 1110, a coil spring 1140, and a pressing member 1130 to a latch case 1120.

[0082] As shown in Figures 12 to 14, the latch bolt 1110 is an inverted latch. The latch bolt 1110 has a closing contact portion 1111, an engaging protrusion 1112, an inner surface portion 1113, a rotation restricting portion 1119, and an opening contact portion 1114. The closing contact portion 1111 and the opening contact portion 1114 are provided on one side of the latch bolt 1110 in the first direction Y. The closing contact portion 1111 comes into contact with the door frame when the door unit 8 is closed. The opening contact portion 1114 comes into contact with the door frame when the door unit 8 is opened. Both the closing contact portion 1111 and the opening contact portion 1114 have flat or approximately flat surfaces, and form an acute angle when viewed from the second direction X.

[0083] A pressed portion is provided inside the closing contact portion 1111 and the opening contact portion 1114 of the latch bolt 1110. The pressed portion is a portion where the latch bolt 1110 is pressed by the coil spring 1140 via the pressing member 1130. When the pressed portion is pressed, the latch bolt 1110 protrudes from the latch case 1120 (latch lock housing 1002, door portion 8).

[0084] The inner surface portion 1113 has a shape such that a flat surface or a substantially flat surface extending in the second direction X on the indoor side of the latch bolt 1110 protrudes in the second direction X. The rotation restricting portion 1119 is located on the outdoor side of the inner surface portion 1113 in the third direction Z, and has a shape that protrudes in substantially the same manner as the inner surface portion 1113. When the latch bolt 1110 is housed in the latch case 1120, the inner surface portion 1113 and the rotation restricting portion 1119 each face the inner surface of a side wall portion 1124 on the indoor side, which will be described later. When the latch bolt 1110 is housed in the latch case 1120 and in the protruding position, the portions of the inner surface portion 1113 and the rotation restricting portion 1119 that protrude in the second direction X come into contact with the inner surface of a pillar portion 1121, which will be described later. The rotation of the inner side surface portion 1113 and the rotation restricting portion 1119 is restricted by the locking projections 1018, 1019, so that the latch bolt 1110 is locked as described above, and the latch bolt 1110 is prevented from rotating.

[0085] The inclined surface portion 1115 is a surface that is parallel or approximately parallel to the closing contact portion 1111 provided on the central side of the latch bolt 1110.

[0086] The opening contact portion 1114 is continuous and intersects with the closing contact portion 1111 and the inclined surface portion 1115. The closing contact portion 1111 is also continuous and intersects with the opening contact portion 1114 and the inner surface portion 1113. In other words, when the latch bolt 1110 is viewed from the second direction X, the closing contact portion 1111, the inner surface portion 1113, the opening contact portion 1114, and the inclined surface portion 1115 form the four sides of a rhombus.

[0087] The engaging protrusion 1112 is provided on the outdoor side of the latch bolt 1110, near the apex between the central end of the opening abutment portion 1114 and the outdoor end of the inclined surface portion 1115. The engaging protrusion 1112 protrudes in the second direction X, similar to the portion of the inner surface portion 1113 that protrudes in the second direction X. In this embodiment, the outdoor-side edge of the engaging protrusion 1112 is rounded and chamfered. As described above, the latch bolt 1110 becomes rotatable when the rotation restricting portion 1119 of the latch bolt 1110 is released from the engagement by the locking projections 1018, 1019. At this time, the latch bolt 1110 rotates about the engaging protrusion 1112 as a central axis, but by rounding and chamfering the outdoor-side edge of the engaging protrusion 1112, the engaging protrusion 1112 can easily roll on the pillar portion 1121 and the guide portion 1122 of the latch case 1120. The engaging protrusion 1112 may be formed in a cylindrical shape.

[0088] 13, the latch case 1120 is a member whose external shape is formed into a substantially rectangular parallelepiped shape. The latch case 1120 is configured by integrally molding a pillar portion 1121, a guide portion 1122, a spring accommodating portion 1123, and a side wall portion 1124 from a resin material, and a space for accommodating the latch bolt 1110 and the like is formed inside the latch case 1120.

[0089] The pillar portion 1121 is a pillar-shaped portion extending in the short direction of one side surface 8C of the door portion 8, provided on the lock face 1010 side of the latch lock 1000. When the latch bolt 1110 is in the protruding position, the engaging protrusion 1112 of the latch bolt 1110 comes into contact with the inner side surface portion 1113 and the rotation restricting portion 1119 of the latch bolt 1110, and the pillar portion 1121 functions as a retaining portion that retains the latch bolt 1110.

[0090] A pair of side walls 1124 are provided on the indoor and outdoor side surfaces of the latch case 1120. A groove-shaped guide portion 1122 for guiding the latch bolt 1110 is formed on the inside of each of the indoor and outdoor side walls 1124 (the side where the latch bolt 1110 and the like are accommodated).

[0091] The spring accommodating portion 1123 is provided toward the center of the latch case 1120 in the third direction Z. The indoor and outdoor sides of the spring accommodating portion 1123 are integrally molded with the respective side wall portions 1124. The spring accommodating portion 1123 is formed in a cylindrical or approximately cylindrical shape in the central portion so as to cover the end of the coil spring 1140 and the outer periphery surrounding it, thereby supporting the end of the coil spring 1140. The spring accommodating portion 1123 is integrally molded with the side wall portion 1124 by a columnar portion extending from the cylindrical or approximately cylindrical portion to the side wall portion 1124. Because the spring accommodating portion 1123 is formed in this manner, the latch case 1120 has open top and bottom sides (both sides in the second direction X).

[0092] The pressing member 1130 is formed in a substantially rectangular parallelepiped shape. The pressing member 1130 has a flat surface on the lock face 1010 side, and presses the pressed portion of the latch bolt 1110. The pressing member 1130 is also formed so that the center side can receive the end of the coil spring 1140.

[0093] As shown in FIG. 13 , the latch bolt assembly 1100 has a spring accommodating portion 1123 integrally molded with the latch case 1120, and the side surface in the second direction X and the left side surface of the latch case 1120 are open. Therefore, when assembling the latch bolt assembly 1100, the latch bolt 1110 can be inserted from the side surface in the second direction X as indicated by arrow A1, the pressing member 1130 as indicated by arrow A2, and the coil spring 1140 as indicated by arrow A3. In other words, the latch bolt 1110 reduces the number of parts and costs by integrating the latch case 1120 and the spring accommodating portion 1123, and simplifies assembly by allowing components to be inserted and assembled from the side. In particular, the latch lock 1000 requires the orientation of the latch bolt 1110 to be changed depending on the opening direction of the door section 8.

[0094] According to the latch bolt assembly 1100 described above, components such as the latch bolt 1110 can be easily attached to and detached from the latch case 1120, and a user such as a contractor for the door section 8 can easily change the orientation of the latch bolt 1110 to suit the door section 8. Furthermore, by providing the spring accommodating section 1123 in the latch case 1120, the latch bolt assembly 1100 can prevent components from falling off when they are removed.

[0095] Although arrows A1 to A3 in FIG. 13 indicate that latch bolt 1110, pressing member 1130, and coil spring 1140 are inserted from below, these members can also be inserted from above.

[0096] FIG. 11 is a cross-sectional view of the latch lock taken along line RR in FIG. 9, viewed from one side in the second direction.

[0097] 13 and 14, in the latch bolt assembly 1100 of the latch lock 1000, the engaging protrusion 1112 of the latch bolt 1110 is formed in a columnar or approximately columnar shape extending in the second direction X. Therefore, as shown in Fig. 11, when the latch bolt 1110 is in the protruding position, the engaging protrusion 1112 prevents interference with the locking protrusions 1018, 1019 of the locking arms 1007, 1008, and can prevent damage to the engaging protrusion 1112 even when a high load is applied to the latch lock 1000.

[0098] Next, the outer handle 2 will be described again. Specifically, part of the configuration of the outer side of the grip portion 21 of the outer handle 2 will be described.

[0099] As shown in FIG. 1, the outer portion of the grip portion 21 is formed by the main body 22 of the grip portion 21 of the housing 20. FIG. 15 is a perspective view of the outer handle 2 as seen from the outside (the side opposite the main surface 8A), showing the main body 22 in an exploded view. As shown in FIG. 15, the main body 22 includes a cover 22A and a base 22B. The base 22B is attached to a fixing portion 24 so as to perform a first reciprocating motion RM1. The cover 22A covers the base 22B from the outside and is fixed to the base 22B. FIG. 15 shows the cover 22A exploded from the base 22B. The internal space formed by the base 22B and the cover 22A houses various electronic components for electronically operating the deadlock mechanism 3, and these electronic components are fixed to the base 22B of the housing 20. The housing 20 constitutes the deadlock mechanism 3.

[0100] The main surface 22AF of the cover portion 22A forms part of the outer surface of the outer handle 2. The main surface 22AF of the cover portion 22A is provided with a window W that transmits light L generated inside the outer handle 2 to the outside of the outer handle 2, and a button Bu1 (push switch) for switching the deadlock mechanism 3 from a standby state to an active state, for example. The window W has a generally elliptical shape with the second direction X as its longitudinal direction. When a user presses the button Bu1 from the surface 22Aa (outer surface) of the main surface 22AF, power is supplied from the battery box 5 to the electronic components, and the electronic function of the deadlock mechanism 3 may be turned on. A container 40 is disposed in the portion overlapping the window W and the button Bu1 in the third direction Z. The container 40 is fixed to the inside of the housing 20, specifically, to the base 22B. In addition, an antenna and other electronic components (not shown) capable of receiving radio waves from a remote control to electronically operate the deadlock mechanism 3 are fixed to the lower part of the base 22B in the second direction X relative to the part to which the container 40 is fixed.

[0101] FIG. 16 is a perspective view showing the housing 40 with the cover portion 22A removed from the outer handle 2 and with a portion thereof disassembled. As shown in FIG. 16, the housing 40 includes a first component 41 and a second component 42. FIG. 16 shows the second component 42 of the housing 40 shown in FIG. 15 in an exploded view. The first component 41 is fixed to the cover portion 22A (housing 20), and a board 50 serving as an electronic component is fixed to the first component 41. The second component 42 has a shape that generally corresponds to that of the first component 41 when viewed from the third direction Z. The second component 42 covers the first component 41 and the board 50 fixed to the first component 41 from the outside in the third direction Z.

[0102] The substrate 50 fixed to the first component 41 is mounted with a switch Bu3 that is pressed and turned on by pressing the button Bu1, a plurality of light-emitting elements 51 (three in this embodiment), and the like. For example, turning on the switch Bu3 may cause the electronic function of the deadlock mechanism 3 to transition from a standby state to an active state, and power may be supplied from the battery box 5. The plurality of light-emitting elements 51 may be configured to emit different colors. For example, the plurality of light-emitting elements 51 may be configured such that one of the plurality of light-emitting elements 51 emits light in a first color when the switch Bu3 is turned on, another of the plurality of light-emitting elements 51 emits light in a second color when the deadlock 30 is in the unlocked state, and yet another of the plurality of light-emitting elements 51 emits light in a third color when the deadlock 30 is in the locked state. In this embodiment, the plurality of light-emitting elements 51 are mounted on the substrate 50 aligned in the first direction Y and mounted near the upper end of the substrate 50. Meanwhile, the switch Bu3 is mounted slightly below the center of the substrate 50 in the second direction X. Furthermore, wiring 52 is connected to the board 50 for supplying power to the board 50 and for the board 50 to send and receive signals. This wiring 52 is connected to the board 50 via a connector 53 attached to the lower end of the board 50, and is led out to the outside of the housing 40.

[0103] FIG. 17 is a view of the first component 41 of the housing 40 as viewed from the outside in the third direction Z. As shown in FIGS. 16 and 17, the first component 41 has a generally rectangular shape with the second direction X as the longitudinal direction when viewed from the outside. The material from which the first component 41 is formed is not particularly limited, but may be, for example, a resin, and more specifically, may be polypropylene (PP) resin. The first component 41 includes a rectangular bottom plate portion 412 and ribs 411 that surround the bottom plate portion 412 on four sides. The ribs 411 extend outward from the bottom plate portion 412 in the third direction Z.

[0104] The rib 411 includes a first rib 411a erected at an upper end of the bottom plate portion 412, a second rib 411b erected at one end of the bottom plate portion 412 in the first direction Y, a third rib 411c erected at the other end of the bottom plate portion 412 in the first direction Y, and a fourth rib 411d erected at a lower end of the bottom plate portion 412. Both ends of the first rib 411a in the first direction Y are connected to upper ends of the second rib 411b and the third rib 411c, respectively, and both ends of the fourth rib 411d in the first direction Y are connected to lower ends of the second rib 411b and the third rib 411c, respectively.

[0105] A hole 415 is formed in a lower portion of the bottom plate portion 412, penetrating the bottom plate portion 412 in the third direction Z. Meanwhile, a first engagement portion 414 is provided at an upper end of the bottom plate portion 412, extending outward in the third direction Z. This first engagement portion 414 may be, for example, a snap fit. The first component 41 also includes a plurality of (three in this embodiment) fastening portions 413. One fastening portion 413 is located above the first rib 411a and connected to the center of the first rib 411a in the first direction Y. The two fastening portions 413, 413 are located on both sides of the bottom plate portion 412 in the first direction Y and below the fourth rib 411d and connected to the fourth rib 411d. Fastening holes are formed in the fastening portions 413 for inserting fasteners such as screws or bolts.

[0106] 18 is a perspective view of the first component 41 as viewed from the principal surface 8A side in the third direction Z. As shown in FIG. 18, second engagement portions 416 extending toward the principal surface 8A side in the third direction Z are provided on both sides of the fourth rib 411d in the first direction Y. The second engagement portions 416 may be snap-fit, for example. Furthermore, a reinforcing portion 419 including three ribs extending in the first direction Y is provided on the principal surface 8A side of the bottom plate portion 412 of the first component 41.

[0107] The substrate 50 may be attached to the first component 41, for example, as follows.

[0108] 19, the substrate 50 is placed on the side where the rib 411 of the first component 41 protrudes. At this time, the side of the substrate 50 on which the connector 53, the switch Bu3, the plurality of light-emitting elements 51, etc. are mounted faces the side where the rib 411 protrudes. Then, the substrate 50 is tilted relative to the bottom plate portion 412 of the first component 41.

[0109] 20 , while maintaining the state in which the board 50 is tilted relative to the bottom plate portion 412 of the first component 41, the board 50 is passed through the hole 415 of the bottom plate portion 412, starting from the side where the rib 411 protrudes toward the opposite side, with the wiring 52 and connector 53 at the front. In other words, the hole 415 of the bottom plate portion 412 is formed so that the board 50, which is an electronic component, can be inserted in a state in which the board 50 is tilted relative to the bottom plate portion 412.

[0110] Then, as shown in FIG. 21 , the substrate 50, which is inclined relative to the bottom plate portion 412, is pressed against the bottom plate portion 412. As a result, the first engagement portion 414 engages with the surface of the substrate 50 on the side of the bottom plate portion 412 from which the rib 411 protrudes, on which the connector 53, the switch Bu3, the plurality of light-emitting elements 51, and the like are mounted. Meanwhile, the two second engagement portions 416 engage with the surface of the substrate 50 on the side opposite to the side from which the rib 411 protrudes, on which the connector 53, the switch Bu3, the plurality of light-emitting elements 51, and the like are mounted. In this way, the substrate 50 is held by the bottom plate portion 412. The bottom plate portion 412 of the first component 41 functions as a holding portion that holds the substrate 50. Therefore, hereinafter, the bottom plate portion 412 will be referred to as the “holding portion 412.”

[0111] In this way, the holding portion 412 of the first component 41 has a hole 415 formed therein through which the substrate 50 can be inserted while tilted relative to the holding portion 412. Therefore, even if the fourth rib 411d causes the rib 411 to surround the holding portion 412 on all four sides, by inserting the substrate 50 through the hole 415 as described above, the substrate 50 can be attached to the holding portion 412 without being interfered with by the wiring 52 or the connector 53.

[0112] 16, the second component 42 of the housing 40 is disposed on the side opposite the holding portion 412 with respect to the substrate 50 (electronic component) held by the holding portion 412. The second component 42 is a sheet-like member that is elastic, waterproof, and translucent, and may be made of, for example, silicone. When viewed from the third direction Z, the second component 42 has a substantially rectangular shape with the second direction X as its longitudinal direction. The second component 42 is provided with a rib 421, a translucent portion 422, a pressure transmitting portion Bu2, a connector cover portion 424, and the like.

[0113] The rib 421 of the second component 42 extends outward from the surface of the second component 42 on the opposite side (outer side in the third direction Z) from the side facing the substrate 50 (main surface 8A side in the third direction Z). In this embodiment, the rib 421 is located slightly inside the outer edge of the second component 42 and is provided around substantially the entire periphery of the second component 42. Therefore, the second component 42 includes an outer edge portion 423 that is the region between the rib 421 and the outer edge of the second component 42.

[0114] As shown in FIGS. 15 and 16 , the pressure transmission unit Bu2 of the second component 42 overlaps, in the third direction Z, a button Bu1 provided on the cover portion 22A of the main body 22 of the grip portion 21 and a switch Bu3 provided on the circuit board 50 fixed to the grip portion 21 of the first component 41, and is located between the button Bu1 and the switch Bu3. When a user presses the button Bu1, the user's pressure on the button Bu1 is transmitted to the switch Bu3 on the circuit board 50 via the pressure transmission unit Bu2, turning on the switch Bu3. As described above, a reinforcing portion 419 (see FIG. 18 ) including three ribs extending in the first direction Y is provided on the main surface 8A side of the bottom plate portion 412 of the first component 41. Such a reinforcing portion 419 may protect the circuit board 50 from pressure from the button Bu1.

[0115] Fig. 22 is a diagram showing the positional relationship between the first component 41 of the housing 40, the second component 42 of the housing 40, and the cover portion 22A as viewed from the main surface 8A side in the third direction Z. That is, when focusing on the main surface 22AF of the cover portion 22A in Fig. 22, the back surface 22Ab of the main surface 22AF is visible. The back surface 22Ab is the surface opposite to the front surface 22Aa (see Fig. 15) of the main surface 22AF.

[0116] As shown in FIG. 22, a rib 22Ac, multiple bosses 22bs, and the like are provided on the back surface 22Ab of the main surface 22AF of the cover portion 22A. The rib 22Ac is provided near the upper end of the cover portion 22A in the second direction X. The rib 22Ac stands upright from the back surface 22Ab toward the main surface 8A in the third direction Z. When viewed from the third direction Z, the rib 22Ac has a shape corresponding to the shape of the rib 421 (see FIG. 16) of the second component 42 of the container 40. Furthermore, when viewed from the third direction Z, the shape and dimensions of the inner circumferential surface 22Acf of the rib 22Ac are substantially equal to the shape and dimensions of the outer circumferential surface 421f (see FIG. 16) of the rib 421 of the second component 42. The multiple bosses 22bs stand upright from the back surface 22Ab toward the main surface 8A in the third direction Z. The multiple bosses 22bs are provided corresponding to the fastening portions 413 of the first component 41 described above (specifically, the number and positions of the bosses 22bs correspond to the fastening portions 413). Therefore, in this embodiment, three bosses 22bs are provided, and the three bosses 22bs include one boss 22bs located above the rib 22Ac and two bosses 22bs located below the rib 22Ac. Thread grooves are formed inside the three bosses 22bs for fastening fasteners such as screws or bolts.

[0117] Fig. 23 is a cross-sectional view taken along line AA in Fig. 1. Accordingly, Fig. 23 shows a cross-section of the portion of the outer handle 2 where the button Bu1 is located (i.e., the portion where the housing body 40 and the circuit board 50 are located) taken along the third direction Z. As described above, when viewed from the third direction Z, the shape and dimensions of the inner circumferential surface 22Acf of the rib 22Ac are substantially equal to the shape and dimensions of the outer circumferential surface 421f of the rib 421 of the second component 42 (see Figs. 16 and 22). Therefore, as shown in Fig. 22, by moving the surface of the second component 42 facing the rib 421 toward the back surface 22Ab of the main surface 22AF of the cover portion 22A and moving it toward the back surface 22Ab, the rib 421 of the second component 42 can be fitted into the rib 22Ac of the cover portion 22A, as shown in Fig. 23. Specifically, the ribs 421 of the second component 42 are fitted into the ribs 22Ac of the cover portion 22A with the outer peripheral surfaces 421f of the ribs 421 of the second component 42 and the inner peripheral surfaces 22Acf of the ribs 22Ac of the cover portion 22A being in surface contact along substantially the entire circumference. As a result, the outer edge portions 423 of the second component 42 and the ribs 22Ac of the cover portion 22A overlap in the third direction Z. Furthermore, as shown in FIG. 22 , the first component 41 holding the substrate 50 is pressed against the second component 42 with the substrate 50 facing the second component 42 fitted into the cover portion 22A. Specifically, fasteners 43 such as screws are inserted into the fastening holes of the three fastening portions 413 of the first component 41, and these fasteners 43 are screwed into the fastening holes of the three bosses 22bs on the back surface 22Ab of the cover portion 22A. 23 , the second component 42 is pressed in the third direction Z toward the main surface 22AF side of the cover portion 22A (the side opposite to the main surface 8A side) by the first component 41 holding the substrate 50. As a result, in the third direction Z, the outer edge portion 423 of the second component 42 is sandwiched between the rib 22Ac of the cover portion 22A and the second component 42, and the second component 42 is deformed by the pressing and comes into close contact with the rib 411 of the first component 41. At this time, the connector 53 of the substrate 50 is covered by the connector cover portion 424 of the second component 42.

[0118] According to this container 40, with the board 50 held by the holding portion 412 of the first component 41 surrounded on all four sides by the ribs 411 of the first component 41, i.e., with the board 50 surrounded by the ribs 411 all around, the second component 42 is in close contact with the ribs 411. This makes it possible to waterproof the entire outer periphery of the board 50 by the ribs 411, and also makes it possible to waterproof the outer surface of the board 50 (the surface on which the plurality of light-emitting elements 51 and the switch Bu3 are mounted) by covering it with the second component 42. Therefore, even if moisture seeps into the inside of the cover portion 22A through a gap formed in a portion of the main surface 22AF of the cover portion 22A where the button Bu1 is provided, for example, the moisture is prevented from reaching the board 50.

[0119] Next, the light transmitting portion 422 provided in the second component 42 will be described.

[0120] As shown in FIGS. 15, 16, and 22, the light-transmitting portion 422 is formed above the pressure transmitting portion Bu2 in the second direction X and has light-transmitting properties. As shown in FIG. 22, when viewed from the side opposite to the cover portion 22A side (the side of the main surface 8A in the third direction Z), the light-transmitting portion 422 includes an incident portion 422A extending in the first direction Y. The incident portion 422A faces the plurality of light-emitting elements 51 mounted on the substrate 50 and covers the plurality of light-emitting elements 51 from the outside in the third direction Z. That is, the incident portion 422A is on the side of the plurality of light-emitting elements 51. As described above, the plurality of light-emitting elements 51 are aligned in the first direction Y. That is, the incident portion 422A extends parallel to the direction in which the plurality of light-emitting elements 51 are aligned. Light L generated by each of the plurality of light-emitting elements 51 is incident on the incident portion 422A facing the plurality of light-emitting elements 51.

[0121] 15 and 16, when viewed from the cover portion 22A side (the outside in the third direction Z), the light-transmitting portion 422 includes an exit portion 422B extending in the second direction X, which is a direction intersecting (orthogonal to) the first direction Y. The exit portion 422B is formed integrally with the entrance portion 422A. The exit portion 422B is located on the opposite side to the side of the plurality of light-emitting elements 51, on the side where the rib 421 of the second component 42 is provided. Light L generated by each of the plurality of light-emitting elements 51 enters the entrance portion 422A and then exits from the exit portion 422B. More specifically, the light L generated by each of the plurality of light-emitting elements 51 passes through the light-transmitting portion 422 and is emitted from the emission portion 422B of the light-transmitting portion 422, becoming light having the second direction X as its longitudinal direction, passing through the window W having the second direction X as its longitudinal direction, and being emitted to the outside of the cover portion 22A (outer handle 2) (the side opposite to the main surface 8A side).

[0122] The light-transmitting portion 422 having such a configuration can emit light L that is long in the second direction X from the window W, so that when looking inside the outer handle 2 through the window W, it becomes difficult to see that the multiple light-emitting elements 51 are lined up in the first direction Y. Therefore, the light-transmitting portion 422 contributes to improving the aesthetic appearance of the outer handle 2.

[0123] (Second embodiment) Next, an opening / closing device according to a second embodiment will be described. FIG. 24 is a diagram showing a portion of an opening / closing device 200 according to this embodiment. In the opening / closing device 1 according to the first embodiment, the housing 20 of the deadlock mechanism 3 is provided in the outer handle 2. On the other hand, as shown in FIG. 24, in the opening / closing device 200, the housing 501 of the deadlock mechanism 3 is provided separately from the outer handle 220. In this respect, the opening / closing device 200 is mainly different from the opening / closing device 1 according to the first embodiment. However, other components of the opening / closing device 200 (such as the battery box 5, the box lock 6, the thumb turn 7, the door portion 8, and the latch bolt 1110 shown in FIG. 1) are generally similar to those of the opening / closing device 1. Therefore, hereinafter, the opening / closing device 200 will be mainly described with respect to the configuration of the housing 501 of the deadlock mechanism 3, and other components will be designated by the same reference numerals or omitted from the description unless necessary.

[0124] The housing 501 covers the cylinder 9 and constitutes part of a cylinder unit 500 that can electronically lock and unlock the deadlock 30 (see FIG. 1). That is, the cylinder unit 500 is configured as a separate body from the outer handle 2 and includes the housing 501 that houses part of the cylinder 9. FIG. 25 is a front perspective view of the cylinder unit 500 as seen from the outside. FIG. 26 is an exploded perspective view of the cylinder unit 500. As shown in FIGS. 25 and 26, the cylinder unit 500 includes the housing 501, a cover body 510, a circuit board 50 as an electronic component, a container body 540, and the cylinder 9. The cylinder unit 500 constitutes the deadlock mechanism 3.

[0125] FIG. 27 is a diagram showing a cylinder unit 500 attached to the door portion 8. As shown in FIGS. 26 and 27, a housing 501 of the cylinder unit 500 includes a base 504 fixed to the main surface 8A of the door portion 8, and a cover portion 508 located outside the base 504 and fixed to the base 504. The cylinder 9 is fitted inside the door portion 8. A head portion 9A (a portion where a keyhole is formed) of the cylinder 9 protrudes outward from the base 504 through a through-hole formed in a lower portion of the base 504. Meanwhile, a container 540, a circuit board 50 held in the container 540, and other electronic components 505 (e.g., an antenna) excluding the circuit board 50 are fixed to an upper portion of the base 504.

[0126] Fig. 28 is a perspective view showing the cover portion 508 of the housing 501 of the cylinder unit 500. As shown in Fig. 28, the cover portion 508 includes an upper storage portion 502, a lower surrounding portion 503, and a pair of side walls 506, 506.

[0127] In the third direction Z, the surrounding portion 503 of the cover portion 508 of the housing 501 bulges outward relative to the position of the main surface 8A of the door portion 8 and includes a pair of side portions 503S, 503S, a bottom wall 503B, and an outer wall 503A. The outer wall 503A is located outside relative to the position of the main surface 8A of the door portion 8 and is a substantially rectangular plate-like portion extending in the second direction X and the first direction Y. A circular through-hole 503CH is formed in approximately the center of the outer wall 503A. As shown in FIG. 26 , most of the cylinder 9 is located on the main surface 8A side of the outer wall 503A, and the head 9A of the cylinder 9 is exposed to the outside through the through-hole 503CH. When viewed from the outside in the third direction Z, the outer wall 503A of the surrounding portion 503 surrounds the periphery of the head 9A of the cylinder 9. A user of the cylinder unit 500 can insert a key into the head 9A of the cylinder 9 that protrudes outward from the through-hole 503CH.

[0128] As shown in FIG. 28 , the bottom wall 503B of the surrounding portion 503 is a substantially rectangular plate-like portion extending in the first direction Y and the third direction Z. The bottom wall 503B is located on the side of the surrounding portion 503 opposite the storage portion 502, and is connected to the lower end of the outer wall 503A. In the third direction Z, the bottom wall 503B extends to the position of the main surface 8A. In the third direction Z, a notch 503im is formed facing outward in an edge portion of the bottom wall 503B on the main surface 8A side. In the first direction Y, in this embodiment, the notch 503im is formed in the center of the bottom wall 503B, but the position of the notch 503im in the first direction Y is not particularly limited.

[0129] As shown in FIG. 28, the pair of side portions 503S, 503S of the surrounding portion 503 are located on both sides of the surrounding portion 503 in the first direction Y and are connected to both ends of the outer wall 503A in the first direction Y. The side portions 503S extend in the second direction X and the third direction Z. As shown in FIG. 29, the cover body 510 of the cylinder unit 500 is guided by the pair of side portions 503S, 503S and can slide relative to the housing 501 in the second direction X and along the main surface 8A. FIGS. 25 and 27 are views showing a state (closed state) in which the cover body 510 slides toward (upper side of) the accommodating portion 502 in the second direction X and comes into contact with the accommodating portion 502. In this closed state, the cover body 510 covers the head portion 9A of the cylinder 9 and most of the surrounding portion 503. 29 is a side view showing a state (open state) in which the cover body 510 is slid in the second direction X to the side opposite to the side of the storage section 502 (downward).

[0130] As shown in FIGS. 28 and 29, the side portion 503S of the surrounding portion 503 includes a slide surface 503G3, a first guide portion 503G1, and a second guide portion 503G2. The first guide portion 503G1 is located on the main surface 8A side of the slide surface 503G3 in the third direction Z and is in contact with the base 504 of the housing 501. The first guide portion 503G1 includes a first portion 503G1a extending in the second direction X and a second portion 503G1b extending in the first direction Y. The first portion 503G1a protrudes from the slide surface 503G3 on the side opposite the outer wall 503A in the first direction Y. The second portion 503G1b is connected to the lower end of the first portion 503G1a and extends in the first direction Y. Specifically, the second portion 503G1b extends in the first direction Y toward the cutout 503im of the bottom wall 503B. The second portion 503G1b is in contact with the bottom wall 503B. Ends in the first direction Y of the second portions G1b of the pair of side portions 503S, 503S face each other in the first direction Y with a gap Ga therebetween. The cutout 503im is located in the center of the gap Ga in the first direction Y. Such a cutout 503im allows moisture that has entered the inside of the housing 501 to be drained to the outside of the housing 501.

[0131] The second guide portion 503G2 is located on the opposite side (outside) of the slide surface 503G3 from the main surface 8A side in the third direction Z. The second guide portion 503G2 includes a guide main body 503G2a extending in the second direction X and a locking portion 503G2b extending in the third direction Z. The guide main body 503G2a protrudes in the first direction Y on the opposite side of the slide surface 503G3 from the outer wall 503A side. The locking portion 503G2b extends outward in the third direction Z from the lower end of the guide main body 503G2a.

[0132] The slide surface 503G3 is a surface extending in the second direction X, and a first guide portion 503G1 and a second guide portion 503G2 are provided on both sides of the slide surface 503G3 in the third direction Z. A protrusion 503P protruding from the slide surface 503G3 in the first direction Y is formed near the upper end of the slide surface 503G3. In this embodiment, the protrusion 503P protrudes in the shape of an isosceles trapezoid, but it may also protrude in the shape of an arc, for example.

[0133] As shown in FIGS. 26 and 28 , the accommodating portion 502 of the cover portion 508 of the housing 501 has a hollow rectangular parallelepiped shape with the main surface 8A side open. The accommodating portion 502 includes an upper top wall 502A, a lower bottom wall 502B, a pair of side portions 502S, 502S, and an outer wall 502F. The accommodating portion 502 and the base 504 form an accommodating space, and the accommodating body 540, the board 50, and other electronic components 505 are accommodated in this accommodating space. That is, the accommodating portion 502 of the housing 501 accommodates the accommodating body 540 and the board 50, which is an electronic component, inside. The accommodating body 540 is fixed to the inside of the accommodating portion 502 of the housing 501.

[0134] The outer wall 502F of the accommodating portion 502 is a square or rectangular plate-like portion extending in the second direction X and the first direction Y. The outer wall 502F is provided with a window W through which light L from the plurality of light-emitting elements 51 mounted on the substrate 50 passes, a button Bu1 (push switch) for switching the deadlock mechanism 3, for example, from a standby state to an operating state, and the like. In the third direction Z, the outer wall 502F of the accommodating portion 502 is located outward from the outer wall 503A of the enclosure 503. That is, the accommodating portion 502 protrudes outward (opposite the main surface 8A) from the enclosure 503 in the third direction Z. Since the accommodating portion 502 protrudes outward from the enclosure 503 in this manner, the above-described accommodating space is wide, and therefore, in addition to the enclosure 540 and the substrate 50, other electronic components 505 can also be accommodated inside the accommodating portion 502.

[0135] 26, the top wall 502A of the accommodation portion 502 is a rectangular plate-like portion extending in the first direction Y and the third direction Z. The top wall 502A is connected to the upper end of the outer wall 502F and extends toward the main surface 8A in the thickness direction.

[0136] As shown in FIG. 28 , the pair of side portions 502S, 502S of the accommodation portion 502 are connected to both ends of the outer wall 502F in the first direction Y and both ends of the top wall 502A in the first direction Y. The side portions 502S are rectangular plate-like portions extending in the second direction X and the third direction Z, and extend toward the main surface 8A in the third direction Z. A first portion 503G1a of the first guide portion 503G1 of the side portion 503S of the surrounding portion 503 includes a surface that is substantially flush with the side portion 502S of the accommodation portion 502. A bottom wall 502B of the accommodation portion 502 is connected to the lower end of the outer wall 502F and the lower ends of the pair of side portions 502S, 502S. The bottom wall 502B is a rectangular plate-like portion extending in the first direction Y and the third direction Z, and extends toward the main surface 8A in the third direction Z. The surrounding portion 503 is connected to the bottom wall 502B of the storage portion 502. The storage portion 502 and the surrounding portion 503 are aligned in the second direction X.

[0137] As shown in FIGS. 26 and 28, a pair of side walls 506, 506 of the cover portion 508 of the housing 501 are provided on both sides of the housing 501 (both sides in the first direction Y) when viewed from the third direction Z (a direction perpendicular to the main surface 8A of the door portion 8). Each of the pair of side walls 506, 506 is a plate-like portion formed in a substantially right-angled triangle when viewed from the first direction Y. Each of the pair of side walls 506, 506 is in contact with the bottom wall 502B of the accommodating portion 502 and the side portion 503S of the surrounding portion 503. A first portion 503G1a of the first guide portion 503G1 and a second guide portion 503G2 are located on the opposite side of the side wall 506 from the outer wall 503A side in the first direction Y. The side wall 506 is formed so that the length by which it protrudes outward in the third direction Z (the side opposite to the main surface 8A) increases as it moves from the side of the surrounding portion 503 (the lower side) to the side of the surrounding portion 502 (the upper side) in the second direction X (the direction in which the containing portion 502 and the surrounding portion 503 are aligned). That is, the length of the side wall 506 in the third direction Z increases toward the upper side of the side wall 506.

[0138] As described above, the upper accommodating portion 502 protrudes outward in the third direction Z relative to the surrounding portion 503, and therefore has a larger dimension than the surrounding portion 503, and tends to be heavier than the surrounding portion 503. In this embodiment, a pair of side walls 506, 506 that are longer in the third direction Z are provided at the upper side, which prevents the heavy upper accommodating portion 502 from bending downward.

[0139] 26, the cover body 510 of the cylinder unit 500, i.e., the cover body 510 of the deadlock mechanism 3 of this embodiment, has a hollow, approximately rectangular parallelepiped shape that is open on the upper side in the second direction X and on the main surface 8A side in the third direction Z. As shown in Fig. 25, the cover body 510 includes an outer wall 580, a pair of side portions 519, 519, and a bottom portion 510B.

[0140] The outer wall 580 is a rectangular plate-like portion extending in the second direction X and the first direction Y. In the third direction Z, the outer wall 580 is located at the same position as the outer wall 502F of the accommodating portion 502 of the cover portion 508 of the housing 501. Therefore, when the cover body 510 is in the closed state, the outer wall 580 of the cover body 510 is generally flush with the outer wall 502F of the cover portion 508 of the housing 501.

[0141] As shown in FIG. 25, the pair of side portions 519, 519 are connected to both end portions of the outer wall 580 in the first direction Y. The side portion 519 is a plate-shaped portion extending in the second direction X and the third direction Z, and extends toward the main surface 8A in the third direction Z. In the third direction Z, the end portion of the side portion 519 on the main surface 8A side contacts a first portion 503G1a of the first guide portion 503G1 of the side portion 503S of the enclosure portion 503. As shown in FIG. 26, a rail 513 and a first protrusion 590 are provided on each surface of the pair of side portions 519, 519 facing the enclosure portion 503 in the first direction Y. The rail 513 is provided at the end portion of the side portion 519 on the main surface 8A side in the third direction Z and protrudes toward the enclosure portion 503 in the first direction Y. The rail 513 extends in the second direction X from the upper end to the lower end of the side portion 519. A second protrusion 514 is provided at the upper end of the rail 513, protruding from the rail 513 toward the surrounding portion 503 in the first direction Y. In this embodiment, the second protrusion 514 protrudes in an arc shape, but may also protrude in the shape of an isosceles trapezoid, for example.

[0142] As shown in FIGS. 26 and 29, the rail 513 is fitted between the first guide portion 503G1 and the second guide portion 503G2 of the side portion 503S of the enclosure portion 503. Therefore, the cover body 510 can slide upward (toward the storage portion 502) and downward (toward the opposite side from the storage portion 502) along the slide surface 503G3, i.e., along the second direction X and the main surface 8A of the door portion 8. When the cover body 510 is slid upward, the second protrusion 514 of the rail 513 eventually climbs over the protrusion 503P of the slide surface 503G3, thereby engaging the second protrusion 514 with the protrusion 503P. Thus, the cover body 510 is in the closed state shown in FIGS. 25 and 27. In this closed state, the second protrusion 514 is engaged with the protrusion 503P, so the cover body 510 is held in the closed position unless the cover body 510 is pressed downward. In the closed state, the side 519 of the cover body 510, the first guide portion 503G1 of the side 503S of the covering portion 508 of the housing 501, and the side 502S of the accommodating portion 502 of the covering portion 508 of the housing 501 are generally flush with each other. On the other hand, when the cover body 510 is slid downward, the first protrusion 590 of the cover body 510 eventually engages with the locking portion 503G2b of the second guide portion 503G2 of the side 503S of the surrounding portion 503. In this manner, the cover body 510 enters the open state shown in FIG. 29. In this open state, the first protrusion 590 and the locking portion 503G2b are engaged with each other, so the cover body 510 is held in the open state position.

[0143] As shown in FIGS. 25 and 29 , the bottom 510B of the cover body 510 is connected to the lower end of the outer wall 580 and the lower ends of each of the pair of side portions 519, 519. That is, the bottom 510B is located on the opposite side (lower side) of the cover body 510 from the side (upper side) of the storage section 502. The bottom 510B is a plate-shaped portion extending in the first direction Y and the third direction Z, and extends toward the main surface 8A in the third direction Z. The bottom 510B includes a rectangular bottom main body 510Ba that occupies most of the bottom 510B, and a rectangular protruding portion 510Bb that protrudes from the bottom main body 510Ba toward the main surface 8A. In FIG. 25 , for convenience of explanation, the boundary between the bottom main body 510Ba and the protruding portion 510Bb is indicated by a dashed line; however, in this embodiment, the bottom main body 510Ba and the protruding portion 510Bb are integrally formed.

[0144] The bottom body 510Ba is connected to the outer wall 580 at its outer end in the third direction Z, and is connected to the pair of side portions 519, 519 at both ends in the first direction Y. In the closed state, the end of the bottom body 510Ba on the main surface 8A side contacts the first portion 503G1a of the first guide portion 503G1 of the surrounding portion 503.

[0145] The protrusion 510Bb protrudes from the bottom body 510Ba to the position of the main surface 8A in the third direction Z. Furthermore, the length of the protrusion 510Bb in the first direction Y is substantially equal to or slightly smaller than the gap Ga of the surrounding portion 503. Therefore, as shown in FIG. 25 , when the cover body 510 slides to the closed position where it contacts the accommodation portion 502, the protrusion 510Bb fits into the gap Ga. Thus, in the closed position, the bottom 510B of the cover body 510 and the second guide portion 503G2 of the cover portion 508 of the housing 501 are generally flush with each other. Therefore, in the closed position, the protrusion 510Bb covers the drainage notch 503im, and the housing 501 and the cover body 510 form the cylinder unit 500 having a substantially rectangular parallelepiped shape, contributing to improving the appearance of the cylinder unit 500. Furthermore, as described above, the protrusion 510Bb protrudes up to the position of the main surface 8A of the door portion 8, and therefore, as shown in FIG. 29, when the cover body 510 is slid along the main surface 8A, the cover body 510 is prevented from rattling toward the main surface 8A.

[0146] Next, the container 540 and the substrate 50 as an electronic component housed inside the container portion 502 of the housing 501 will be described.

[0147] 26, the substrate 50 has the same configuration as that of the first embodiment, and is equipped with a plurality of (three) light-emitting elements 51 aligned in a first direction Y (first direction), a switch Bu3 that is pressed by pressing the button Bu1, and a connector 53 for connecting the wiring 52 to the substrate 50. However, the housing 540 differs from the housing 40 according to the first embodiment mainly in the following points.

[0148] FIG. 30 is a perspective view showing how the container 540 is fixed to the base 504 of the housing 501. The second part 542 of the container 540 is a sheet-like member that is elastic, waterproof, and translucent, and may be made of, for example, silicone. As shown in FIGS. 26 and 30 , the second part 542 includes a translucent portion 422, a pressure transmitting portion Bu2, and a connector cover portion 424, similar to the second part 42 of the first embodiment. However, in this embodiment, the second part 542 has a rib 521 that is configured differently from the second part 42 of the first embodiment. The rib 521 extends outward from the surface of the second part 542 opposite the side facing the substrate 50 (the main surface 8A side in the third direction Z). In this embodiment, the rib 521 is located on the outer edge of the second part 542, and is provided on three sides of the entire circumference of the outer edge. Specifically, the rib 521 is provided on an upper side in the second direction X and on both sides in the first direction Y. The upper ends of the portions of the rib 521 provided on both sides in the first direction Y are connected to both ends in the first direction Y of the portion of the rib 521 that is on the upper side in the second direction X. In other words, the rib 521 has a substantially U-shape with an open lower side in the second direction X.

[0149] Fig. 31 is a cross-sectional view taken along line BB shown in Fig. 25. As shown in Fig. 31, a rib 509 having a shape corresponding to the shape of the rib 521 is formed on the surface (rear surface 502Fa) of an outer wall 502F of a cover portion 508 of a housing 501 on the side of the main surface 8A. The rib 509 extends from the rear surface 502Fa toward the main surface 8A in the third direction Z. The second component 542 is fixed to the housing 501 (specifically, to the rear surface 502Fa of the outer wall 502F of the cover portion 508) with the outer peripheral surface of the rib 521 contacting the inner peripheral surface of the rib 509 and fitted into the rib 509.

[0150] FIG. 32 is a diagram showing a state in which the second component 542 of the container 540 shown in FIG. 30 has been removed. As shown in FIGS. 26 and 32, the first component 541 of the container 540 is fixed to the base 504 of the housing 501, and the substrate 50 is fixed to this first component 541. When viewed from the outside in the third direction Z, the first component 541 has a generally rectangular shape with the second direction X as its longitudinal direction. The material forming the first component 541 is not particularly limited, but may be, for example, a resin, and more specifically, may be polypropylene (PP) resin. The first component 541 includes a rectangular bottom plate portion 512 and ribs 511 extending outward in the third direction Z from the bottom plate portion 512. The ribs 511 are provided on three sides. Specifically, the rib 511 includes a first rib 511a located on the upper side in the second direction X, a second rib 511b located on one side in the first direction Y, and a third rib 511c located on the other side in the first direction Y. The upper ends of the second rib 511b and the third rib 511c are connected to both ends of the first rib 511a in the first direction Y. That is, the rib 511 has a substantially U-shape with an open lower side in the second direction X. The area of the bottom plate portion 512 inside the rib 511, i.e., a first area 512A surrounded by the first rib 511a, the second rib 511b, and the third rib 511c, forms a holding portion 512A. The substrate 50 is fixed to this holding portion 512A to hold the substrate 50. More specifically, the substrate 50 is fixed to the holding portion 512A so that the connector 53 and the wiring 52 are located on the open side (lower side) where the rib 511 is not present, and so that the side on which the multiple light-emitting elements 51, the switch Bu3, and the connector 53 are mounted faces outward in the third direction Z. In this embodiment, the rib 511 is not provided on the lower side of the holding portion 512A, and the lower side is open. Therefore, when the substrate 50 is fixed to the holding portion 512A, even if the substrate 50 is moved in a direction perpendicular to the holding portion 512A and brought closer to the holding portion 512A, the rib 511 does not interfere with the wiring 52 or the connector 53. This makes it easy to fix the substrate 50 to the holding portion 512A.

[0151] Insertion holes 512C for inserting fasteners 43 from the main surface 8A side toward the outside in the third direction Z are formed in two corners on a diagonal line of one of the four corners of a second region 512B, which is a region of the bottom plate portion 512 outside the ribs 511. In addition, other electronic components 505 such as an antenna may be fixed to the second rib 511b and the third rib 511c on the side opposite to the substrate 50 side in the first direction Y.

[0152] As shown in Fig. 32, holes for inserting the fasteners 43 are formed in the base 504, corresponding to each of the two insertion holes 512C. Furthermore, as shown in Fig. 31, bosses 502Bs for inserting the fasteners 43 are provided on the back surface 502Fa of the outer wall 502F of the cover portion 508 of the housing 501, corresponding to each of the two insertion holes 512C. These bosses 502Bs extend from the back surface 502Fs toward the main surface 8A. A thread groove for threading the fasteners 43 is formed on the inner peripheral surface of the boss 502Bs. Therefore, after fitting the second part 542 into the rib 509 of the cover part 508, the substrate 50 is fixed to the holding part 512A of the first part 541 as described above, and as shown in FIG. 26, multiple (two in this embodiment) fasteners 43 are inserted from the main surface 8A side toward the outside through the holes in the base 504, the insertion holes 512C of the first part 541, and the bosses 502Bs of the cover part 508, and fastened to the bosses 502Bs, thereby fixing the container 540 and the substrate 50 to the cover part 508 of the housing 501, as shown in FIG. 31. Specifically, in the third direction Z, the second component 542 is located on the opposite side (outside) of the holding portion 512A side (main surface 8A side) of the substrate 50 held by the holding portion 512A of the first component 541, and is pressed by the rib 511 of the first component 541 toward the outer wall 502F side (outside opposite to the main surface 8A side) of the cover portion 508. As a result, the second component 542 is deformed by the above-mentioned pressing in the third direction Z and comes into close contact with the rib 511 of the first component 541. At this time, the connector 53 of the substrate 50 is covered by the connector cover portion 424 of the second component 542.

[0153] According to such a housing body 540, the board 50 held by the holding portion 512A of the first component 541 is surrounded on three sides by the ribs 511 of the first component 541, and the second component 542 is in close contact with the ribs 511. This allows the board 50 to be waterproofed except for its underside by the ribs 511, and also makes the outer surface of the board 50 (the surface on which the plurality of light-emitting elements 51 and the switch Bu3 are mounted) waterproof by being covered with the second component 542. Therefore, even if moisture seeps into the inside of the housing portion 502 through a gap formed in a portion of the outer wall 502F of the cover portion 508 where the button Bu1 is provided, for example, the moisture is prevented from reaching the board 50.

[0154] In this embodiment, the other electronic components 505 are located next to the substrate 50 in the first direction Y, and no other electronic components 505 are arranged below the substrate 50. Therefore, the underside of the substrate 50 does not need to be waterproofed. If moisture enters the interior of the accommodating section 502, the moisture can be drained to the outside of the accommodating section 502 via the notch 503im (see FIG. 28 ), as described above.

[0155] In addition, a person skilled in the art can appropriately modify the above-described opening and closing device in accordance with conventionally known knowledge. As long as the configuration of the present invention is still maintained even after such modification, it is of course included in the scope of the present invention. [Explanation of symbols]
