[0008] In one or more embodiments, the case comprises a case body having a storage section that is open at the top, a lid portion that can open and close the storage section of the case body, and a latch that is provided on the case body and can engage with the lid portion, and is a case that can be stacked in the vertical direction, wherein the latch has an axis portion fixed to the case and is provided rotatable around the axis of the axis portion, and is switchable between a first position where it engages with the lid portion and a second position where it engages with the case positioned above when multiple cases are stacked on top of each other.

[0009] In the above configuration, the latch can be rotated around the axis of the shaft, so that it can be engaged with the lid or the upper case at a specific position between the first position and the second position, thereby improving user convenience.

[0010] In one or more embodiments, the latch may be configured to apply a downward force to the lid in the first position.

[0011] In the above configuration, the latch applies a downward force to the lid when in the first position, so that the lid can be closed reliably.

[0012] In one or more embodiments, the latch may include a latch body capable of engaging with the lid and the case and having a second shaft portion parallel to the shaft portion, and a link member having one end connected to the shaft portion so as to be rotatable around the axis of the shaft portion and the other end connected to the second shaft portion so as to be rotatable around the axis of the second shaft portion.

[0013] In the above configuration, the link member allows the latch body to rotate about two rotation axes, the shaft portion and the second shaft portion, so that the latch position can be smoothly switched between the first position and the second position.

[0014] In one or more embodiments, the latch may have a first catch that catches with the lid in a first position and catches with the upper case in a second position.

[0015] In the above configuration, the first locking portion locks to the lid portion in the first position and locks to the upper case in the second position, thereby enabling the latch to be efficiently locked to the lid portion and the upper case by the single first locking portion.

[0016] In one or more embodiments, the latch may have a second catch that catches the lid in the second position.

[0017] In the above configuration, since the latch can also be engaged with the lid portion when in the second position, the lid portion can be closed by placing the latch in either the first position or the second position.

[0018] In one or more embodiments, the stem may be press fit into the case body.

[0019] In the above-described configuration, the shaft portion is press-fitted into the case body, so that it is possible to prevent the latch from falling off due to an impact or the like.

[0020] In one or more embodiments, the lid portion is movable between a protruding position in which it protrudes above the lid portion and a standby position below the lid portion, and may have a restricting member that, when positioned in the protruding position, abuts against the case positioned above in a stacked state to restrict movement of the case.

[0021] In the above configuration, since the restricting member is provided separately from the latch, the restricting member can be disposed at the protruding position to come into contact with the case disposed above and restrict the movement of the case. As a configuration using the restricting member, for example, a case can be stacked above in a state where the movement in three or less directions among the front-rear direction and the left-right direction is restricted by other restricting means, and the remaining movement directions among the front-rear direction and the left-right direction are switchably restricted by the restricting member. In this case, even in a state where the upper case is connected to the upper case by the latch or other connecting means (a state where the movement in the up-down direction is restricted), if there is a direction in which the movement is not restricted among the front-rear direction and the left-right direction, the upper case can be removed by moving the upper case in that direction. In contrast, by restricting the movement in all directions, the upper case does not move in either the front-rear direction or the left-right direction, and the connection with the upper case can be maintained. In this way, the restricting member makes it possible to switch between connection and disconnection with the case disposed above. Note that the restricting member may be disposed in all directions in the front-rear direction and the left-right direction.

[0022] In one or more embodiments, the regulating member has an arm portion extending in the vertical direction, the cover portion has a support portion having a recess or protrusion portion that supports the arm portion in each of the standby position and the protruding position, and the arm portion has a protrusion or recess portion that engages with the recess or protrusion portion of the support portion in the standby position and the protruding position, and may be elastically deformable by applying a force to the regulating member so that the protrusion or protrusion portion of the arm portion overcomes the recess or protrusion portion of the support portion.

[0023] In the above configuration, when the regulating member is disposed at the standby position and the protruding position, it is necessary to elastically deform the arm portion to move the regulating member so that the convex or concave portion of the arm portion overcomes the concave or convex portion of the support portion. Even if a force smaller than the force that elastically deforms the arm portion is applied, the regulating member does not move. This makes it possible to suppress positional deviation while allowing the regulating member to move in the vertical direction.

[0024] In one or more embodiments, the case further includes a shaft that connects the case body and the lid while penetrating a portion of the case body and a portion of the lid, the lid being rotatable about the axis of the shaft, the shaft having a return portion protruding from the outer peripheral surface at a portion of the axial direction, and may have a hollow portion inside the portion where the protrusion is provided.

[0025] In the above configuration, since the shaft has the return portion and the hollow portion, for example, when the shaft is inserted through a part of the case body and a part of the lid, the shaft can be deformed so that the return portion bends toward the hollow portion. Therefore, the shaft can be inserted smoothly. In addition, after the shaft is inserted, the return portion returns from the deformed state, thereby preventing the shaft from being displaced.

[0026] Hereinafter, an embodiment according to the present disclosure will be described with reference to the drawings, but the present disclosure is not limited to the embodiment. The components of the embodiments described below can be appropriately combined. In addition, some components may not be used.

[0027] In the embodiment, the positional relationship of each part will be described using the terms "left", "right", "front", "rear", "upper", and "lower". These terms indicate relative positions or directions based on the center of the case.

FIG. 2 is a perspective view showing an example of a case according to this embodiment. FIG. 3 is a perspective view showing another example of a case according to this embodiment. FIG. 4 is a view of the case in a stacked state as seen from the front. FIG. 5 is a diagram showing a configuration along the AA cross section in FIG. 4. FIG. 6 is a diagram showing a configuration along the BB cross section in FIG. 4. FIG. 7 is a diagram showing a configuration along the CC cross section in FIG. 6. FIG. 8 is a diagram showing a configuration along the DD cross section in FIG. 4.

[0029] As shown in Figures 1 to 7, the case stack structure 1 is configured by stacking three types of cases 100, 200, and 300 in five stages in the vertical direction. The cases 100, 200, and 300 can house and carry power tools, for example. The cases 100, 200, and 300 may be used individually or may be used as the case stack structure 1 as shown in Figures 1 to 7.

[0030] As shown in FIG. 2, the case 100 includes a case body 10, a lid portion 20, a latch 30, and a restricting member 40.

[0031] The case body 10 is in the shape of a rectangular box. The case body 10 has a front surface 10a, a rear surface 10b, a left surface 10c, a right surface 10d, a top surface 10e, and a bottom surface 10f. The case body 10 has a storage section 10g (see FIG. 5, etc.) with the top surface 10e open.

[0032] The front surface 10a is provided with a latch 30, a handle 11, and a groove portion 12. The latch 30 and the restricting member 40 will be described later. The handle 11 is rotatably attached to the case body 10. By grasping the handle 11 and pulling it forward, the handle 11 rotates and stands forward relative to the front surface 10a.

[0033] The groove portion 12 is disposed on both the left and right sides of the front surface 10a. The groove portion 12 is formed over the entire vertical direction. The groove portion 12 is formed so that the dimension (width) in the left and right direction is the same or almost the same over the top and bottom. The shape of the groove portion 12 is not limited to the above, and it may be configured to be formed in a part in the vertical direction, or may be configured so that the dimension in the left and right direction is not the same over the top and bottom. A protrusion portion 14 is provided at the lower end of the groove portion 12. The protrusion portion 14 is used when connecting cases together in a stacked state. Specifically, the protrusion portion 14 engages a latch 80 described later.

[0034] The top surface 10e is provided with a hinge portion 13. The hinge portion 13 is disposed at the rear end portion of the top surface 10e. The hinge portion 13 is used for connecting with the lid portion 20.

[0035] Side latches 16 are provided on the left surface 10c and the right surface 10d. The side latches 16 can be moved up and down to change their position between a position where they are engaged with the cover 20 and a position where they are engaged with the case disposed above in the stacked state. A protrusion 18 is provided below the side latch 16. The protrusion 18 engages a side latch 66, which will be described later. Although the left surface 10c side is shown in Figs. 1 to 7, a side latch 16 is also provided on the right surface 10d side so as to be symmetrical.

[0036] 3 includes a case body 110, a lid 20, a latch 30, and a restricting member 40. The case 200 has the same configurations as the case 100 with respect to the configurations of the lid 20, the latch 30, and the restricting member 40. The case 200 is also different from the case body 10 in that the case body 110 has a larger vertical dimension than the case body 10 and does not include a handle 11. The other configurations of the case body 110 are the same as those of the case body 10.

[0037] Each of the two cases 300 shown in FIG. 1 and FIGS. 4 to 7 includes a case body 60, a cover portion 70, and a latch 80. As shown in FIG.

[0038] The case body 60 is in the shape of a rectangular box. The case body 60 has a front surface 60a, a rear surface 60b, a left surface 60c, a right surface 60d, a top surface 60e, and a bottom surface 60f. The case body 60 has a storage section 60g with the top surface 60e being open.

[0039] The front surface 60a is provided with a latch 80 and a groove 62. The groove 62 is disposed on both the left and right sides of the front surface 60a. The groove 62 is formed over the entire vertical direction. The groove 62 is formed so that the dimension (width) in the left and right direction is the same or almost the same in the vertical direction. The shape of the groove 62 is not limited to the above, and may be a configuration in which it is formed in a part in the vertical direction, or a configuration in which the dimension in the left and right direction is not the same in the vertical direction. A protrusion 64 is provided at the lower end of the groove 62. The protrusion 64 engages the latch 30 (or the latch 80) of the case disposed below in a stacked state.

[0040] In addition, a side latch 66 and a protrusion 68 are provided on the left surface 60c and the right surface 60d.

[0041] Furthermore, the latch 80 has a configuration similar to that of the above-described side latch 16. That is, by moving the latch 80 in the vertical direction, the position can be changed between a position where it engages with the lid 70 and a position where it engages with the case disposed above in the stacked state.

[0042] Next, the configurations of the lid portion 20, the latch 30, and the restricting member 40, which are common to the case 100 and the case 200, will be described.

[0043] The lid portion 20 is disposed on the upper surface 10e of the case body 10. The lid portion 20 opens and closes the storage portion 10g. The lid portion 20 has a hinge portion 23. The hinge portion 23 is connected to the hinge portion 13 of the case body 10. A shaft 50 is used to connect the hinge portion 13 and the hinge portion 23. The shaft 50 is disposed in a state in which it penetrates the hinge portion 13 and the hinge portion 23 in the left-right direction. The lid portion 20 is rotatable around an axis of a rotation axis along the longitudinal direction of the shaft 50, i.e., the left-right direction. The lid portion 20 is opened and closed by this rotation. The lid portion 20 has a vertical regulation portion 25, a rear regulation portion 26, and a left-right regulation portion 27. The vertical restriction portion 25 is engaged with the legs 17 of the stacked cases 100, 200 and restricts the vertical movement of the cases 100, 200 (see Figs. 6 and 8). The rear restriction portion 26 is engaged with the legs (not shown) of the stacked cases 100, 200 and restricts the rearward movement of the cases 100, 200 (see Figs. 6 and 8). The left-right restriction portion 27 is engaged with the legs 18 of the stacked cases 100, 200 and restricts the left-right movement of the cases 100, 200 (see Figs. 6 and 8).

[0044] The shaft 50 has a return portion 51 and a hollow portion 52 (see FIG. 7). The return portion 51 is provided so as to protrude from the outer peripheral surface at a portion in the axial direction. The return portion 51 abuts against the end face 13a of the hinge portion 13, thereby suppressing misalignment of the shaft 50. The hollow portion 52 is formed inside the portion in the longitudinal direction of the shaft 50 where the return portion 51 is provided. By providing the hollow portion 52, when the shaft 50 is inserted so as to penetrate through the hinge portion 13 and the hinge portion 23, the return portion 51 deforms so as to enter the radially inward direction of the shaft 50 (dotted line in FIG. 7). Therefore, the shaft 50 can be smoothly positioned while preventing damage to the inner circumferences of the hinge portions 13 and 23.

[0045] The cover 20 has a handle 21 on the top surface 20a. The handle 21 is rotatably attached to the cover 20. By gripping the handle 21 and pulling it upward, the handle 21 rotates and stands above the top surface 20a.

[0046] The latch 30 is provided on the case body 10 and is capable of engaging with the cover portion 20 at a first position P1. Furthermore, the latch 30 is capable of engaging with the upper case at a second position P2 in a stacked state.

[0047] Fig. 9 is a perspective view showing an example of the latch 30. Fig. 10 is a cross-sectional view showing an example of the latch 30. The latch 30 has a case-side shaft portion (shaft portion) 31, a latch main body 32, and a link member 33.

[0048] The case side shaft portion 31 has a columnar or cylindrical shape, and is press-fitted into the case body 10. The case side shaft portion 31 is disposed along the left-right direction.

[0049] The latch body 32 is connected to the case side shaft portion 31 via a link member 33. The latch body 32 has a base portion 34 and a body side shaft portion (second shaft portion) 35. The base portion 34 is formed in, for example, a rectangular or substantially rectangular frame shape. The body side shaft portion 35 extends from both the left and right sides toward the center. The body side shaft portion 35 is provided parallel to the case side shaft portion 31.

[0050] The link member 33 has a base 33a, a case side connecting portion 33b, and a body side connecting portion 33c. The case side connecting portion 33b is provided at one end of the base 33a and connected to the case side shaft portion 31. The case side connecting portion 33b is connected to the case side shaft portion 31 so as to be rotatable around its axis. The body side connecting portion 33c is provided at the other end of the base 33a and connected to the body side shaft portion 35. The body side connecting portion 33c is connected to the body side shaft portion 35 so as to be rotatable around its axis. Due to such connection, the latch body 32 is rotatable around the axes of the two shaft portions, the case side shaft portion 31 and the body side shaft portion 35, via the link member 33.

[0051] In addition, the latch body 32 has a first locking portion 36 and a second locking portion 37 .

[0052] The first locking portion 36 is locked to the protrusion 24 of the lid 20 at the first position P1, and locked to the protrusion (protrusion 14 or protrusion 64) of the upper case at the second position P2. The first locking portion 36 has a protrusion 36a protruding downward. The first locking portion 36 is locked to the protrusion 24 with the protrusion 36a inserted into the recess 24b of the protrusion 24. In this state, the first locking portion 36 is restricted from moving in the front-rear direction by the protrusion 36a contacting the protrusion 24a at the front end of the protrusion 24. With the first locking portion 36 locked to the protrusion 24, the protrusion 36a presses the protrusion 24 downward by the elastic force of the latch 30. The second locking portion 37 is locked to the protrusion 24 of the lid 20 at the second position P2.

[0053] The operation of the latch 30 will be described. When the latch body 32 is moved downward so that the body-side shaft 35 is located below the case-side shaft 31 in a state where it is not engaged with the lid 20 or the upper case (unengaged state ST1 in FIG. 10), the case-side connecting portion 33b of the link mechanism 33 rotates around the axis of the case-side shaft 31, and the body-side connecting portion 33c rotates around the axis of the body-side shaft 35. This rotation of the link mechanism 33 allows the latch body 32 to be placed at the first position P1. From the state where the latch body 32 is placed at the first position P1, the first engaging portion 36 is engaged with the protrusion 24 of the lid 20, thereby entering the engaged state ST2 shown in FIG. 10. In the engaged state ST2, the protrusion 36a of the first engaging portion 36 of the latch 30 applies a downward elastic force to the protrusion 24. This allows the lid 20 to be closed reliably.

[0054] By pulling the upper part of the latch body 32 toward the front from the locked state ST2 around the body-side shaft 35, the first locking portion 36 is released from the protrusion 24 (unlocked state ST1 in FIG. 10). In the unlocked state ST1, the lid 20 can be opened and closed. In addition, since the case-side shaft 31 of the latch 30 is press-fitted and fixed into the case body 10, it is possible to prevent the latch 30 from falling off the case body 10.

[0055] In the unlocked state ST1, the latch body 32 is moved upward so that the body-side shaft portion 35 is located above the case-side shaft portion 31, whereby the case-side connecting portion 33b of the link mechanism 33 rotates about the axis of the case-side shaft portion 31, and the body-side connecting portion 33c rotates about the axis of the body-side shaft portion 35. This rotation of the link mechanism 33 allows the latch body 32 to be disposed at the second position P2. In this manner, by rotating the link mechanism 33 about the axes of the two shaft portions, the case-side shaft portion 31 and the body-side shaft portion 35, the latch body 32 can be easily disposed at the first position P1 and the second position P2, which are specific positions. With the latch body 32 disposed at the second position, the first locking portion 36 is locked to the protrusion 14 or the protrusion 64, and the second locking portion 37 is locked to the protrusion 24 of the cover portion 20, thereby resulting in the locked state ST3 shown in FIG. 10.

[0056] In addition, in a non-stacked state, i.e., in a state where no other cases are stacked above the case 100, the second locking portion 37 can be locked to the protrusion 24 of the lid portion 20 with the latch body 32 placed in the second position. In this case, the lid portion 20 is closed by the second locking portion 37. In this way, regardless of whether or not the cases are stacked, the lid portion 20 can be closed by the second locking portion 37 by placing the latch 30 in the second position P2.

[0057] The restricting member 40 is provided on the lid portion 20. The restricting member 40 is movable in the up-down direction. FIG. 11 is a diagram showing an example of the restricting member 40. FIG. 11 shows a case where the restricting member 40 is moved. By moving in the up-down direction, the restricting member 40 can be arranged at a protruding position P3 where it protrudes above the lid portion 20, and at a standby position P4 where it retreats downward from the lid portion 20. By being arranged at the protruding position P3, the restricting member 40 comes into contact with the front face or handle of the case arranged above in the stacked state, thereby restricting the forward movement of the case.

[0058] The restricting member 40 has a base portion 41, a branch portion 42, and an arm portion 43. The base portion 41 is formed in a state in which it extends in a band shape in the up-down direction. The branch portion 42 is provided so as to extend on both the left and right sides from the upper end of the base portion 41. The arm portion 43 is provided so as to extend downward from the tip of the branch portion 42.

[0059] The arm portion 43 is provided so as to be elastically deformable in the left-right direction. The arm portion 43 has a stopper 43a at its lower end. The stopper 43a is provided so as to come into contact with the support portion 15 when the regulating member 40 is disposed at the protruding position P3. Providing the stopper 43a makes it possible to prevent the regulating member 40 from moving upward beyond the protruding position P3. The arm portion 43 also has a protrusion 43b above the stopper 43a. The protrusion 43b protrudes toward the base portion 41. The arm portion 43 also has a protrusion 43c at its lower end. The protrusion 43c protrudes to the opposite side to the base 41 (shown enlarged within the area indicated by the two-dot chain line).

[0060] State ST11 of FIG. 11 shows a state in which the regulating member 40 is disposed at the standby position P4. In the state in which the regulating member 40 is disposed at the standby position P4, the protrusion 43c of the arm portion 43 is held in a state in which it is fitted into the recess 19a of the support portion 19. When the regulating member 40 is moved upward from this state, as shown in state ST12, the arm portions 43 on both sides are elastically deformed in a direction in which they close to the left and right, and the protrusion 43c passes over the recess 19a. In this way, when the regulating member 40 disposed at the standby position P4 is moved upward (state ST12), it is necessary to apply a force that allows the arm portion 43 to elastically deform so as to close in the left and right direction and allows the protrusion 43c to pass over the recess 19a. Therefore, even if a force smaller than this force is applied, the regulating member 40 does not move upward. In this way, the arm portion 43 of the regulating member 40 is elastically deformable, and the protrusion 43c is inserted into the recess 19a at the standby position P4, so that the positional deviation of the arm portion 43 in the vertical direction is suppressed.

[0061] When the arm portion 43 is elastically deformed to move the regulating member 40 upward, the protrusion 43b comes into contact with the inclined portion 15a at the lower end of the support portion 15. When the regulating member 40 is further moved upward, the arm portion 43 is elastically deformed in the left-right direction, and the protrusion 43b overcomes the inclined portion 15a and is inserted into the recess 15b. With the protrusion 43b inserted into the recess 15b, the regulating member 40 is disposed at the protruding position P3 (state ST13).

[0062] When the restricting member 40 arranged at the protruding position P3 is moved downward (state ST14), it is necessary to apply a force that allows the arm portion 43 to elastically deform so as to open in the left-right direction and the protrusion portion 43b to overcome the recess 15b. Therefore, even if a force smaller than the above force is applied, the restricting member 40 does not move downward. In this way, the restricting member 40 has an elastically deformable arm portion 43, and the protrusion portion 43b is inserted into the recess 15b at the protruding position P3, so that the positional displacement of the arm portion 43 in the vertical direction is suppressed.

[0063] As described above, in this embodiment, the cases 100, 200 are cases 100, 200 that can be stacked in the vertical direction and include a case body 10, 110 having a storage section 10g that is open at the top, a lid section 20 that can open and close the storage section 10g of the case body 10, 110, and a latch 30 that is provided on the case body 10, 110 and can engage with the lid section 20, and the latch 30 has a case side shaft section 31 fixed to the case 100, 200, and is provided rotatably around the axis of the case side shaft section 31, and may be able to switch between a first position P1 where it engages with the lid section 20 and a second position P2 where it engages with the case 100, 200, 300 that is positioned above in a stacked state in which multiple cases 100, 200 are stacked.

[0064] In the above configuration, the latch 30 can be rotated around the axis of the case side shaft portion 31, so that it can be engaged with the cover portion 20 or the upper case 100, 200, 300, etc. at a specific position between the first position P1 and the second position P2. This makes it possible to improve user convenience.

[0065] In this embodiment, the latch 30 may exert a downward elastic force in the first position P1.

[0066] In the above configuration, the latch 30 exerts a downward elastic force at the first position P1, so that the lid portion 20 can be reliably closed.

[0067] In this embodiment, the latch 30 may have a latch body 32 that is capable of engaging with the cover portion 20 and the cases 100, 200, and has a body side shaft portion 35 parallel to the case side shaft portion 31, and a link member 33 having one end connected to the case side shaft portion 31 so as to be rotatable around the axis of the case side shaft portion 31, and the other end connected to the body side shaft portion 35 so as to be rotatable around the axis of the body side shaft portion 35.

[0068] In the above configuration, the link member 33 allows the latch body 32 to rotate about two rotation axes, the case-side shaft portion 31 and the body-side shaft portion 35. Therefore, the locking position can be smoothly switched between the first position P1 and the second position P2.

[0069] In this embodiment, the latch 30 may have a first locking portion 36 that is locked to the lid portion 20 at a first position P1 and locked to the upper case at a second position P2.

[0070] In the above configuration, the first locking portion 36 is locked to the lid portion 20 at the first position P1 and locked to the upper case at the second position P2, so that the single first locking portion 36 can efficiently lock the latch 30 to the lid portion 20 and the upper case.

[0071] In this embodiment, the latch 30 may have a second locking portion 37 that is locked to the lid portion 20 in the second position P2.

[0072] In the above configuration, the latch 30 can also engage with the lid portion 20 in the second position P2, so that the lid portion 20 can be closed by placing the latch 30 in either the first position P1 or the second position P2.

[0073] In this embodiment, the case side shaft portion 31 may be press-fitted into the case main body 10, 110.

[0074] In the above-described configuration, the case side shaft portion 31 is press-fitted into the case main body 10, 110, so that the latch 30 can be prevented from falling off due to an impact or the like.

[0075] In this embodiment, the case bodies 10, 110 are arranged to be movable between a protruding position P3 protruding above the lid portion 20 and a waiting position P4 below the lid portion 20, and may have a regulating member 40 that, when positioned at the protruding position P3, regulates movement of the cases 100, 200 positioned above in the stacked state in at least one of the forward / backward and left / right directions.

[0076] In the above configuration, since the regulating member 40 is provided separately from the latch 30, by arranging the regulating member 40 at the protruding position P3, it is possible to abut against the upper case 100, 200 and appropriately regulate the movement of the case 100, 200 in at least one of the forward / rearward and left / right directions. As a configuration using the regulating member 40, for example, a configuration can be adopted in which the case 100, 200 is stacked on the upper side in a state in which the movement in three or less directions among the forward / rearward and left / right directions is regulated by other regulating means, and the remaining movement direction among the forward / rearward and left / right directions is switchably regulated by the regulating member 40. In this embodiment, as shown in Figs. 2 and 3, the upper case 100, 200 can be regulated in the upward / downward, backward, and left / right directions by the vertical regulating portion 25, the rear regulating portion 26, and the left / right regulating portion 27. Note that the upper case 100, 200 is provided with legs corresponding to the vertical regulating portion 25, the rear regulating portion 26, and the left / right regulating portion 27 when stacked. In this case, if forward movement is not restricted, the upper case 100, 200 can be removed by moving the upper case 100, 200 forward. In contrast, by arranging the restricting member 40 at the protruding position P3, movement in all directions, including the front-rear and left-right directions, is restricted, so that the upper case 100, 200 does not move in either the front-rear or left-right directions, and therefore the connection with the upper case 100, 200 can be maintained. In this way, the restricting member makes it possible to switch between connection and disconnection with the upper case 100, 200. Note that the restricting member may be arranged in all directions, including the front-rear and left-right directions.

[0077] In this embodiment, the regulating member 40 has an arm portion 43 extending in the vertical direction, the cover portion 20 has support portions 15, 19 having recesses 15b, 19a that support the arm portion 43 at the standby position P4 and the protruding position P3, respectively, and the arm portion 43 has protrusions 43b, 43c that engage with the recesses 15b, 19a of the support portions 15, 19 at the standby position P4 and the protruding position P3, and may be elastically deformable by applying a force to the regulating member 40 so that the protrusions 43b, 43c of the arm portion 43 overcome the recesses 15b, 19a of the support portions 15, 19.

[0078] In the above configuration, when the regulating member 40 is disposed at the standby position P4 and the protruding position P3, the arm portion 43 needs to be elastically deformed and moved so that the convex portions 43b, 43c of the arm portion 43 overcome the concave portions 15b, 19a of the supports 15, 19. Even if a force smaller than the force that elastically deforms the arm portion 43 is applied, the regulating member 40 does not move. This makes it possible to suppress positional deviation while allowing the regulating member 40 to move in the vertical direction.

[0079] In this embodiment, the case further includes a shaft 50 that connects the case body 10, 110 and the lid portion 20 while penetrating a portion of the case body 10, 110 and a portion of the lid portion 20, and the lid portion 20 is rotatably arranged around the axis of the shaft 50, and the shaft 50 has a return portion 51 protruding from the outer peripheral surface at part of the axial direction, and may have a hollow portion 52 inside the portion where the protrusion is provided.

[0080] In the above configuration, since the shaft 50 has the return portion 51 and the hollow portion 52, for example, when the shaft 50 is inserted through a part of the case body 10, 110 and a part of the lid portion 20, the shaft 50 can be deformed so that the return portion 51 bends toward the hollow portion 52. This allows the shaft 50 to be inserted smoothly. Furthermore, after the shaft 50 is inserted, the return portion 51 returns to its original state, thereby preventing the shaft 50 from being displaced.

[0081] The technical scope of the present invention is not limited to the above embodiment, and appropriate modifications can be made without departing from the spirit of the present invention. For example, in the above embodiment, the side latches 16 are arranged on the left surface 10c and the right surface 10d of the case body 10, but the present invention is not limited to this configuration. The above-mentioned latches 30 may be provided instead of the side latches 16. The same applies to the case body 110. [Explanation of symbols]
