Furthermore, the plate-shaped protrusions PT2 and PT3 may be provided at positions that are line-symmetrical with respect to a straight line that passes through the rotation axis AX of the output shaft S1 and the input shaft S2 and extends in the up-down direction.

[0029] In this embodiment, the housing 211 has a lower portion 211f that is substantially semicircular when viewed in the front-to-rear direction and an upper portion 211e that is substantially square when viewed in the front-to-rear direction. The left-to-right dimension of the lower portion 211f is smaller than the left-to-right dimension of the upper portion 211e, and the plate-like protrusions PT2 and PT3 are provided on the lower portion 211f such that the left-to-right outermost portions of the plate-like protrusions PT2 and PT3 are located more inward than the left-to-right outermost portions of the upper portion 211e. Therefore, despite having the plate-like protrusions PT2 and PT3, the housing 211 has a small left-to-right dimension.

The first driven gear G1 is a two-stage gear having a large diameter gear G11 and a small diameter gear G12, with the large diameter gear G11 meshing with the worm gear G0. The second driven gear G2 is a two-stage gear having a large diameter gear G21 and a small diameter gear G22, with the large diameter gear G21 meshing with the small diameter gear G12 of the first driven gear G1. The third driven gear G3 meshes with the small diameter gear G22 of the second driven gear G2. The output gear G4 is provided coaxially with the third driven gear G3 and integrally therewith.

[0035] The output shaft S1 (FIG. 6) is a round shaft-shaped member extending rearward along the front-rear direction from the rotation center of the third driven gear G3 and the output gear G4. The rear end surface of the output shaft S1 is provided with a recess R extending in the axial direction of the output shaft S1 (i.e., the front-rear direction). Ｓ１ (Figure 6) is provided.

[0036] The input shaft S2 extends forward in the front-rear direction from the rotation center of the third driven gear G3 and the output gear G4. The output shaft S1 and the input shaft S2 are coaxially connected to each other. The output shaft S1 and the input shaft S2 may be integral with each other.

[0037] When the output shaft 214S of the motor 214 rotates, the first driven gear G1, the second driven gear G2, the third driven gear G3, and the output gear G4 rotate about a rotation axis extending in the front-rear direction. The output shaft S1 and the input shaft S2 rotate integrally with the third driven gear G3 and the output gear S4 around the rotation axis AX extending in the front-rear direction.

[0038] As shown in FIG. 4 , the communication module 22 includes an antenna 221 and a communication interface 222 .

[0039] In this embodiment, the antenna 221 is configured to be able to perform wireless communication at 2.4 GHz and 5 GHz. However, the frequency of the wireless communication of the antenna 221 is not limited to these. Furthermore, the communication method of the antenna 221 is not particularly limited.

[0040] The communication interface 222 is connected to the antenna 221 and the controller 212 of the actuator module 21 .

[0041] The sound insulation mechanism 30 is a mechanism that suppresses transmission of the operating noise of the actuator module 21 to the surroundings by surrounding the actuator module 21. The operating noise of the actuator module 21 includes, for example, the driving noise of the motor 214, the driving noise of the power transmission unit 215, and sounds that are indirectly generated due to resonance of these driving noises.

[0043] The sound-insulating jacket 31 is a member that surrounds the actuator module 21 of the lock unit 20 and absorbs the operating sound of the actuator module 21. In the illustrated example, the sound-insulating jacket 31 is a box-shaped member. Note that the external shape of the sound-insulating jacket 31 is not limited to the illustrated example. For example, the sound-insulating jacket 31 may have a shape that is approximately similar to the housing 211 of the actuator unit 21. The sound-insulating jacket 31 may be formed from metal, resin, etc. A material with high sound-insulating performance may be used as the material for the sound-insulating jacket 31. Generally, the higher the specific gravity of a material, the better the sound-insulating performance, so a material with a high specific gravity may be used. Specifically, for example, metals such as iron and zinc may be used. Resins such as PA (polyamide) and PP (polypropylene) may be used. Resins with a higher specific gravity may also be used by mixing metal powder into them.

[0044] The sound-insulating jacket 31 includes a jacket base 311 and a jacket cover 312 .

[0045] The jacket base 311 is a substantially rectangular flat plate with its long sides extending in the up-down direction and its short sides extending in the left-right direction. ３１１ (Only three are shown in FIG. 2A).

One positioning hole AH is provided at each of the upper end and lower end of the jacket base 311 at the center of the left and right.

[0046] The jacket cover 312 (FIG. 2A) has a bathtub-shaped main body 312M that opens to the rear, and a flange 312F that extends vertically and horizontally from the main body 312M. The flange 312F is plate-shaped and extends in a plane perpendicular to the front-to-rear direction. The jacket cover 312 may be formed by drawing a plate-shaped member.

[0047] A circular opening OP is provided at the bottom center of the front surface of the main body 312M. ３１２ (an example of an "input shaft opening") is provided. ３１２ A cylindrical portion CL is provided on the outer periphery of the housing 10, extending forward in the front-rear direction.

The rear bushing 32 and the front bushing 33 may each be made of resin (POM (polyacetal) resin, for example).

[0050] The rear bushing 32 and the front bushing 33 have the same structure. As shown in Figure 2A, the rear bushing 32 and the front bushing 33 each have an annular portion AN, an inner cylindrical portion IC extending from the inner peripheral portion of the annular portion AN along one side of the axial direction of the annular portion AN, and an outer cylindrical portion OC extending from the outer peripheral portion of the annular portion AN along one side of the axial direction of the annular portion AN. The central axes of the annular portion AN, the inner cylindrical portion IC, and the outer cylindrical portion OC are all coincident. The length of the inner cylindrical portion IC is greater than the length of the outer cylindrical portion OC.

[0051] The sound-proofing mechanism 30 surrounds the periphery of the actuator module 21 by accommodating and holding the actuator module 21 of the lock unit 20 as follows.

The screw SC fixes the rubber RB to the support shaft SS, and thus fixes the actuator module 21 to the jacket base 31.

[0054] In this way, the actuator module 21 is supported by the support shaft SS via the rubber RB at three locations in the rotational direction when viewed from the front to the rear (i.e., the positions of the plate-shaped protrusions PT1, PT2, and PT3 shown in Figure 3), and is fixed to the jacket base 31.

[0055] The jacket cover 312 of the sound insulating jacket 31 is screwed to the jacket base 311 with the rear surface of the flange portion 312F in close contact with the front surface of the jacket base 311.

[0066] The communication module 22 can be disposed at any position outside the sound-insulating jacket 31. Specifically, the communication module 22 may be fixed to the front surface of the jacket cover 312, for example. Alternatively, the communication module 22 may be fixed to the surface of the door body 1000M opposite to the surface to which it is to be attached. In this case, a through-hole is provided in the door body 1000M for passing the harness 23 through. In the following description, it is assumed that the communication module 22 is fixed to the front surface of the jacket cover 312.

[0067] The cover 40 (FIG. 1) houses the lock unit 20 and the sound insulating mechanism 30 and is a part that constitutes the external appearance of the lock system 100. The cover 40 can be made of any material such as metal or resin. The cover 40 is bathtub-shaped and opens at the rear, and has a through-hole TH on the front. ４０ The cover 40 also has screw holes th on the left and right sides. ４０ (In FIG. 1, the screw holes th ４０ (Only the base 10 and the cover 40 are shown.) The combination of the base 10 and the cover 40, and the cover 40 are each an example of a "housing."

[0068] Specifically, the lock system 100 can be attached to the door 1000 as follows, for example.

[0069] First, the base 10 is attached to the mounting surface of the door body 1000M (i.e., the opening OP １０００ At this time, as shown in FIG. 1, the through-holes TH of the base 10 are fixed to the surface on which the through-holes TH are provided when viewed in the front-rear direction. １１ Door body 1000M opening OP １０００The base 10 can be fixed to the door main body 1000M by screws or the like (not shown).

[0070] Next, the sound-proof mechanism 30 surrounding the actuator module 21 is attached to the base 10. The output shaft S1 of the actuator module 21 is inserted through the opening OP of the door body 1000M. １０００ Insert it into the opening OP １０００ The deadbolt moving mechanism (not shown) is inserted into the recess R of the output shaft S1. Ｓ１ The sound-insulating mechanism 30 is positioned relative to the base 10 by inserting a positioning pin AP of the base 10 into a positioning hole AH (FIG. 2A) of the sound-insulating mechanism 30. The sound-insulating mechanism 30 is fixed to the base 10 using a screw hole (not shown) for the sound-insulating mechanism 30 of FIG. 2A, and using a screw hole th arranged along the upper side of the jacket base 311 for the sound-insulating mechanism 30 of FIG. 2B. ３１１ and screw holes th arranged along the bottom side ３１１ This can be achieved by means of a screw or the like (not shown) via the hole.

[0071] After the sound-proofing mechanism 30 is fixed to the base 10, the communication module 22 and the battery case 13 are connected by a wire (not shown). Power for driving the actuator module 21 is supplied to the actuator module 21 from a battery housed in the battery case 13 via the wire and the harness 23.

[0072] Next, the cover 40 is attached to the base 10. The cover 40 is fixed to the base 10 by screwing the screw holes th １２ and the screw holes th of the cover 40 ４０ This can be achieved by passing a screw through the base 10. In this way, the sound-proofing mechanism 30 surrounding the actuator module 21 is housed in the internal space defined by the base 10 and the cover 40.

[0073] When the cover 40 is attached to the base 10, the input shaft S2 of the lock unit 20 is inserted into the through hole TH of the cover 40. ４０ A thumb turn (not shown) is attached to the tip of the input shaft S2.

[0074] The lock system 100 attached to the door 1000 operates as follows.

[0075] A user of the lock system 100 uses any instruction device (specifically, for example, a mobile terminal such as a smartphone, or a remote control dedicated to unlocking, etc.) to cause the instruction device to send an unlock instruction or a lock instruction. Note that this instruction may be sent by the user operating the instruction device, or may be sent by the instruction device without user operation. The communication module 22 of the lock unit 20 receives the instruction via the antenna 221 and sends the instruction to the actuator module 21 via the communication interface 222. Note that the unlock and lock instructions from the instruction device may be received directly by the communication module 22 as described above, or may be received by a control unit (not shown) that receives the unlock and lock instructions and then sent from the control unit to the communication module 22 via a wired or wireless connection.

[0076] The controller 212 of the actuator module 21 controls the motor driver 213 in response to the received instruction to rotate the motor 214. As a result, if the received instruction is an unlock instruction, the motor 214 rotates in a direction to move the deadbolt 1000B to the stored position, and if the received instruction is a lock instruction, the motor 214 rotates in a direction to move the deadbolt 1000B to the extended position.

[0077] At this time, the actuator module 21 generates operating noise corresponding to the operation of the motor 214 and the operation of the power transmission unit 215. The sound insulation mechanism 30 absorbs the operating noise generated by the actuator module 21 with the sound insulation jacket 31, thereby suppressing the transmission of the operating noise to the outside.

[0078] The advantageous effects of the sound-proofing mechanism 30 of this embodiment and the lock module 100 equipped with the same are summarized below.

[0079] The sound-proofing mechanism 30 of this embodiment suppresses the propagation of operating noise by surrounding the actuator module 21, which has the motor 214 and power transmission unit 215 that generate operating noise, with a sound-proofing jacket 31 that is different from the housing 211 of the actuator module 21. Therefore, the propagation of operating noise can be effectively suppressed.

[0080] The sound-proof mechanism 30 of this embodiment has an opening OP ３１１ a rear bushing 32 that closes the gap between the outer periphery of the ３１２ The front bushing 33 closes the gap between the outer periphery of the input shaft S2 and the input shaft S3. This prevents the operating noise from leaking out of the gap, thereby effectively suppressing the propagation of the operating noise.

[0081] Furthermore, the rear bushing 32 allows movement in a transverse direction intersecting the axial direction (front-rear direction) of the output shaft S1, and the front bushing 33 allows movement in a transverse direction intersecting the axial direction (front-rear direction) of the input shaft S2. This reduces the positioning accuracy required when fixing the actuator module 21 to the sound-insulating jacket 31. Furthermore, the output shaft S1 and the input shaft S2 may move in the transverse direction due to vibrations, etc. Therefore, by allowing movement in the transverse direction, it is possible to prevent undesirable forces from being applied to the output shaft S1 and the input shaft S2 due to vibrations, etc.

[0082] In the sound insulation mechanism 30 of this embodiment, the actuator module 21 is fixed to the sound insulation jacket 31 via a support shaft SS provided on the inner surface of the sound insulation jacket 31 and a rubber RB provided around the support shaft SS. This allows the vibration of the actuator module 21 to be absorbed by the rubber RB, thereby more effectively suppressing the propagation of operating noise to the sound insulation jacket 31 and, ultimately, to the surrounding area.

[0083] Furthermore, the sound-proof mechanism 30 of this embodiment uses the support shaft SS to support the actuator module 21 without contacting the sound-proof jacket 31. This effectively prevents the operation noise from being transmitted to the sound-proof jacket 31 and, ultimately, to the surrounding area.

[0084] In this embodiment, the sound-proofing mechanism 30 supports the actuator module 21 via the support shaft SS at three plate-shaped protrusions PT1, PT2, and PT3, which are spaced apart in the rotational direction of the output shaft S1 and the input shaft S2. Therefore, compared to when the actuator module 21 is supported at two points, vibration and rotation of the actuator module 21 are less likely to occur. Furthermore, in this embodiment, the plate-shaped protrusions PT2 and PT3 are positioned rotationally symmetrically with respect to the rotational axis AX of the output shaft S1 and the input shaft S2. This allows the support loads applied to the plate-shaped protrusions PT2 and PT3 to be similar in magnitude, thereby enabling the use of common designs and components for the plate-shaped protrusions PT2 and PT3. Furthermore, in this embodiment, the plate-shaped protrusions PT2 and PT3 are positioned line-symmetrically with respect to a line extending vertically through the rotational axis AX of the output shaft S1 and the input shaft S2. This makes the support load applied to the plate-shaped protrusion PT2 and the support load applied to the plate-shaped protrusion PT3 the same or more similar in magnitude.

[0085] The sound-insulating jacket 31 of the sound-insulating mechanism 30 of this embodiment has a wiring opening OP for passing the harness 23 connecting the actuator module 21 and the communication module 22. Ｗ Therefore, the communication module 22 can be disposed at any position outside the sound-insulating jacket 31. This is advantageous in that the communication module 22 can be disposed at a suitable position suitable for wireless communication.

[0086] The lock system 100 of this embodiment has a cover 40 that houses the sound-insulating jacket 31. Therefore, the sound-insulating jacket 31 can be designed without considering aesthetics. This is advantageous in that it increases design freedom and reduces manufacturing costs.

[0087] Furthermore, in comparison with Patent Document 1, the present disclosure suppresses the propagation of the operating sound of the lock module by using a sound-proofing mechanism that is different from the housing of the lock module, unlike Patent Document 1. Therefore, better noise suppression can be achieved compared to the technology described in Patent Document 1, which attempts to reduce noise by using the housing itself.

[0088] [Modifications] The following modifications can also be used in the above embodiment.

[0089] [Variation 1] In the above embodiment, the sound-insulating jacket 31 of the sound-insulating mechanism 30 includes a plate-shaped jacket base 311 and a bathtub-shaped jacket cover 312. However, the configuration of the sound-insulating jacket 31 is not limited to this. The sound-insulating jacket 31 may have any configuration that surrounds the actuator module 21 of the lock unit 20 and suppresses propagation of the operating sound of the actuator module 21 to the surrounding area.

[0090] Specifically, for example, a sound insulating jacket 35 including a jacket case 351 and a jacket cover 352 as shown in FIG. 9 may be used.

[0091] The jacket case 351 has a rear wall 351b whose long sides are in the up-down direction and whose short sides are in the left-right direction, and a peripheral wall 351w that stands upright forward from the outer periphery of the rear wall 351b. ３５１ is provided.

[0092] When viewed from the front, the contour of the inner circumferential surface of the peripheral wall 351w is shaped to follow the contour of the actuator module 21. A notch NT is provided in the portion of the peripheral wall 351w that rises from the right end of the rear wall 351b. Screw holes th are provided at the four corners of the front end surface of the peripheral wall 351w. ３５１ is provided.

[0093] The jacket cover 352 is a rectangular flat plate with its long sides extending in the up-down direction and its short sides extending in the left-right direction. ３５２ The jacket cover 352 has an opening OP on the front surface thereof. ３５２ The jacket cover 352 has a cylindrical portion CL extending forward from the periphery thereof. ３５２ is provided.

[0094] The jacket cover 352 is inserted through the screw holes of the jacket case 351. ３５１ and the screw holes th of the jacket cover 352 ３５２The wiring opening OP is formed by the notch NT and the jacket cover 352. Ｗ is defined.

[0095] [Modification 2] In the sound insulating jacket 35, a jacket case 353 as shown in Fig. 10 may be used instead of the jacket case 351. The jacket case 353 has a rear wall 353b and a peripheral wall 353w, and a circular opening OP is formed in the rear wall 353b. ３５３ The rear wall 353b is provided with one positioning hole AH at the top end and one at the bottom end in the center of the left and right sides. The peripheral wall 353w differs from the peripheral wall 351w of the jacket case 351 in that the outline of the inner peripheral surface of the peripheral wall 353w is rectangular when viewed from the front.

[0096] [Modification 3] In the above embodiment, the actuator module 21 is fixed to the sound-insulating jacket 31 using the support shaft SS and the rubber RB. However, this is not limited to this. The actuator module can be fixed to the sound-insulating jacket in any manner.

[0097] Specifically, for example, as shown in Figure 9, the actuator module 21 may be fixed to the sound-insulating jacket 35 using plate-shaped sponges SPa, SPb, SPc, SPd, and SPe that are arranged in front, behind, left, right, and below the actuator module 21, respectively.

[0098] One side of each of the sponges SPa to SPe is attached to the actuator module 21 with double-sided tape, and the other side is attached with double-sided tape to the jacket case 351 or the jacket cover 352. In this way, the actuator module 21 is fixed to the sound-insulating jacket 35 without coming into contact with the sound-insulating jacket 35 via the sponges SPa to SPe, which have the function of absorbing vibrations of the actuator module 21, in a manner that makes it difficult for vibrations (and therefore sound) to be transmitted to the sound-insulating jacket 35.

[0099] 9 shows an embodiment in which sponges SPa to SPe are used to secure the actuator module 21 to the sound-insulating jacket 35, but the present invention is not limited to this. The actuator module 21 may be secured to the sound-insulating jacket 31 using sponges in the same manner as shown in FIG. 9. Alternatively, the actuator module 21 may be secured to the sound-insulating jacket 35 using a support shaft and rubber in the same manner as shown in FIG. 2A.

[0100] In the above description, rubber RB is an example of a material having a vibration absorbing function. Any vibration absorbing material having a vibration absorbing function may be used instead of rubber RB. For example, urethane may be used as the vibration absorbing material.

[0101] In the above description, the sponges SPa to SPe are examples of members having a vibration absorbing function. Any plate-shaped vibration absorbing member having a vibration absorbing function may be used in place of the sponges SPa to SPe. For example, a gel sheet may be used as the plate-shaped vibration absorbing member.

[0102] [Modification 4] In the above embodiment and modification, the wiring opening OP Ｗ 2, wiring opening OP Ｗ A sealing member CM (FIG. 9) may be attached to close the gap between the outer periphery of the wiring opening OP and the harness 23. Ｗ Alternatively, the cap may be a cap having a plate portion inserted into the gap between the outer periphery of the harness 23 and the wiring opening OP and a plate-shaped lid portion perpendicular to the plate portion. Ｗ The sealing member CM may be a bushing that fills the gap between the harness 23 and the outer periphery of the sound-insulating jacket 31 (details will be described later in Modification 8 below). The sealing member CM may be made of, for example, rubber. When a bushing is used as the sealing member CM, the transmission of vibrations from the harness 23 to the sound-insulating jacket 31 is suppressed, and the propagation of operating noise can be more effectively suppressed.

[0103] [Modification 5] In the above embodiment, the front bushing 33 may be replaced with a front bushing 37 shown in FIG. 11(a).

[0104] The forward bushing 37 has an annular portion AN, an outer tube portion OC extending from the outer periphery of the annular portion AN to one side in the axial direction of the annular portion AN, an inner tube portion IC extending from the inner periphery of the annular portion AN to both sides in the axial direction of the annular portion AN, and a lid portion CV that closes the inner tube portion IC on the other side in the axial direction of the annular portion AN.

[0105] As shown in FIG. 11(b) and FIG. 11(c), the front bushing 37 is opened. ３１２ When the front bushing 37 is attached to the rear surface AN of the annular portion AN of the front bushing 37, ＲＥ is the front end surface CL of the cylindrical portion CL ＦＲ In addition, the inner peripheral surface OC of the outer cylindrical portion OC of the front bushing 37 ＩＮ is the outer circumferential surface CL of the cylindrical portion CL ＯＵＴ and the outer peripheral surface IC of the inner cylindrical portion IC of the front bushing 37 ＯＵＴ is the inner circumferential surface CL of the cylindrical portion CL ＩＮ On the other hand, the inner peripheral surface IC of the inner cylindrical portion IC of the front bushing 37 ＩＮ and the outer peripheral surface S2 of the input shaft S2 ＯＵＴ There is a gap GP between them.

[0106] In this modified example, the rear surface OC of the outer cylindrical portion OC of the front bushing 37 ＲＥ and the front surface 312 of the jacket cover 312 ＦＲ 11(b) and 11(c), they may be in contact with each other, or there may be a gap therebetween. ＲＥ and the front surface 312 of the jacket cover 312 ＦＲ and abut against each other, while the rear surface AN of the annular portion AN of the front bush 33 ＲＥ and the front surface 312 of the jacket cover 312 ＦＲ The front end surface CL of the cylindrical portion CL ＦＲ A gap may be formed between the

[0107] Inner surface IC of inner cylindrical part IC ＩＮ is the outer peripheral surface S2 of the input shaft S2 having a pair of D-cut surfaces DCS. ＯＵＴ Therefore, the inner peripheral surface IC of the inner cylindrical portion IC of the front bushing 37 ＩＮ and the outer peripheral surface S2 of the input shaft S2 ＯＵＴThe distance between the input shaft S2 and the input shaft S3 is substantially constant over the entire axial and circumferential areas of the input shaft S2.

[0108] The cover CV has a first portion CV1 in the shape of a disk located at the end of the inner cylinder IC and a second portion CV2 in the shape of a thick plate protruding from the first portion CV1. The second portion CV2 may be a thumb turn, or a thumb turn may be connected to the second portion CV2.

[0109] Outer circumferential surface S2 of input shaft S2 ＯＵＴ The inner circumferential surface IC of the inner cylindrical portion IC of the front bushing 37 is provided with a D-cut surface DCS. ＩＮ A part of the front bushing 37 faces the D-cut surface DCS at a fixed distance. Therefore, the front bushing 37 and the input shaft S2 rotate substantially integrally. The front bushing 37 rotates while maintaining contact with the cylindrical portion CL.

[0110] By using the front bushing 37, the opening OP ３１２ and the input shaft S2 can be more effectively closed.

[0111] In the above embodiment, any bushing may be used in place of the rear bushing 32 and / or the front bushing 33. The bushing may form a labyrinth structure between itself and the sound-insulating jacket 31. In the above embodiment, the rear bushing 32 and / or the front bushing 33 may be omitted.

[0112] [Modification 6] In the above embodiment and modification, the wiring opening OP Ｗ 12, in a state where the sound-insulating jacket 37 is fixed to the actuator module 21, a wiring opening OP is provided on the opposite side of the connection portion CN between the harness 23 and the actuator module 21 with respect to the actuator module 21. Ｗ may be provided.

[0113] 12 has a flat jacket base 371 and a bathtub-shaped jacket cover 372. The jacket cover 372 is fixed to the jacket base 371 with screws. In this state, a notch NT provided on the left side of the jacket base 371 and a rear end 372 of the jacket cover 372 are in contact with each other. ＲＥ (FIG. 13) and the wiring opening OP Ｗ is defined.

[0114] The three plate-like protrusions PT1 to PT3 of the actuator module 21 are supported by three support shafts SS that stand upright forward from the front surface of the jacket base 371, via rubber RB around the support shafts SS. In this state, the sound-insulating jacket 37 is fixed to the actuator module 21. As shown in Fig. 13, a space SP is defined between the inner surface of the sound-insulating jacket 37 and the outer surface of the actuator module 21. Note that the support shafts SS and rubber RB are not shown in Fig. 13.

[0115] The harness 23 extends from the connection portion CN between the actuator module 21 and the harness 23 through the space SP to the wiring opening OP. Ｗ Extends to wiring opening OP Ｗ 13, the harness 23 extends from the connection portion CN to the wiring opening OP Ｗ , the actuator module 21 and the sound insulating jacket 37 are not in contact with each other.

[0116] In this way, the wiring opening OP Ｗ By arranging the wiring opening OP at a position far from the connection portion CN between the harness 23 and the actuator module 21, the harness 23 extending from the actuator module 21 can be arranged inside the sound insulating jacket 37 over a long distance. Ｗ This allows the length of the harness 23 located between the wiring opening OP to be increased. ＷThis can attenuate the vibration before it reaches the sound-insulating jacket 37, thereby suppressing the transmission of vibration from the actuator module 21 via the harness 23 to the outside of the sound-insulating jacket 37 or to the sound-insulating jacket 37 itself.

[0117] Also, the actuator module 21 and the wiring opening OP Ｗ By reducing the contact between the harness 23 located between the actuator module 21 and the wiring opening OP, it is possible to more effectively attenuate vibrations transmitted through the harness 23. Ｗ By reducing the contact between the harness 23 located between the harness 23 and the sound-insulating jacket 37, the transmission of vibration from the harness 23 to the sound-insulating jacket 37 can be more effectively suppressed.

[0118] In FIG. 12, the connection portion CN is located on the right side of the actuator module 21, and the wiring opening OP Ｗ is located on the left side of the actuator module 21, but is not limited to this. For example, the connection portion CN is located above the actuator module 21, and the wiring opening OP Ｗ may be located below the actuator module 21. Ｗ and the connection portion CN, the actuator module 21 is positioned on the line connecting the wiring opening OP of any form. Ｗ However, the wiring opening OP is located on the opposite side of the connection portion CN between the harness 23 and the actuator module 21 with respect to the actuator module 21. Ｗ This applies to:

[0119] Connection part CN and wiring opening OP Ｗ The harness 23 located between the sound-insulating jacket 37 and the actuator module 21 is arranged so that the harness 23 does not come into contact with either the sound-insulating jacket 37 or the actuator module 21, whether or not vibration from the actuator module 21 is being transmitted to the harness 23. However, this is not limitative. ＷThe harness 23 located between the sound-insulating jacket 37 and the actuator module 21 may come into contact with the sound-insulating jacket 37 and / or the actuator module 21 when vibrations from the actuator module 21 are being transmitted to the harness 23 and / or when vibrations from the actuator module 21 are not being transmitted to the harness 23.

[0120] The connection portion CN is located on one side of the center portion in an arbitrary direction (first direction) of the internal space of the sound insulating jacket 37, and the wiring opening OP is located on the other side of the center portion in the arbitrary direction (first direction). Ｗ Specifically, for example, in FIG. 12 where the connection portion CN is located at the upper right of the sound insulating jacket 37, the wiring opening OP Ｗ may be disposed at the lower right corner of the sound-insulating jacket 37. In this manner, the harness 23 can be disposed inside the sound-insulating jacket 37 over a long distance.

[0121] [Modification 7] In the above embodiment and modifications, as in the sound-insulating jacket 38 shown in FIG. 14(a), a labyrinth-shaped passage is provided inside the sound-insulating jacket, and a wiring opening OP Ｗ may define an entrance and exit to the labyrinth passage.

[0122] The sound-insulating jacket 38 shown in Fig. 14(a) has a flat jacket base 381 and a bathtub-shaped jacket cover 382. In Fig. 14(a), the jacket base 381 is drawn transparently in order to show the inside of the sound-insulating jacket 38. When the jacket cover 382 is fixed to the jacket base 381, a wiring opening OP is formed by a notch NT provided near the upper left end of the jacket base 381 and the rear end of the jacket cover 382. Ｗ is defined.

[0123] 14(a) and 14(b), a first plate portion PL1 extending in a plane perpendicular to the up-down direction, and a second plate portion PL2, a third plate portion PL3, and a fourth plate portion PL4 extending in a plane perpendicular to the left-right direction are provided at the upper left corner of the jacket cover 382. The front ends of the first plate portion PL1 to the fourth plate portion PL4 are connected to a front plate 382a of the jacket cover 382. The rear ends of the first plate portion PL1 to the fourth plate portion PL4 abut against the jacket base 381 when the jacket cover 382 is attached to the jacket base 381.

[0124] The left end of the first plate portion PL1 is connected to the left plate 382c of the jacket cover 382. The lower ends of the second plate portion PL2 and the fourth plate portion PL4 are connected to the first plate portion PL1, and their upper ends face, across a gap, the upper plate 382f of the jacket cover 382. The upper end of the third plate portion PL3 is connected to the upper plate 382f of the jacket cover 382, ​​and their lower end faces, across a gap, the first plate PL1.

[0125] When the jacket cover 382 is attached to the jacket base 381, a labyrinth-shaped passage CH is defined in a space surrounded by the jacket base 381, the front plate 382a and the top plate 382f of the jacket cover 382, ​​and the first plate portion PL1. The labyrinth-shaped passage CH extends from the gap between the second plate portion PL2 and the top plate 382f, through the gap between the third plate portion PL3 and the first plate portion PL1 and the gap between the fourth plate portion PL4 and the top plate 382f, to the wiring opening OP Ｗ The labyrinth-shaped passage CH is a passage that leads from the gap between the second plate portion PL2 and the upper plate 382f to the wiring opening OP Ｗ The harness 23 is bent four times in the path leading to the labyrinth-shaped passage CH. The harness 23 is arranged inside the labyrinth-shaped passage CH and along the labyrinth-shaped passage CH.

[0126] In this way, a labyrinth-shaped passage CH is provided inside the sound-insulating jacket 38, and the wiring opening OP Ｗ By defining the entrance and exit of the labyrinth-shaped passage CH by the ＷThat is, the operating sound of the actuator module 21 must be propagated while being reflected along the bent passages in the labyrinth-shaped passage CH. Ｗ is attenuated before reaching

[0127] The labyrinth-shaped passage CH may have various configurations with any number of bends. For example, in Figures 14(a) and 14(b), either the second plate portion PL2 or the fourth plate portion PL4 may be omitted. The direction in which the passage is bent is arbitrary. Furthermore, the position at which the labyrinth-shaped passage CH is provided is arbitrary.

[0128] [Modification 8] In the above embodiment and modification, the sound-proofing mechanism 30 has a wiring opening OP Ｗ The vehicle may further include a vibration absorbing member disposed between the sound insulating jackets 31, 35, 37, 38 and the harness 23.

[0129] Specifically, for example, a bent cylindrical cap CP shown in FIG. 15 is inserted into the wiring opening OP. Ｗ The harness 23 is attached to the cap CP, and an annular vibration absorbing member DM is attached to the inside of the cap CP. The harness 23 passes through an inner hole of the annular vibration absorbing member DM. The vibration absorbing member DM may be any vibration absorbing member having a vibration absorbing function, such as rubber, sponge, or a gel sheet.

[0130] In this way, the wiring opening OP Ｗ By providing the vibration absorbing members DM between the sound insulating jackets 31, 35, 37, and 38 and the harness 23, the transmission of vibration from the harness 23 to the sound insulating jackets 31, 35, 37, and 38 is suppressed. This makes it possible to more effectively suppress the leakage of the operating noise of the actuator module 21.

[0131] 15 is annular and disposed around the entire circumference of the harness 23, but is not limited to this. The vibration absorbing member DM may have any shape, such as a C-shape or an I-shape. The vibration absorbing member DM may be disposed so that there is no contact between the harness 23 and the sound insulating jackets 31, 35, 37, and 38. Alternatively, the vibration absorbing member DM may be disposed so that there are fewer contact points between the harness 23 and the sound insulating jackets 31, 35, 37, and 38. The cap CP may be omitted.

[0132] [Modification 9] In the above-described embodiment and modifications, a positioning structure for positioning the jacket base and the jacket cover may be provided on each of the jacket base and the jacket cover, as in the sound-insulating jacket 31' shown in Fig. 16. This makes it possible to easily position the jacket base and the jacket cover.

[0133] The sound insulating jacket 31' shown in FIG. 16 has a jacket base 311' and a jacket cover 312'.

[0134] The jacket base 311' has a screw hole th ３１１ The position of the positioning hole AH and the positioning pin AP ３１１ 2B in the above embodiment, except that the jacket base 311 has the same configuration as the jacket base 311 shown in FIG. 2B in the above embodiment.

[0135] Screw hole th ３１１ Four positioning holes AH are provided along the upper and lower sides of the jacket base 311'. One positioning hole AH is provided near the upper and lower sides of the jacket base 311' to the right of the center in the left-right direction of the jacket base 311'. ３１１ are provided on the left side of the center of the jacket base 311' in the left-right direction, near the upper edge and the lower edge of the jacket base 311'.

[0136] In this modification, the positioning holes AH and the positioning pins AP are ３１１The shape of each of the two positioning holes AH is circular, but is not limited to this. By making one of the two positioning holes AH an ellipse with its major axis extending in the vertical direction, good positioning can be achieved even when there are dimensional variations in the jacket base 311′ and / or the jacket cover 312′ due to processing errors or the like.

[0137] In this modification, four screw holes th provided along the upper side of the jacket base 311′ ３１１ , positioning hole AH, and positioning pin AP ３１１ are positioned in a straight line along the left-right direction. Also, four screw holes th provided along the lower side of the jacket base 311′ ３１１ , positioning hole AH, and positioning pin AP ３１１ are located on a straight line along the left-right direction.

[0138] The jacket cover 312' has two positioning holes AH on the flange portion 312F. ３１２ , two through holes TH ３１２ , and four notches nt ３１２ The cylindrical portion CL has an opening OP. ３１２ The jacket cover 312 has the same configuration as the jacket cover 312 of the above embodiment, except that it extends rearward from the

[0139] Positioning hole AH ３１２ are provided on the left side of the center of the jacket cover 312' in the left-right direction, one on each of the upper flange portion 312F and the lower flange portion 312F. ３１２ are provided on the upper flange portion 312F and the lower flange portion 312F, respectively, on the right side of the center portion in the left-right direction of the jacket base 312′. ３１２ are provided in the upper flange portion 312F and the lower flange portion F312, and two positioning holes AH ３１２ and through hole TH ３１２ The cylindrical portion CL is provided with an opening OP ３１２ It extends rearward in the front-rear direction from the outer periphery of the

[0140] A base 10' shown in Figure 16 can be used together with the sound-insulating jacket 31'. The base 10' has the same structure as the base 10 of the above embodiment, except that the positioning pin AP is provided at a position corresponding to the position of the positioning hole AH of the jacket base 311'. The battery case 13 is not shown in Figure 16.

[0141] When the jacket cover 312' is attached to the jacket base 311', the rear surface of the flange portion 312F is brought into close contact with the front surface of the jacket base 311'. At this time, the positioning pin AP ３１１ The positioning holes AH of the jacket cover 312 are ３１２ The jacket cover 312' is fixed to the jacket base 311' by inserting the screw holes th ３１２ and the screw holes th at the four corners of the jacket base 311' ３１１ This is done by screwing in place.

[0142] In a state where the jacket cover 312′ is fixed to the jacket base 311′, the positioning hole AH of the jacket base 311′ and the through hole TH of the jacket cover 312′ are ３１２ The two screw holes th arranged near the center of the upper side of the jacket base 311′ overlap. ３１１ are two notches nt provided on the upper flange portion 312F of the jacket cover 312'. ３１２ The two screw holes th disposed near the center of the lower side of the jacket base 311' are located inside the ３１１ are two notches nt provided in the lower flange portion 312F of the jacket cover 312'. ３１２ are located inside each other.

[0143] When attaching the sound-insulating jacket 31' to the base 10', the positioning pins AP of the base 10' are inserted into the positioning holes AH of the jacket base 311' to position the sound-insulating jacket 31' and the base 10'. ３１２The positioning pin AP can be seen through the

[0144] The sound-insulating jacket 31' is fixed to the base 10' by four screw holes th disposed near the center of the upper and lower sides of the jacket base 311'. ３１１ At this time, the jacket cover 312' is attached by a screw or the like (not shown). ３１２ Screw fastening can be performed through this.

[0145] Positioning pin AP of jacket base 311' ３１１ and the positioning hole AH of the jacket cover 312 ３１２ are examples of positioning structures. However, the positioning structure may be of any form, such as an opening provided in the jacket base 311′ and a protrusion provided in the jacket cover 312′ to be inserted into the opening. Alternatively, a recess may be provided instead of an opening. The number of positioning structures provided in the jacket base and the number of positioning structures provided in the jacket cover may be one or any multiple. For example, by making the positioning structure provided in one of the jacket base and the jacket cover a protrusion of any polygonal prism shape and making the positioning structure provided in the other of the jacket base and the jacket cover a recess of a shape corresponding to the polygonal prism, good positioning can be achieved even when the jacket base and the jacket cover have a single positioning structure. Furthermore, the positioning structure may be a structure that uniquely positions the jacket case and the jacket cover, or a structure that assists in unique positioning.

[0146] In this modification, when the sound insulating jacket 31′ is attached to the base 10′, the positioning pins AP of the base 10′ inserted into the positioning holes AH of the jacket base 311′ are inserted into the through holes TH of the jacket cover 312′. ３１２ In this way, by providing an opening in the jacket cover for visually checking the protrusion of the base (attachment object) inserted into the opening of the jacket base, it is possible to easily determine the positioning between the sound insulating jacket and the base. In this modified example, the through hole TH ３１２The through hole TH of the jacket cover 312′ has the same shape as the positioning hole AH when viewed in the front-rear direction, but is not limited to this. ３１２ may be omitted.

[0147] In this modification, the jacket cover 312′ has a notch nt ３１２ , the sound-insulating jacket 31' can be screwed to the base 10' inside the outer edge of the jacket cover 312 when viewed in the front-to-rear direction. This allows the jacket base 311 to be made smaller, and therefore the sound-insulating jacket 31' can also be made smaller.

[0148] [Modification 10] In the above embodiment and modifications, a cylindrical portion may be provided that extends from the opening of the sound-insulating jacket into the interior of the sound-insulating jacket, and the bushing may be disposed inside the sound-insulating jacket. This can prevent the bushing from falling off. Also, the cylindrical portion and the bushing may define a labyrinth structure. This can more effectively prevent the leakage of operating noise from the actuator module 21. Specifically, for example, the following configurations are possible.

[0149] As described above, the sound-insulating jacket 31' shown in FIG. 16 has an opening OP of the jacket cover 312'. ３１２ 17A shows a sound insulating jacket 31' having such a structure, in which a bushing 38 is disposed inside the sound insulating jacket 31'.

[0150] The bushing 38 has an annular portion AN, an inner cylindrical portion IC extending from the inner periphery of the annular portion AN along one side of the axial direction of the annular portion AN, and an outer cylindrical portion OC extending from the outer periphery of the annular portion AN along one side of the axial direction of the annular portion AN. The central axes of the annular portion AN, the inner cylindrical portion IC, and the outer cylindrical portion OC are all coincident. The length of the outer cylindrical portion OC is greater than the length of the inner cylindrical portion IC.

[0151] The bushing 38 is attached to the input shaft S2 of the actuator module 21 by the inner peripheral surface IC of the inner cylindrical portion IC. ＩＮ is the outer circumferential surface S2 of the input shaft S2 ＯＵＴWhen the actuator module 21 to which the bushing 38 is attached is housed inside the sound-insulating jacket 31', the bushing 38 is located inside the sound-insulating jacket 31'.

[0152] In this state, the area near the front end of the inner cylindrical portion IC of the bushing 38 and the rear end CL of the cylindrical portion CL of the jacket cover 312′ ＲＥ The outer cylindrical portion OC of the bushing 38 and the cylindrical portion CL of the jacket cover 312′ overlap with each other when viewed in the radial direction of the input shaft S2.

[0153] In the radial direction of the input shaft S2, the outer peripheral surface IC of the inner cylindrical portion IC of the bushing 38 ＯＵＴ and the inner circumferential surface CL of the cylindrical portion CL of the jacket cover 312′ ＩＮ The inner peripheral surface OC of the outer cylindrical portion OC of the bushing 38 faces the inner peripheral surface OC of the outer cylindrical portion OC of the bushing 38 with a gap therebetween. ＩＮ and the outer circumferential surface CL of the cylindrical portion CL of the jacket cover 312′ ＯＵＴ are opposed to each other with a gap therebetween.

[0154] In the axial direction (front-rear direction) of the input shaft S2, the rear end portion CL of the cylindrical portion CL of the jacket cover 312′ ＲＥ and the front surface AN of the annular portion AN of the bush 38 ＦＲ The rear surface 312' of the jacket cover 312' faces the rear surface 312' of the jacket cover 312' with a gap G1 therebetween. ＲＥ and the front end portion OC of the outer cylindrical portion OC of the bushing 38 ＦＲ The gap G1 is larger than the gap G2.

[0155] In this modified example, a labyrinth structure is defined by the cylindrical portion CL and the bushing 38, which face each other with a gap therebetween, thereby effectively suppressing leakage of the operating noise of the actuator module 21.

[0156] In this modification, the gap G1 between the cylindrical portion CL and the annular portion AN, which face each other in the front-rear direction, is larger than the gap G2 between the jacket cover 312′ and the outer cylinder portion OC, which face each other in the front-rear direction. This has the following effect.

[0157] When the jacket cover 312' is machined to provide the cylindrical portion CL, the rear end CL of the cylindrical portion CL ＲＥ Therefore, if the rear end CL of the cylindrical portion CL is ＲＥ When the annular portion AN of the bushing 38 abuts against the rear end CL of the cylindrical portion CL, ＲＥ The rear surface 312' of the jacket cover 312' is not flush with the rear surface 312' of the jacket cover 312', which may cause the bushing 38 to tilt. ＲＥ It is relatively easy to make the surface flat.

[0158] Therefore, the gap G1 is set larger than the gap G2, and when the bushing 38 moves in the front-rear direction, the outer cylindrical portion OC is brought into contact with the rear surface 312' of the jacket cover 312' before the cylindrical portion CL of the jacket cover 312' comes into contact with the annular portion AN. ＲＥ By bringing the jacket cover 312' into contact with the bush 38, it is possible to prevent the central axis of the bush 38 from being displaced from the rotation axis AX of the input shaft S2 due to contact between the jacket cover 312' and the bush 38.

[0159] In the above description, a cylindrical portion extending into the sound-insulating jacket is provided at the opening of the jacket cover, and a bushing is disposed inside the sound-insulating jacket around the input shaft S2, but this is not limiting. A cylindrical portion extending into the sound-insulating jacket may be provided at the opening of the jacket base, and a bushing may be disposed inside the sound-insulating jacket around the output shaft S1.

[0160] In addition, any bushing of any shape that is placed inside the sound-insulating jacket and defines a labyrinth structure between the bushing and a cylindrical portion that extends from the opening of the sound-insulating jacket into the interior of the sound-insulating jacket can be used in any installation manner.

[0161] [Modification 11] In the above-described embodiment and modifications, the bushing may be attached to the sound-insulating jacket so as to be movable both in a plane including the opening of the sound-insulating jacket and in a direction perpendicular to the plane. This allows the position of the bushing to be adjusted during assembly, facilitating the process of passing the output shaft S1 and / or the input shaft S2 of the actuator module 21 through the bushing. Specifically, the following configurations are possible, for example.

[0162] 17(b) shows the state in which a bushing 39 is arranged inside the sound-insulating jacket 31' in the sound-insulating jacket 31'. The bushing 39 has an annular portion AN, an inner cylindrical portion IC extending from the inner periphery of the annular portion AN along one side of the axial direction of the annular portion AN, and an outer cylindrical portion OC extending from the outer periphery of the annular portion AN along one side of the axial direction of the annular portion AN. The central axes of the annular portion AN, the inner cylindrical portion IC, and the outer cylindrical portion OC are all coincident with one another. The length of the inner cylindrical portion IC is greater than the length of the outer cylindrical portion OC. The outer peripheral surface IC of the inner cylindrical portion IC ＯＵＴ , outer surface IC ＯＵＴ A groove SL is provided around the entire periphery.

[0163] The bushing 39 has an annular portion AN located inside the sound-insulating jacket 31' and an inner cylindrical portion IC located in the opening OP of the jacket cover 312'. ３１２ The inner cylindrical portion IC is attached to the jacket cover 312' in a state where it protrudes outside the sound insulating jacket 31' via the outer peripheral surface IC ＯＵＴ An E-ring ER is attached to the groove SL, and a washer WA is provided between the E-ring ER and the jacket cover 312'. The input shaft S2 of the actuator module 21 arranged inside the sound-insulating jacket 31' passes through a central hole in the inner cylindrical portion IC of the bushing 39 and extends to the outside of the sound-insulating jacket 31'.

[0164] In this state, the bushing 39 is axially and radially spaced from the input shaft S2 (i.e., the opening OP ３１２ The movement is possible in both directions (in-plane direction of a plane including the plane and direction perpendicular to the plane).

[0165] Specifically, as shown in FIG. 17B, the outer peripheral surface IC of the inner cylindrical portion IC of the bush 39 ＯＵＴand the inner circumferential surface CL of the cylindrical portion CL of the jacket cover 312′ ＩＮ The inner peripheral surface OC of the outer cylindrical portion OC of the bushing 39 faces the inner peripheral surface OC of the outer cylindrical portion OC of the bushing 39 with a gap therebetween. ＩＮ and the outer circumferential surface CL of the cylindrical portion CL of the jacket cover 312′ ＯＵＴ The inner peripheral surface IC of the inner cylindrical portion IC of the bushing 39 faces the inner peripheral surface IC of the inner cylindrical portion IC of the bushing 39 with a gap therebetween. ＩＮ and the outer peripheral surface S2 of the input shaft S2 of the actuator module 21 ＯＵＴ Therefore, the bushing 39 is movable in the radial direction of the input shaft S2 relative to the actuator module 21 and the sound insulating jacket 31'. ＩＮ and the outer peripheral surface S2 of the input shaft S2 of the actuator module 21 ＯＵＴ may be in contact with each other.

[0166] 17(b), there is a gap between the washer WA and the jacket cover 312' in the front-rear direction. Therefore, the bushing 39 is movable in the axial direction of the input shaft S2 relative to the actuator module 21 and the sound-insulating jacket 31'. Although FIG. 17(b) shows a state in which a gap exists between the washer WA and the jacket cover 312', if a gap exists between the E-ring ER and the washer WA in response to the movement of the bushing 39 and the washer WA, the outer cylindrical portion OC of the bushing 39 will move. ＯＵＴ Front end OC ＦＲ and the rear surface 312' of the jacket cover 312'. ＲＥ There may be a gap between them.

[0167] In the axial direction (front-rear direction) of the input shaft S2, the rear surface 312' of the jacket cover 312' ＲＥ and the front end portion OC of the outer cylindrical portion OC of the bushing 39 ＦＲ and the rear end CL of the cylindrical portion CL of the jacket cover 312′ in a state where they are in contact with each other. ＲＥ and the annular portion AN of the bushing 39 face each other with a gap therebetween. Therefore, as in the tenth modification, the rear end portion CL of the cylindrical portion CL ＲＥ This prevents the bushing 39 from being displaced due to contact between the annular portion AN of the bushing 39 and the bushing 39.

[0168] In this modification, a labyrinth structure is defined by the cylindrical portion CL and the bushing 39, which face each other with a gap therebetween, thereby effectively suppressing leakage of the operating noise of the actuator module 21.

[0169] Although the above description has been given of an embodiment in which the bushing 39 is disposed inside the sound-insulating jacket around the input shaft S2, the present invention is not limited to this. The bushing 39 may also be disposed inside the sound-insulating jacket around the output shaft S1.

[0170] [Other Modifications] In the above embodiment and each modification, the output shaft S1 has an opening OP. ３１１ The input shaft S2 extends to the outside of the sound insulating jacket 31 through the opening OP ３１２ 1000 to the outside of the sound insulating jacket 31. However, this is not limited to this. The output shaft S1 and the input shaft S2 may be long enough to fit inside the sound insulating jacket 31. In this case, the shaft portion formed integrally with the deadbolt movement mechanism or the thumb turn of the door 1000 is inserted into the opening OP ３１１ Or opening OP ３１２ In the present invention, "the output shaft (input shaft) is disposed in the opening" means that the output shaft (input shaft) is located inside the opening when viewed in the axial direction of the output shaft (input shaft).

[0171] In the above embodiment and each of the modified examples, the actuator module 21 does not have to have the input shaft S2.

[0172] In the above embodiment and each modified example, the actuator module 21 may include a status detection sensor (not shown) for detecting the status of the output shaft S1. The status detection sensor may be, for example, a magnetic sensor that detects the position of the driven gear G3 and / or the output gear G4 in the rotational direction. In this case, the controller 212 may control the motor driver 213 based on an external input and an input from the status detection sensor.

[0173] In the above embodiment and modified examples, the arrangement of the plate-shaped protrusions PT1 to PT3 is arbitrary. The plate-shaped protrusions PT2 and PT3 do not have to be rotationally symmetrical with respect to the central axes of the output shaft S1 and the input shaft S2. Furthermore, the plate-shaped protrusions PT2 and PT3 do not have to be line-symmetrical with respect to a line that passes through the central axes of the output shaft S1 and the input shaft S2 and extends in the up-down direction.

[0174] In the actuator module 21 of the above embodiment and each modified example, the controller 212, the motor driver 213, the motor 214, and the power transmission unit 215 are all housed in the housing 211, but this is not limited thereto. The housing 211 may be configured to house at least a part of the motor 214 and / or the power transmission unit 215. Also, in the above embodiment, as shown in FIG. 3, the output gear G4 of the power transmission unit 215 is located through an opening OP of the housing 211. ２１１ and is exposed to the outside. In addition, the output shaft S1 and input shaft S2 of the power transmission unit 215 are located outside the housing 211. In this specification and the present invention, the phrase "the housing houses a certain member" includes both an embodiment in which the entirety of a certain member is housed inside the housing and an embodiment in which a part of a certain member is located outside the housing.

[0175] In the above embodiment and each modified example, the sound-proofing mechanism 30 hermetically surrounds the actuator module 21. In the present invention, "sealedly surrounding" means accommodating the actuator module 21 while leaving only gaps that inevitably occur due to the arrangement of structures for supplying and extracting power and electricity (e.g., wiring, output shaft, etc.). Note that the sound-proofing mechanism 30 does not need to hermetically surround the actuator module 21 if the desired sound-proofing performance can be obtained.

[0176] In the above embodiment and each modified example, the lock system 100 is attached to the mounting surface of the door body 1000M, but this is not limited to this. The entire lock system 100 may be embedded inside the door body 1000M. In this case, the actuator module 21 and the sound insulation mechanism 30 are also embedded inside the door body 1000M.

[0177] In the above embodiment, the lock unit 20 that is sound-insulated by the sound-insulating mechanism 30 may have any configuration.

[0178] In the above embodiments and each modified example, the controller 212 of the lock unit 20 is not an essential component and can be omitted. If the lock unit 20 does not have the controller 212, a control unit external to the lock unit 20 can have the controller and communication module functions, and the control unit and the lock unit 20 can be connected by wire or wirelessly. The control unit can be located, for example, on the base 10 of the lock system 100, or can be located outside the lock system 100. In the above embodiments, the actuator module 21 does not need to have a housing 211.

[0179] In the above embodiment and each modified example, the communication module 22 of the lock unit 20 is not an essential component and may be omitted. If the lock unit 20 does not have the communication module 22, for example, the lock unit 20 may be connected to an external control unit by wire, and the lock unit 20 may control the motor 214 of the actuator module 21 directly or via the controller 212.

[0180] In the above embodiment and each modification, the wiring opening OP Ｗ is not limited to an opening for passing the harness 23. Ｗ may be an opening for any wiring that electrically connects the actuator module 21 to external equipment (power supply, control circuit, etc.).

[0181] In the above embodiments and each modified example, the sound-proofing mechanism according to the present disclosure can be applied to all locking systems that use electrical drive for locking and unlocking. For example, in addition to the exemplary embodiments, the sound-proofing mechanism according to the present disclosure can also be applied to locking mechanisms that have latches. Furthermore, the instruction device that instructs the locking system to lock and unlock may be a card key that can be touched or scanned by a reader separately installed on the door. Furthermore, an instruction device is not required. For example, the sound-proofing mechanism according to the present disclosure can also be applied to locking mechanisms that do not require an instruction device and that are unlocked by entering and authenticating a predetermined authentication number using an operation unit such as a numeric keypad installed on the door.

[0182] In the above embodiment and each modified example, the lock unit 20 uses the motor 214 as a drive unit that outputs power to move the deadbolt 1000B, but this is not limited to this. The lock unit 20 may have any drive unit. Another example of a drive unit is a linear actuator, etc. The power transmission unit 215 may have any configuration depending on the configuration of the drive unit.
