That is, the first impact dispersion portion 28a is provided, for example, at the 3 o'clock side. Further, the second impact dispersion portion 28b is provided, for example, on the 9 o'clock side. For this reason, the deformable body 27 is configured to be held elastically by the first impact dispersion portion 28a and the second impact dispersion portion 28b so as not to rattle in the housing portion 26a of the main body portion 26. ing.

  That is, as shown in FIGS. 6B and 7, the deformable body 27 is urged counterclockwise by the first impact dispersion portion 28a on the 3 o'clock side, and the second impact dispersion on the 9 o'clock side. By being urged clockwise by the portion 28b, it is elastically held in the accommodating portion 26a of the main body portion 26 so that there is no rattling between the circumferential direction and the axial direction of the deformable body 27. It is configured as follows.

  In this case, as shown in FIGS. 5 to 7, the first impact dispersion portion 28 a is configured such that the groove inclined portion 31 a of the dispersion groove portion 31 that displaces the displacement portion 32 in a direction different from the impact direction is the circumference of the deformable body 27. For example, in FIG. 5B, it is configured to be inclined so as to gradually rise toward the 12 o'clock side (oblique left upper side in FIG. 7) positioned in the counterclockwise direction in FIG. .

  Further, as shown in FIGS. 6 and 7, the first impact dispersion portion 28a is configured such that when the deformable body 27 receives an impact from the outside, the displacement inclined portion 32a of the displacement portion 32 becomes the groove inclined portion 31a. And is displaced while sliding toward one side in the circumferential direction, for example, the 12 o'clock side (oblique left upper side in FIG. 7) positioned in the counterclockwise direction in FIG. 6B.

  On the other hand, as shown in FIG. 5 to FIG. 7, the second impact dispersion portion 28 b includes a groove inclined portion 31 a of the dispersion groove portion 31 that displaces the displacement portion 32 in a direction different from the impact direction, and the circumferential direction of the deformable body 27. For example, in FIG. 5B, it is inclined and provided so as to gradually compete toward the 12 o'clock side (oblique left upper side in FIG. 7) positioned in the clockwise direction in FIG. Yes.

  Further, as shown in FIGS. 6 and 7, the second impact dispersion portion 28b has a displacement inclined portion 32a of the displacement portion 32 along the groove inclined portion 31a when the deformable body 27 receives an impact from the outside. Thus, it is configured to be displaced while sliding toward the side opposite to one side in the circumferential direction, for example, the 12 o'clock side (oblique left upper side in FIG. 7) positioned in the clockwise direction in FIG. 6B. .

  In this case, as shown in FIGS. 4 and 6, the plurality of slit groove portions 33a and 33b are positioned between the displacement portion 32 of the first impact dispersion portion 28a and the displacement portion 32 of the second impact dispersion portion 28b.

  That is, among the plurality of slit groove portions 33a and 33b, a part of the slit groove portions 33a is formed by the displacement portion 32 of the first impact dispersion portion 28a and the second impact dispersion portion 28b as shown in FIG. It is provided on the circumference on the 12 o'clock side located between the displacement part 32. In addition, among the plurality of slit groove portions 33a and 33b, the other part of the slit groove portions 33b is located between the displacement portion 32 of the first impact dispersion portion 28a and the displacement portion 32 of the second impact dispersion portion 28b. It is provided on the circumference of the 6 o'clock side.

  Thereby, as shown in FIG. 6B and FIG. 7, the deforming body 27 has an impact force caused by the first impact dispersing portion 28 a on one side in the circumferential direction of the deforming body 27, for example, in the counterclockwise direction. Is distributed toward the 12 o'clock side (upper side in FIG. 7), so that the slit groove 33a located in the dispersion direction (12 o'clock direction) is deformed in the direction of contraction in the circumferential direction. Yes.

  Further, as shown in FIG. 6B and FIG. 7, the deformation body 27 has an impact force caused by the first impact dispersion portion 28a on one side in the circumferential direction of the deformation body 27, for example, in the counterclockwise direction. Is distributed toward the 12 o'clock side (upper side in FIG. 7) located at, so that the slit groove portion 33b on the opposite side, for example, 6 o'clock side located in the clockwise direction, extends in the circumferential direction. It is comprised so that it may deform | transform into.

  On the other hand, as shown in FIGS. 6B and 7, the deformable body 27 has an impact force which is opposite to one side in the circumferential direction of the deformable body 27 by the second impact dispersion portion 28 b, for example, a watch By being dispersed toward the 12 o'clock side located in the rotation direction, the slit groove portion 33a located in the dispersion direction (12 o'clock direction) is deformed in a direction contracting in the circumferential direction.

  Further, as shown in FIGS. 6B and 7, the deformable body 27 has an impact force which is opposite to one side in the circumferential direction of the deformable body 27, for example, a repulsive force by the second impact dispersion portion 28 b. By being dispersed toward the 6 o'clock side positioned in the clockwise direction, the slit groove portion 33b on the side opposite to this dispersing direction, for example, the 6 o'clock side positioned in the clockwise direction, is deformed in a direction to expand in the circumferential direction. It is configured as follows.

  Therefore, as shown in FIGS. 6B and 7, the deformed body 27 receives an impact from the outside, and the impact force is dispersed by the first impact dispersion portion 28a and the second impact dispersion portion 28b. In this case, the slit groove 33a located in the dispersion direction (12 o'clock side in FIG. 6B) is deformed so as to be contracted, and the deformable bodies 27 located in the dispersion direction (12 o'clock side) are compressed together. It is comprised so that it may deform | transform into.

  Further, as shown in FIGS. 6B and 7, the deformed body 27 receives an impact from the outside, and the impact force is dispersed by the first impact dispersion portion 28a and the second impact dispersion portion 28b. In this case, the slit groove 33b located on the side opposite to the dispersion direction (6 o'clock side in FIG. 6B) is deformed so as to expand, and the deformation located on the side opposite to the dispersion direction (6 o'clock side). It is comprised so that the body 27 may deform | transform in the direction which expand | swells mutually.

Next, the operation of the sensor unit 10 in such a wristwatch will be described.
In the sensor unit 10, even if the sensor unit 12 and the component protection device 13 are configured, the outside of the watch case 1 and the inside of the sensor unit 12 communicate with each other through the flow path, so that the inside of the sensor unit 12 The pressure sensor 14 detects the pressure outside the watch case 1.

  That is, the component protection device 13 includes a protection device 22 and a shock absorber 23, and the shaft is provided at the central portion of the screw member 30 to which the deformable body 27 is deformably attached in the housing portion 26 a of the main body 26 in the shock absorber 23. A flow hole 30d is provided penetrating in the direction, and a flow path is formed through the flow hole 30d to communicate between the outside of the watch case 1 and the inside of the protection device 22.

  In addition, between the inside of the protective device 22 and the inside of the sensor unit 12 by the flow portion 24 b provided in the protective member 24 of the protective device 22 and the flow hole 20 a provided in the pressing member 20 of the sensor unit 12. In addition, a flow path is formed for communicating with each other. For this reason, a flow path is formed by these flow paths for communicating them from the outside of the watch case 1 to the inside of the sensor unit 12.

  Thereby, in the sensor unit 10, pressure such as atmospheric pressure or water pressure outside the watch case 1 is changed to a pressure inside the sensor unit 12 through a flow path formed between the outside of the watch case 1 and the inside of the sensor unit 12. Joins sensor 14. For this reason, the pressure sensor 14 detects the pressure outside the watch case 1.

Next, a case where the sensor unit 10 receives an impact from the outside of the watch case 1 will be described.
In this case, since the shock absorber 23 of the component protection device 13 in the sensor unit 10 is exposed to the outside of the wristwatch case 1, the shock absorber 23 receives an impact from the outside. At this time, the shock is buffered by the shock absorber 23 and the shock that cannot be buffered by the shock absorber 23 is buffered by the protective device 22 of the component protection device 13, thereby favorably protecting the pressure sensor 14 in the sensor unit 12. can do.

  That is, when the shock absorber 23 receives an impact from the outside of the watch case 1, the deformation body 27 of the shock absorber 23 exposed to the outside from the exterior case 3 of the watch case 1 receives the impact. At this time, as shown in FIG. 6B and FIG. 7, the first impact dispersion portion 28 a and the second impact dispersion portion 28, which are the impact dispersion portions 28 provided on the main body portion 26 and the deformable body 27 of the shock absorber 23. The impact force is dispersed in the circumferential direction of the deformable body 27 by the dispersion portion 28b.

  In this case, when the first impact dispersion portion 28a disperses the impact force, as shown in FIGS. 6B and 7, the displacement portion provided on the deformable body 27 of the first impact dispersion portion 28a. 32 displacement inclined portions 32a are located on one side in the circumferential direction along the groove inclined portion 31a of the dispersion groove portion 31 of the main body portion 26, for example, in the counterclockwise direction in FIG. 7 is slid and displaced toward the upper left side.

  At the same time, when the second impact dispersion portion 28b disperses the impact force, as shown in FIG. 6 (b), the displacement portion 32 provided on the deformable body 27 of the second impact dispersion portion 28b. The displacement inclined portion 32a is directed to the opposite side to one side in the circumferential direction along the groove inclined portion 31a of the dispersion groove portion 31 of the main body portion 26, for example, toward the 12 o'clock side positioned in the clockwise direction in FIG. Slide to displace.

  For this reason, when the impact force is dispersed by the first impact dispersion portion 28a and the second impact dispersion portion 28b, as shown in FIG. 6B, in the dispersion direction (for example, at 12 o'clock). The slit groove portion 33a positioned is deformed so as to be contracted, and the deformable bodies 27 positioned in the dispersion direction (12 o'clock side) are deformed in a compressing direction. At the same time, the slit grooves 33b located on the opposite side (for example, 6 o'clock side) of the dispersion direction are deformed so as to expand, and the deformable bodies 27 located in the direction opposite to the dispersion direction (6 o'clock side) expand each other. Deform in the direction.

  Thereby, the buffer device 23 buffers the impact by dispersing the impact force received by the deformable body 27 in the circumferential direction of the deformable body 27. At this time, the impact dispersing unit 28 cushions the impact, and the second cushioning member 29 of the cushioning device 23 also cushions the impact. In other words, the impact dispersing portion 28 disperses and buffers the impact force in the circumferential force of the deformable body 27, and the impact force in the axial direction of the deformable body 27 that is not dispersed by the impact dispersive portion 28 is reduced. Buffer with For this reason, the shock can be satisfactorily buffered by the shock absorber 23.

  Further, an impact that cannot be completely buffered by the buffer device 23 is further buffered by the protection device 22. At this time, the shock is buffered by the first buffer member 25 of the protection device 22, and when the shock cannot be absorbed by the first buffer member 25, the shock is transmitted to the protection member 24 of the protection device 22. When the frame-like portion 24 a of 24 is pressed against the outer surface of the main body case 2 and is elastically deformed, an impact that cannot be absorbed by the first buffer member 25 is received by the protective member 24. Thereby, it is possible to prevent the sensor unit 12 from receiving an impact.

  That is, the presser member 20 disposed in the frame-like portion 24a of the protection member 24 and the flange portion 17b of the cylindrical member 17 are not subjected to external impact, and thus the pressure sensor 14 of the sensor unit 12 is protected. In addition, the connection failure between the pressure sensor 14 and the timepiece module 6 due to the flexible wiring board 16 can be prevented. At this time, since the flange portion 17b of the cylindrical member 17 is not subjected to external impact, the welded portion such as brazing of the cylindrical member 17 corresponding to the through hole 11 of the main body case 2 is destroyed. Therefore, airtightness is ensured.

  As described above, according to the shock absorber 23 of the component protection device 13 in the sensor unit 10 of the wristwatch, the main body 26 provided with the accommodating portion 26a and the accommodating portion 26a of the main body 26 are disposed outside. By providing an exposed deformable body 27 and an impact dispersion portion 28 that disperses the impact force in the circumferential direction of the deformable body 27 when the deformable body 27 receives an impact from the outside, the impact is reduced. It is possible to provide a buffer that can be efficiently buffered and that is favorable in terms of design and appearance.

  In other words, in the shock absorber 23 of the component protection device 13, when the deformable body 27 receives an impact from the outside, the impact dispersing portion 28 can disperse the impact force in the circumferential direction of the deformable body 27. Can be efficiently buffered, and the amount of protrusion of the deformable body 27 protruding outward from the main body 26 can be minimized, so that it is possible to provide a design and appearance that is favorable. .

  In this case, the impact dispersion portion 28 is provided on the inner peripheral surface of the housing portion 26 a of the main body portion 26, and on the outer peripheral surface of the deformable body 27. And a displacement portion 32 disposed so as to be displaceable in the circumferential direction. When the deformation body 27 receives an impact from the outside, the displacement portion 32 of the deformation body 27 in the dispersion groove portion 31 of the main body portion 26 is provided. Can be displaced in the circumferential direction of the deformable body 27, whereby the shock can be buffered efficiently and reliably.

  Further, in the shock absorber 23, a groove inclined portion 31 a that displaces the displacement portion 32 in a direction different from the impact direction is provided in the dispersion groove portion 31 so as to be inclined along the circumferential direction of the deformable body 27. In the state where the displacement inclined portion 32a is slidably pressed against the groove inclined portion 31a and is slidably provided along the groove inclined portion 31a, the deformable body 27 is impacted from the outside. When received, the displacement portion 32 of the deformable body 27 can be reliably and satisfactorily displaced in the circumferential direction of the deformable body 27 in the dispersion groove portion 31 of the main body portion 26.

  That is, in the shock absorber 23, when the deformable body 27 receives an impact from the outside, the displacement inclined portion 32a of the displacement portion 32 is slid in the circumferential direction of the deformable body 27 along the groove inclined portion 31a of the dispersion groove portion 31. Therefore, the displacement portion 32 of the deformable body 27 can be reliably and well displaced in the circumferential direction of the deformable body 27 within the dispersion groove portion 31 of the main body portion 26, thereby buffering the impact well. be able to.

  Further, in this shock absorber 23, when the impact dispersing portion 28 disperses the impact force in the circumferential direction of the deformable body 27, a plurality of deformation groove portions for deforming the deformable body 27 in the circumferential direction are provided. Since the slit groove portions 33a and 33b are provided in the deformable body 27, the plurality of slit groove portions 33a and 33b can be deformed in the circumferential direction of the deformable body 27 in accordance with the impact force. Since the deformable body 27 can be deformed in the circumferential direction in accordance with the deformation of 33a and 33b, the shock can be buffered reliably and satisfactorily.

  In this case, when the deformable body 27 receives an impact from the outside, the impact disperser 28 includes the first impact disperser 28a that displaces the deformable body 27 to one side in the circumferential direction, and the deformable body 27. And a second impact dispersion portion 28b that is displaced to the opposite side in the circumferential direction, so that when the deformable body 27 receives an impact from the outside, the first impact dispersion portion 28a The deformable body 27 can be dispersed toward one side (for example, counterclockwise direction) in the circumferential direction, and the deformable body 27 is opposite to the one side in the circumferential direction by the second impact dispersion portion 28b. It can be distributed toward the side (for example, clockwise direction).

  Further, the plurality of slit groove portions 33a and 33b are provided on one circumference of the deformable body 27 located between the first impact dispersion portion 28a and the second impact dispersion portion 28b and the other circle opposed thereto. When the deformable body 27 is dispersed toward one side in the circumferential direction (for example, counterclockwise direction) by the first impact dispersion portion 28a by being provided respectively on the circumference, the The slit groove 33a located in the dispersion direction (for example, 12:00) can be deformed so as to shrink in the circumferential direction, and the slit groove 33b located on the opposite side (for example, 6 o'clock) to the circumferential direction. Can be deformed to spread.

  Similarly, when the deformed body 27 is dispersed toward the opposite side (for example, clockwise direction) in the circumferential direction by the second impact dispersion portion 28b, the dispersion direction (for example, 12 o'clock side) ) And the slit groove 33b located on the opposite side (for example, 6 o'clock side) of the dispersion direction can be deformed so as to expand in the circumferential direction. Can do.

  Thereby, in this shock absorber 23, when the impact force is dispersed by the first impact dispersion portion 28a and the second impact dispersion portion 28b, the slit groove portion 33a located in the dispersion direction (for example, 12 o'clock side). Can be deformed in such a manner that the deformable body 27 positioned in the dispersion direction (12 o'clock side) can be deformed in the compression direction, and the slit groove portion 33b located on the opposite side (for example, 6 o'clock side) of the dispersion direction. Can be deformed in the direction in which the deformable body 27 located in the opposite direction (6 o'clock side) to the expansion direction is expanded, thereby dispersing the impact in the circumferential direction with certainty and It can buffer well.

  Further, in the shock absorber 23, a second shock absorbing member 29 is disposed between the main body portion 26 and the deformable body 27 to buffer the shock in the axial direction of the deformable body 27 when the shock dispersive portion 28 buffers the shock. As a result, when the deformable body 27 receives an impact from the outside and the impact force is distributed to the circumferential force of the deformable body 27 by the shock dispersive section 28 and buffered, the shock dispersive section 28 disperses the impact force. The impact force in the axial direction of the deformed body 27 that is not applied can be buffered by the second buffer member 29, so that the shock can be buffered reliably and satisfactorily.

  Further, the shock absorber 23 includes a screw member 30 that is an attachment member for attaching the deformable body 27 in a deformable state in the accommodating portion 26 a of the main body 26. It can be satisfactorily attached to the housing portion 26a of the main body portion 26 in a deformable state.

  That is, since the screw member 30 includes the screw part 30a, the head part 30b, the neck lower part 30c, and the flow hole 30d, the head part 30b is disposed inside the deformable body 27, and the screw part 30a is disposed in the main body part 26. The deformation portion 27 can be securely attached to the main body portion 26 in a deformable state by being screwed into the screw hole 26c, and the circulation hole 30d allows the outside of the watch case 1 and the inside of the protection device 22 to be attached. Can be communicated.

  In this case, the screw member 30 can be inserted into the screw insertion hole 27a of the deformable body 27 and the inside of the second buffer member 29 to be brought into contact with the bottom of the main body portion 26. Thus, the deformable portion 27 can be attached in the accommodating portion 26a of the main body portion 26, so that the deformable body 27 can be attached in the accommodating portion 26a of the main body portion 26 in a deformable state by the neck lower portion 30c.

  Further, when the deformable portion 27 is attached in the housing portion 26a of the main body portion 26, the screw member 30 causes the deformable body 27 to be attached to the main body portion 26 by the first impact dispersive portion 28a and the second impact dispersive portion 28b. Therefore, when the deformable body 27 receives an impact from the outside, the deformable body 27 can be deformed reliably and satisfactorily.

  By the way, the wristwatch component protection device 13 includes a protection device 22 that covers and protects the sensor unit 12 provided in the wristwatch case 1, and a buffer device 23 that buffers an impact on the protection device 22. Thus, even if an impact is received from the outside, the impact can be buffered by the shock absorber 23, and the sensor unit 12 can be reliably and satisfactorily protected by the protection device 22.

  That is, in the component protection device 13, the protection device 22 includes a protection member 24 that is fixed to the outer surface of the watch case 1 so as to cover the sensor unit 12, and a first buffer member 25 that is disposed on the outer surface of the protection member 24. , The shock that cannot be completely buffered by the shock absorber 23 can be buffered by the first buffer member 25, and when the shock cannot be absorbed by the first buffer member 25, the protective member 24. By being pressed against the outer surface of the wristwatch case 1 and elastically deforming, the impact that cannot be absorbed by the first buffer member 25 can be reliably received by the protective member 24.

  For this reason, according to this component protection device 13, since the sensor unit 12 does not receive an external impact, the pressure sensor 14 of the sensor unit 12 can be reliably and satisfactorily protected and flexible wiring can be provided. Connection between the pressure sensor 14 and the timepiece module 6 by the substrate 16 can surely prevent connection failure due to impact.

  Further, in this component protection device 13, pressure such as atmospheric pressure or water pressure outside the watch case 1 is changed to a pressure inside the sensor unit 12 through a flow passage formed between the outside of the watch case 1 and the inside of the sensor unit 12. By adding to the sensor 14, the pressure sensor 14 can accurately and satisfactorily detect the pressure outside the watch case 1.

By being dispersed toward the hour side (lower side in FIG. 12), the deformation groove portion 55a positioned in the dispersion direction (3 o'clock direction) is deformed in a direction of contracting in the circumferential direction.

  Further, as shown in FIGS. 11 and 12, the deformable body 50 has an impact force that is positioned on one side in the circumferential direction of the deformable body 50, for example, in the clockwise direction, by the first impact dispersion portion 51a. By being dispersed toward the hour side, the deformation groove portion 55b on the side opposite to the dispersion direction, for example, the 9 o'clock side located in the counterclockwise direction, is deformed in a direction to expand in the circumferential direction. .

By being dispersed toward the 3 o'clock side located at, the deformation groove portion 55b located on the opposite side (9 o'clock side) to the dispersion direction is deformed in the direction of expanding in the circumferential direction.

  For this reason, as shown in FIGS. 11 and 12, the deformable body 50 receives an impact from the outside, and the impact force is dispersed by the first impact dispersion portion 51a and the second impact dispersion portion 51b. Further, the deformation groove portion 55a located in the dispersion direction (3 o'clock side) is deformed so as to be contracted, and the deformable bodies 50 located in the dispersion direction (3 o'clock side) are deformed in a compressing direction. .

  Further, as shown in FIGS. 11 and 12, the deformable body 50 receives an impact from the outside, and when the impact force is dispersed by the first impact dispersion portion 51a and the second impact dispersion portion 51b. The deformation groove portion 55b located on the opposite side (9 o'clock side) to the dispersion direction is deformed so as to expand, and the deformable bodies 27 located in the opposite direction (9 o'clock side) to the dispersion direction are deformed in the direction of expansion.

  In this case, as shown in FIGS. 9 to 11, the spring member 49 of the operation member 41 is slightly compressed and deformed when the shock absorber 42 receives an external shock, and the shock absorber 42 receives the external shock. When buffering, the spring force is set slightly stronger so that the shock absorber 42 can cushion the shock with almost no deformation.

Next, the operation of the switch device 9 in such a wristwatch will be described.
In the switch device 9, in the normal state, the operation member 41 is pushed out of the watch case 1 by the spring force of the spring member 49, and the head 46 is exposed to the outside from the protective hole 45 of the exterior case 3. The retaining member 47 of the shaft portion 44 is in contact with the inner peripheral surface of the main body case 2. Thus, in the switch device 9, the inner end portion of the shaft portion 44 is separated from the switch portion 6 a provided in the timepiece module 6 in the main body case 2, and the switch portion 6 a is in an off state.

  Further, in this switch device 9, when the head portion 46 of the operation member 41 exposed to the outside from the protective hole 45 of the outer case 3 is pushed against the spring force of the spring member 49, the shaft portion 44 is prevented from being detached. The member 47 is separated from the inner peripheral surface of the main body case 2, and the inner end portion of the shaft portion 44 is pushed into the main body case 2. As a result, in the switch device 9, the inner end portion of the pressed shaft portion 44 presses the switch portion 6 a of the timepiece module 6, and the switch portion 6 a is turned on.

Next, a case where the switch device 9 receives an impact from the outside will be described.
In this case, the spring member 49 of the operation member 41 is slightly compressed and deformed when the shock absorber 42 receives an external shock, but is almost completely deformed while the shock absorber 42 is buffering the external shock. The spring force is set slightly stronger so that an external impact is buffered by the shock absorber 42 without being deformed.

  Therefore, the switch device 9 is provided on the head 46 of the operation member 41 and the inner end of the shaft portion 44 of the operation member 41 even when the shock absorber 42 exposed to the outside of the watch case 1 receives an impact from the outside. Since the portion does not protrude greatly into the main body case 2, the switch portion 6a of the timepiece module 6 in the main body case 2 is not pressed by the inner end portion of the shaft portion 44, and the switch portion 6a is turned off. maintain.

  Thus, when the shock absorber 42 receives an impact from the outside, the deformable body 50 of the shock absorber 42 exposed to the outside from the exterior case 3 of the watch case 1 receives the shock. At this time, the impact force is applied to the deformation body 50 by the first impact dispersion section 51a and the second impact dispersion section 51b, which are the impact dispersion sections 51 provided on the head 46 and the deformation body 50 of the operation member 41. Distributed in the circumferential direction.

  In this case, when the first impact dispersion portion 51a disperses the impact force, the groove inclined portion 54a of the dispersion groove portion 54 provided in the deformable body 50 of the first impact dispersion portion 51a is provided in the head 46. The displacement portion 53 is slid and displaced along the displacement slope portion 53a toward one side in the circumferential direction, for example, the 3 o'clock side (in FIG. 12, diagonally lower left side) positioned in the clockwise direction.

  At the same time, when the second impact dispersion portion 51 b disperses the impact force, the groove inclined portion 54 a of the dispersion groove portion 54 provided in the deformable body 50 of the second impact dispersion portion 51 b is applied to the head 46. Slide along the displacement inclined portion 53a of the provided displacement portion 53 toward the side opposite to one side in the circumferential direction, for example, to the 3 o'clock side (in FIG. 12, diagonally lower left) located in the counterclockwise direction. Displace.

  For this reason, when the impact force is dispersed by the first impact dispersion portion 51a and the second impact dispersion portion 51b, the deformation groove portion 55a located in the dispersion direction (for example, 3 o'clock side) is deformed so as to contract. Thus, the deformable bodies 50 positioned in the dispersion direction (3 o'clock side) are deformed in the direction of compressing each other. At the same time, the deformation groove portion 55b located on the opposite side (for example, 9 o'clock side) to the dispersion direction is deformed so as to expand, and the deformable bodies 50 located in the direction opposite to the dispersion direction (9 o'clock side) expand each other. Deform in the direction.

  Thereby, the buffer device 42 buffers the impact by dispersing the impact force received by the deformable body 50 in the circumferential direction of the deformable body 50. At this time, the impact dispersion portion 51 cushions the impact, and the second cushioning member 52 of the cushioning device 42 also cushions the impact. That is, the impact dispersing portion 51 disperses and buffers the impact force in the circumferential force of the deformable body 50, and the axial shock force of the deformable body 50 not dispersed by the impact dispersive portion 51 is absorbed by the second buffer member 52. Buffer. For this reason, the shock can be satisfactorily buffered by the shock absorber 42.

  As described above, when the shock is buffered by the shock absorber 42, the spring member 49 of the operation member 41 is slightly compressed and deformed, and the operation member 41 is pushed into the body case 2 slightly. The inner end portion does not press the switch portion 6 a of the timepiece module 6 in the main body case 2. For this reason, in this switch device 9, it is possible to protect the switch portion 6a of the timepiece module 6 from receiving an impact by buffering the impact with the shock absorber 42 and the spring member 49.

  Thus, according to the shock absorber 42 of the component protection device 40 in the switch device 9 of this wristwatch, the head 46 of the operation member 41 which is the main body provided with the housing 46a, and the housing of the head 46 A deformable body 50 disposed in 46a and exposed to the outside, and an impact dispersing portion 51 that disperses the impact force in the circumferential direction of the deformable body 50 when the deformable body 50 receives an impact from the outside. By providing the same as in the first embodiment, it is possible to buffer the impact efficiently, and it is possible to provide a product that is favorable in terms of design and appearance.

  That is, in the shock absorber 42 of the component protection device 40, when the deformable body 50 receives an impact from the outside, the impact dispersing portion 51 can disperse the impact force in the circumferential direction of the deformable body 50. As in the first embodiment, the impact can be efficiently buffered and the amount of protrusion of the deformable body 50 protruding outward from the head 46 can be minimized, which is preferable in terms of design and appearance. Things can be provided.

  In this case, the impact dispersion portion 51 is provided on the inner peripheral surface of the housing portion 46a of the head portion 46, and on the outer peripheral portion of the deformable body 50, and the displacement portion 53 is disposed inside. Thus, by providing the dispersion groove portion 54 that displaces the deformable body 50 in the circumferential direction by the displacement portion 53, the dispersion groove portion 54 of the deformable body 50 when the deformable body 50 receives an impact from the outside. The displacement portion 53 of the head portion 46 disposed inside can displace the dispersion groove portion 54 in the circumferential direction of the deformable body 50, and thereby shock can be efficiently buffered.

  Further, in the shock absorber 42, the displacement inclined portion 53 a that displaces the dispersion groove portion 54 of the deformable body 50 in a direction different from the impact direction is inclined along the circumferential direction of the deformable body 50. The groove inclined portion 54a that is slidably press-contacted with the displacement inclined portion 53a of the head 46 is displaceable in the circumferential direction along the displacement inclined portion 53a. By being provided, when the deformable body 50 receives an impact from the outside, the dispersive groove portion 54 of the deformable body 50 is reliably and well displaced in the circumferential direction of the deformable body 50 by the displacement portion 53 of the head 46. Can be made.

  That is, in this shock absorber 42, when the deformable body 50 receives an impact from the outside, the groove inclined portion 54a of the dispersion groove portion 54 of the deformable body 50 is moved along the circle of the deformable body 50 along the displacement inclined portion 53a of the head portion 46. Since it can be slid in the circumferential direction, the dispersion groove portion 54 of the deformable body 50 can be reliably and satisfactorily displaced in the circumferential direction of the deformable body 50 by the displacement portion 53 of the head portion 46, thereby improving the impact. Can be buffered.

  Further, in the shock absorber 42, when the impact dispersing portion 51 disperses the impact force in the circumferential direction of the deformable body 50, the plurality of deforming groove portions 55a and 55b for deforming the deformable body 50 in the circumferential direction are provided. By being provided in the deformable body 50, the plurality of deformed groove portions 55a and 55b can be deformed in the circumferential direction of the deformable body 50 in accordance with the impact force, and the deformed groove portions 55a and 55b can be deformed. Accordingly, since the deformable body 50 can be deformed in the circumferential direction, the shock can be satisfactorily buffered.

  In this case, when the deformable body 50 receives an impact from the outside, the impact dispersing portion 51 includes a first impact dispersive portion 51a that displaces the deformable body 50 to one side in the circumferential direction, and the deformable body 50. And a second impact dispersion portion 51b that is displaced to the opposite side in the circumferential direction, so that when the deformable body 50 receives an external impact, the deformation is caused by the first impact dispersion portion 51a. The body 50 can be dispersed toward one side (for example, clockwise direction) in the circumferential direction, and the deformable body 50 is opposite to the one side in the circumferential direction by the second impact dispersion portion 51b ( For example, it can be dispersed in the counterclockwise direction).

  Further, the plurality of deformation groove portions 55a and 55b are provided on one circumference of the deformable body 50 located between the first impact dispersion portion 51a and the second impact dispersion portion 52b and the other circle opposite thereto. When the deformable body 50 is dispersed toward one side in the circumferential direction (for example, clockwise direction) by the first impact dispersion portion 51a, the dispersion is provided. The deformation groove portion 55a located in the direction (for example, 3 o'clock side) can be deformed so as to shrink in the circumferential direction, and the deformation groove portion 55b located on the side opposite to the dispersion direction (for example, 9 o'clock side) It can be deformed to spread.

  Similarly, when the deformable body 50 is dispersed toward the opposite side (for example, counterclockwise direction) in the circumferential direction by the second impact dispersion portion 51b, the dispersion direction (for example, 3 o'clock) The deformation groove portion 55a located on the side) can be deformed so as to shrink in the circumferential direction, and the deformation groove portion 55b located on the side opposite to the dispersion direction (for example, 9 o'clock side) is deformed so as to expand in the circumferential direction. be able to.

Can be deformed in such a way that the deformable body 50 located in the dispersion direction (3 o'clock side) can be deformed in the compression direction, and the deformation groove 55b located on the opposite side (for example, 9 o'clock side) from the dispersion direction. The deformation body 50 located in the direction opposite to the dispersion direction (9 o'clock side) can be deformed in the direction of expansion, thereby dispersing the impact in the circumferential direction with certainty and It can buffer well.

  Further, in the shock absorber 42, a second shock absorbing member 52 for buffering the impact in the axial direction of the deformable body 50 is disposed between the head 46 and the deformable body 50 when the shock dispersive portion 51 buffers the shock. As a result, when the deformable body 50 receives an impact from the outside, and the impact force is distributed to the circumferential force of the deformable body 50 by the shock dispersive part 51 and buffered, the shock dispersive part 51 disperses the shock. The impact force in the axial direction of the deformable body 50 not to be absorbed can be buffered by the second buffer member 52, and thus the impact can be reliably and satisfactorily buffered.
