The cylindrical projecting portion 17 is configured to be disposed in a circular recessed portion 8b provided at the center of the pedestal portion 8a via a waterproof member 18 when the fixing portion 14 is attached to the pedestal portion 8a of the housing body 8.

That is, as shown in fig. 2 to 4, the cylindrical projecting portion 17 is formed so that the outer diameter is smaller than the inner diameter of the recessed portion 8b of the pedestal portion 8a, and when inserted into the recessed portion 8b of the pedestal portion 8a, a gap is provided between the outer peripheral surface of the projecting portion 17 and the inner peripheral surface of the recessed portion 8 b. The waterproof member 18 is a waterproof ring having elasticity such as rubber, and is configured to achieve waterproofing between the convex portion 17 of the fixing portion 14 and the concave portion 8b of the pedestal portion 8a by compressing a gap disposed between the outer peripheral surface of the convex portion 17 and the inner peripheral surface of the concave portion 8 b.

As shown in fig. 3 and 4, the waterproof member 18 is configured to abut against the inner surface of the fixing portion 14 when the fixing portion 14 is fastened and fixed to the pedestal portion 8a by the plurality of screw members 16 in a state of being sandwiched between the outer peripheral surface of the convex portion 17 and the inner peripheral surface of the concave portion 8 b. Thus, the waterproof member 18 is configured to position the lock member 12 with respect to the pedestal portion 8a of the housing main body 8 when abutting against the inner surface of the fixing portion 14.

That is, as shown in fig. 3 and 4, the waterproof member 18 is configured to adjust the attachment state of the fixing portion 14 to the pedestal portion 8a, that is, the inclination in the vertical and horizontal directions of the fixing portion 14 by the elastic force of the waterproof member 18 when the fixing portion 14 is fixed to the pedestal portion 8a by the plurality of screw members 16, and to position the lock member 12 to the pedestal portion 8a so that the through hole 11 of the housing body 8 and the insertion hole 12a of the lock member 12 correspond and coincide on the same axis.

As shown in fig. 2 to 4, the locking portion 15 is a cylindrical portion and is provided in the fixing portion 14 so as to protrude from the center portion thereof toward the outside of the housing main body 8. The locking portion 15 is provided with a male screw portion 15a on the outer peripheral surface. In this case, the insertion hole 12a of the lock member 12 is formed to penetrate through the fixing portion 14 from the inner end surface of the cylindrical projecting portion 17 to the outer end surface of the lock portion 15 with the same inner diameter, and the inner diameter thereof is formed to be the same size as the inner diameter of the large diameter hole 11b of the through hole 11.

As shown in fig. 2 to 4, the operation member 13 includes: a shaft portion 20 slidably and rotatably inserted into the through hole 11 of the housing body 8 and the insertion hole 12a of the lock member 12; and a head portion 21 provided at an outer end portion of the shaft portion 20 and locked to be unlocked by the locking portion 15 of the locking member 12.

As shown in fig. 2 to 4, the shaft portion 20 includes: a cylindrical main shaft 22 slidably and rotatably inserted into the large-diameter hole 11b of the through hole 11 provided in the base portion 8a of the housing main body 8 and the insertion hole 12a of the lock member 12; a slide coupling portion 23 slidably disposed in the main body shaft 22; and an operation shaft 24 as a winding core, which is disposed such that one end is attached to the slide coupling portion 23 and the other end is inserted into the housing main body 8.

As shown in fig. 3 and 4, the main shaft 22 is formed in a cylindrical shape having an outer diameter substantially equal to the inner diameter of the insertion hole 12a of the lock member 12, that is, the inner diameter of the large-diameter hole 11b of the through hole 11 of the pedestal portion 8 a. The main shaft 22 is configured to move in the axial direction with its outer peripheral surface in pressure contact with a plurality of waterproof packings 25 provided on the inner peripheral surface of the lock member 12. Thereby, the outer peripheral surface of the main body shaft 22 and the inner peripheral surface of the insertion hole 12a of the locking member 12 are waterproofed by the waterproof packing 25.

As shown in fig. 3 and 4, the main shaft 22 includes: a polygonal, elliptical or other non-circular hole 22a such as a square or the like provided inside the case body 8; and a circular hole 22b provided on the outer side of the case body 8 and having a size to be inscribed in the non-circular hole 22 a. The non-circular hole 22a is formed in the size inscribed in the small diameter hole 11a of the through hole 11 of the housing main body 8.

As shown in fig. 3 and 4, the circular hole 22b has an inner diameter equal to the inner diameter of the small-diameter hole 11a of the through hole 11 of the housing main body 8. Thus, the main shaft 22 is configured such that the slide coupling portion 23 is slidably disposed in the non-circular hole 22a, and the coil spring 26 is disposed inside the non-circular hole 22a and the circular hole 22b so as to be elastically deformable.

As shown in fig. 3 and 4, the sliding coupling portion 23 is formed in a cylindrical shape having an outer diameter equal to or slightly larger than the inner diameter of the small diameter hole 11a of the through hole 11 of the housing main body 8, and is configured to protrude from and retract into the noncircular hole portion 22a of the main shaft 22 toward the housing main body 8. A stopper 23a is provided at an end of the sliding coupling portion 23, that is, an end of the housing body 8 on the outer side.

As shown in fig. 3 and 4, the stopper portion 23a is formed in a non-circular shape such as an ellipse or an ellipse having the same outer shape as the non-circular hole portion 22a of the main body shaft 22. Thus, the stopper portion 23a slides in the noncircular hole 22a of the main shaft 22 and rotates integrally with the main shaft 22.

As shown in fig. 3 and 4, the stopper portion 23a is configured to come into contact with and come out of contact with a coming-off preventing portion 22c provided at an inner end portion of the non-circular hole portion 22a of the main body shaft 22 on the side of the housing main body 8. Thus, the stopper portion 23a is configured such that the slide coupling portion 23 is not disengaged from the noncircular hole portion 22a of the main shaft 22 toward the housing main body 8 by the disengagement preventing portion 22 c.

In this case, as shown in fig. 3 and 4, a coil spring 26 for biasing the slide coupling portion 23 toward the inside of the housing main body 8 is provided inside the main body shaft 22. The coil spring 26 is disposed inside the main body shaft 22 in a state where one end thereof abuts against the slide coupling portion 23 and the other end abuts against the end of the circular hole 22b of the main body shaft 22 located on the outer side of the housing main body 8 on the depth side.

As shown in fig. 3 and 4, the operating shaft 24 is formed in a rod shape having an outer diameter smaller than the outer diameter of the slide coupling portion 23 slidably disposed in the main shaft 22, that is, the inner diameter of the small-diameter hole 11a of the through hole 11 of the housing main body 8. Therefore, the housing body 8 is formed to be small in the minimum size into which the operation shaft 24 can be inserted by the inner diameter of the small diameter hole 11a of the through hole 11, and the length (thickness) of the housing body 8 in the vertical direction is formed to be short (thin).

As shown in fig. 3 and 4, the operating shaft 24 is configured such that one end is attached to the sliding connection portion 23 and the other end is slidably and rotatably disposed inside the timepiece module 7 in the case body 8 through the small diameter hole 11a of the through hole 11 of the case body 8. Thus, the operation shaft 24 is configured to slide within the watch module 7 in accordance with the sliding operation of the sliding coupling portion 23 disposed in the noncircular hole portion 22a of the main body shaft 22, and to rotate within the watch module 7 in accordance with the rotating operation of the sliding coupling portion 23.

That is, although not shown, the operation shaft 24 is configured to be in a state in which the time adjustment of the timepiece module 7 is possible when the slide coupling portion 23 is pulled out toward the outside of the timepiece case 1 together with the main body shaft 22 and the head portion 21 and slides inside the timepiece module 7, and to be able to perform the time adjustment of the timepiece module 7 when the operation shaft rotates in the timepiece module 7 in accordance with the rotational operation of the slide coupling portion 23 in this state.

On the other hand, as shown in fig. 2 to 4, the head 21 is integrated with the outer end of the main shaft 22. The head 21 is formed in a circular shape having an outer diameter slightly larger than the outer diameter of the central portion of the fixing portion 14 of the lock member 12. That is, the head portion 21 is formed in a circular shape having an outer diameter slightly longer than a length from the center line of the through hole 11 to the lower surface of the housing main body 8 and slightly shorter than a length from the center line of the through hole 11 to the lower surface of the rear cover 6.

As shown in fig. 2 to 4, the head portion 21 is configured to have an annular recess 21a therein, which is larger than the outer diameter of the main shaft 22 and is substantially the same size as the outer diameter of the lock portion 15. In this case, the ring-shaped cushion material 27 is disposed on the depth side in the recess 21a of the head 21 in a state of abutting against the inner end surface of the recess 21a on the depth side.

As shown in fig. 3 and 4, a female screw portion 21b that is screwed into the male screw portion 15a of the locking portion 15 is provided on the inner peripheral surface of the recess 21a of the head 21. Thus, the head 21 is configured such that the female screw portion 21b is screwed with the male screw portion 15a of the locking portion 15 of the locking member 12 when rotated in one direction in a state of being pushed into the housing main body 8.

As shown in fig. 3 and 4, the head 21 is configured to be locked by the locking portion 15 in a state where the cushioning material 27 interposed between the locking portion 15 and the inner end surface of the recess 21a of the head 21 is elastically deformed when the internal thread portion 21b is screwed and fastened to the external thread portion 15a of the locking portion 15 of the locking member 12. The female screw portion 21b of the head 21 and the male screw portion 15a of the lock portion 15 constitute a lock mechanism.

Thus, as shown in fig. 4, in the operating member 13, in the normal state, the operating shaft 24 is stopped in the timepiece module 7, the slide coupling portion 23 is pushed out toward the case body 8 from inside the noncircular hole portion 22a of the body shaft 22, the body shaft 22 is pushed out of the case body 8 by the spring force of the coil spring 26, and the stopper portion 23a of the slide coupling portion 23 abuts against the disengagement prevention portion 22c of the body shaft 22.

In addition, when the head 21 is pushed into the housing main body 8 and locked in the normal state shown in fig. 4, the main body shaft 22 slides together with the head 21 against the elastic force of the coil spring 26, and the slide coupling portion 23 is pushed into the noncircular hole 22a of the main body shaft 22 in accordance with the sliding.

As shown in fig. 4, the operating member 13 is configured such that, in a state where the slide coupling portion 23 is pushed into the noncircular hole portion 22a of the main body shaft 22, when the head 21 is rotated in one direction and the female screw portion 21b of the head 21 is screwed with the male screw portion 15a of the lock member 12, the main body shaft 22 slides toward the inside of the housing main body 8 against the spring force of the coil spring 26.

In this case, as shown in fig. 3 and 4, when the main body shaft 22 slides toward the inside of the case body 8 against the elastic force of the coil spring 26 as the female screw portion 21b of the head 21 is screwed with respect to the male screw portion 15a of the lock member 12, the slide coupling portion 23 is gradually pushed into the noncircular hole portion 22a in the main body shaft 22 as the main body shaft 22 slides by the operating shaft 24 in the state of being restrained in the timepiece module 7, and the restraining portion 23a is gradually separated from the coming-off preventing portion 22c of the main body shaft 22.

As shown in fig. 3, when the head 21 is rotated in one direction, the stopper 23a of the slide coupling portion 23 rotates together with the main body shaft 22 in accordance with the rotation of the head 21, the operation shaft 24 rotates in accordance with the rotation of the slide coupling portion 23, and the female screw portion 21b of the head 21 continues to be screwed to the male screw portion 15a of the lock member 12, whereby the head 21 is locked by the lock portion 15.

On the other hand, as shown in fig. 3 and 4, when the head 21 is rotated in the direction opposite to the one direction and the female screw 21b is disengaged from the male screw 15a of the locking portion 15, the locking of the female screw 21b with respect to the male screw 15a is released, and the main body shaft 22 is pushed out toward the outside of the wristwatch case 1 together with the head 21 by the elastic force of the coil spring 26 in the main body shaft 22.

That is, as shown in fig. 4, when the head 21 is rotated in the opposite direction to loosen the threaded engagement of the female screw portion 21b of the head 21 with the male screw portion 15a of the lock member 12 and unlock the head 21 by the lock portion 15, the operation member 13 is configured such that the body shaft 22 is gradually pushed out toward the outside of the housing body 8 together with the head 21 by the spring force of the coil spring 26, the slide coupling portion 23 is gradually pulled out from the noncircular hole portion 22a of the body shaft 22, and the stopper portion 23a is gradually brought close to the coming-off preventing portion 22 c.

In this case, as shown in fig. 4, when the female screw portion 21b of the head 21 is disengaged from the male screw portion 15a of the lock member 12 and the head 21 is unlocked by the lock portion 15, the main body shaft 22 is pushed out toward the outside of the housing main body 8 together with the head 21 by the spring force of the coil spring 26, the slide coupling portion 23 is pulled out from the noncircular hole portion 22a of the main body shaft 22, and the stopper portion 23a abuts against the stopper portion 22c of the main body shaft 22.

Further, as shown in fig. 4, the operation member 13 is configured such that, in a state where the main body shaft 22 is pushed out toward the outside of the case body 8 together with the head portion 21 by the spring force of the coil spring 26 and the slide coupling portion 23 abuts against the stopper portion 22c of the main body shaft 22, when the head portion 21 is further pulled out to the outside of the case body 8, the operation shaft 24 of the operation member 13 slides in the direction of being pulled out within the timepiece module 7 together with the main body shaft 22 and the operation shaft 24 rotates within the timepiece module 7 in accordance with the rotational operation of the head portion 21 of the operation member 13.

That is, the operation member 13 is configured to be able to correct the time of the timepiece module 7 when the operation shaft 24 is further pulled out and slid inside the timepiece module 7 in a state where the lock of the head portion 21 by the lock portion 15 is released, and to be able to correct the time of the timepiece module 7 when the operation shaft 24 is rotated in the timepiece module 7 in accordance with the rotational operation of the head portion 21 in this state.

Next, the operation of the switch device 4 of the wristwatch will be described.

When assembling the switchgear 4, first, the lock member 12 is attached to the outer surface of the housing main body 8. At this time, a plurality of waterproof packing 25 are attached in advance in the insertion hole 12a of the lock member 12, and the waterproof member 18 is attached to the outer periphery of the convex portion 17 of the lock member 12. In this state, the convex portion 17 is inserted into the concave portion 8b of the pedestal portion 8a provided on the outer periphery of the case body 8, and the waterproof member 18 is sandwiched between the outer peripheral surface of the convex portion 17 and the inner peripheral surface of the concave portion 8 b.

In this state, the fixing portion 14 of the lock member 12 is fixed to the base portion 8a of the case body 8. At this time, the screw insertion holes 14a provided on both side portions of the fixing portion 14 are made to correspond to the respective screw holes 8c of the base portion 8a, and in this state, the plurality of screw members 16 are screwed and fastened to the respective screw holes 8c of the base portion 8a through the respective screw insertion holes 14a of the fixing portion 14. Thereby, the fixing portion 14 is fixed to the pedestal portion 8a of the case body 8, and the lock member 12 is attached to the outer surface of the case body 8.

In this case, when the fixing portion 14 is fastened and fixed to the pedestal portion 8a by the plurality of screw members 16, the waterproof member 18 interposed between the outer peripheral surface of the convex portion 17 and the inner peripheral surface of the concave portion 8b abuts against the inner surface of the fixing portion 14, whereby the lock member 12 is positioned on the pedestal portion 8a of the housing main body 8. That is, when the fixing portion 14 is fixed to the pedestal portion 8a by the plurality of screw members 16, the attachment state of the fixing portion 14 to the pedestal portion 8a, that is, the inclination of the fixing portion 14 in the vertical and horizontal directions is adjusted by the elastic force of the waterproof member 18.

Thereby, the lock member 12 is positioned with respect to the pedestal portion 8a, and the through hole 11 of the housing main body 8 and the insertion hole 12a of the lock member 12 correspond and coincide on the same axis. At this time, since the waterproof member 18 is interposed between the outer peripheral surface of the convex portion 17 of the fixing portion 14 and the inner peripheral surface of the concave portion 8b of the pedestal portion 8a, the waterproof between the convex portion 17 of the fixing portion 14 and the concave portion 8b of the pedestal portion 8a can be achieved by the waterproof member 18.

In this state, the watch glass 5 is attached to the upper opening of the case body 8, the first exterior portion 9a is attached to the outer periphery of the case body 8, and the second exterior portion 9b is attached to the upper outer periphery of the case body 8 and the upper outer periphery of the first exterior portion 9 a. At this time, both side portions of the fixing portion 14 of the locking member 12 and the plurality of screw members 16 are covered with the exterior member 9 except for the locking portion 15 of the locking member 12.

Then, the operation member 13 is inserted into the insertion hole 12a of the lock member 12 and the through hole 11 of the housing main body 8. At this time, the operation member 13 is assembled in advance. In this case, the cushioning material 27 is inserted into the annular recess 21a of the head 21, and the coil spring 26 is inserted into the non-circular hole 22a and the circular hole 22b in the main body shaft 22.

In this state, the slide coupling portion 23 to which the one end portion of the operation shaft 24 is attached is inserted into the noncircular hole portion 22a of the main body shaft 22 against the elastic force of the coil spring 26, and the stopper portion 22c is attached to the inner end portion in the main body shaft 22. Thereby, the operation shaft 24 is attached to the main shaft 22 via the slide coupling portion 23, and the operation member 13 is assembled.

Then, when the operation member 13 is inserted into the insertion hole 12a of the lock member 12 and the through hole 11 of the case body 8, the timepiece module 7 is previously incorporated into the case body 8. In this state, the operation shaft 24 of the operation member 13 is inserted into the insertion hole 12a of the lock member 12 and the through hole 11 of the case body 8, and is inserted into the timepiece module 7 to be restricted, and the body shaft 22 is inserted into the insertion hole 12a of the lock member 12. As a result, the operating shaft 24 is restrained within the timepiece module 7, and the switch device 4 is assembled because the operating member 13 is completely attached.

In this case, the operating shaft 24 is formed in a rod shape having an outer diameter smaller than the outer diameter of the sliding coupling portion 23 slidably disposed in the main shaft 22, that is, the inner diameter of the small-diameter hole 11a of the through hole 11 of the housing main body 8. Therefore, the small diameter hole 11a of the through hole 11 of the housing main body 8 can be formed to have a small inner diameter with a minimum size into which the operation shaft 24 can be inserted, and the length (thickness) of the housing main body 8 in the vertical direction can be formed to be short (thin).

Next, a case where the switching device 4 is operated will be described.

When the switch device 4 is not used, in the normal state shown in fig. 4, the head 21 of the operating member 13 is pushed toward the inside of the housing body 8 against the elastic force of the coil spring 26, and the head 21 is locked to the locking portion 15 of the locking member 12.

That is, in the normal state shown in fig. 4, the operation shaft 24 of the shaft portion 20 is restricted within the timepiece module 7. In this state, if the head 21 is pushed toward the inside of the housing main body 8, the main body shaft 22 slides toward the inside of the housing main body 8 within the insertion hole 12a of the lock member 12 against the elastic force of the coil spring 26.

At this time, the operation shaft 24, which is stopped in the timepiece module 7, pushes the slide coupling portion 23 into the noncircular hole 22a of the main body shaft 22 as the main body shaft 22 slides, and the stopper portion 23a of the slide coupling portion 23 is separated from the coming-off preventing portion 22c of the main body shaft 22. In this state, the head 21 is rotated in one direction, and the female screw portion 21b of the head 21 is screwed and fastened to the male screw portion 15a of the lock member 12.

Then, the main body shaft 22 is gradually slid toward the inside of the housing main body 8 in the insertion hole 12a of the lock member 12 against the elastic force of the coil spring 26, and the slide coupling portion 23 is gradually pushed into the noncircular hole portion 22a in the main body shaft 22 with the sliding of the main body shaft 22, and the stopper portion 23a is gradually separated from the coming-off prevention portion 22 c.

When the head 21 is rotated in one direction in this way, the stopper 23a of the sliding coupling portion 23 rotates together with the main body shaft 22 in accordance with the rotation of the head 21, the operating shaft 24 rotates in accordance with the rotation of the sliding coupling portion 23, the female screw portion 21b of the head 21 is screwed with the male screw portion 15a of the lock member 12, and the head 21 is locked by the lock portion 15. Therefore, the switching device 4 does not operate accidentally.

When the switch device 4 is operated, first, the head 21 of the operating member 13 is rotated in a direction opposite to the one direction, and the lock of the operating member 13 by the lock member 12 is released. That is, when the head 21 is rotated in the opposite direction, the threaded engagement of the female screw portion 21b of the head 21 with respect to the male screw portion 15a of the lock member 12 is released, and the lock of the head 21 by the lock portion 15 is released.

At this time, the female screw portion 21b of the head 21 is disengaged from the male screw portion 15a of the lock member 12, the main body shaft 22 is pushed out toward the outside of the housing main body 8 together with the head 21 by the spring force of the coil spring 26, the slide coupling portion 23 is pulled out from the noncircular hole portion 22a of the main body shaft 22, and the stopper portion 23a abuts against the stopper portion 22 c.

In this state, if the head 21 is further pulled out of the housing main body 8, the main body shaft 22 slides in the insertion hole 12a of the lock member 12 and is pulled out together with the head 21. At this time, since the sliding coupling portion 23 abuts on the stopper portion 22c, the sliding coupling portion 23 is pulled out together with the main shaft 22. Operating shaft 24 is then pulled out, so operating shaft 24 slides within timepiece module 7. Thereby, the timepiece module 7 is in a state in which the time can be corrected.

In this state, if the head 21 is rotated, the body shaft 22 rotates in the insertion hole 12a of the lock member 12 in accordance with the rotation of the head 21, and the stopper 23a of the slide coupling portion 23 rotates together with the slide coupling portion 23 in accordance with the rotation of the body shaft 22. Then, the operation shaft 24 rotates in the timepiece module 7 in accordance with the rotation of the sliding coupling portion 23. This makes it possible to correct the time of the timepiece module 7.

As described above, the switch device 4 of the wristwatch includes: a case body 8 provided with a through hole 11; a lock member 12 fixed to an outer surface of the housing main body 8 and having an insertion hole 12a at a center thereof coaxially corresponding to the through hole 11; and an operation member 13 slidably inserted into the through hole 11 of the housing body 8 and the insertion hole 12a of the lock member 12 and locked by the lock member 12, whereby the housing body 8 can be thinned even if a lock mechanism for locking the operation member 13 by the lock member 12 is provided.

Further, since the lock member 12 is fixed to the outer surface of the case body 8, the operation member can be locked to the tube in comparison with the conventional structure in which the tube is fitted into the through hole of the case body and fixed in the case body, and the radial direction of the case body 8 and the entire wristwatch can be downsized.

That is, in the switch device 4 of the wristwatch, since the through hole 11 of the case main body 8 can be formed to be small in the minimum size into which the operation member 13 can be inserted, even if a lock mechanism for locking the operation member 13 by the lock member 12 is provided, the thickness of the case main body 8 in the vertical direction can be formed to be thin, and thus the thickness of the case main body 8 can be reduced, and the thickness of the entire wristwatch can be reduced.

Further, by forming the through hole 11 of the case main body 8 to be small in the minimum size into which the operation member 13 can be inserted, the thickness of the case main body around the through hole 11 can be sufficiently ensured, and the strength of the case main body 8 can be improved. The inner diameters of the small-diameter hole 11a and the large-diameter hole 11b of the through hole 11 may be the same.

In this case, in the switch device 4, since the external thread portion 15a is provided on the outer peripheral surface of the locking portion 15 of the lock member 12 and the internal thread portion 21b is provided on the inner peripheral surface of the recess 21a provided in the head portion 21 of the operating member 13, the lock mechanism can be configured, and therefore, the internal thread portion 21b of the head portion 21 can be screwed and fastened to the external thread portion 15a of the locking portion 15 in a state where the operating member 13 is pushed toward the inside of the housing body 8, and the operating member 13 can be reliably and satisfactorily locked to the housing body 8.

In the switch device 4, since the locking member 12 includes the fixing portion 14 fixed to the outer surface of the housing body 8 and the locking portion 15 for lockably unlocking the operating member 13, the fixing portion 14 can be fixed to the outer surface of the housing body 8 in a state where the insertion hole 12a of the locking member 12 and the through hole 11 of the housing body 8 are coaxially aligned, and therefore, even if the locking member 12 includes the locking portion 15 for locking the operating member 13, the locking member 12 can be reliably and satisfactorily attached to the outer surface of the housing body 8 through the fixing portion 14.

In this case, the fixing portion 14 is provided with screw insertion holes 14a at both side portions, and when the fixing portion is disposed on the pedestal portion 8a provided on the outer surface of the case main body 8, the screw insertion holes 14a and the screw holes 8c provided on the pedestal portion 8a are respectively made to correspond to each other, and in this state, the plurality of screw members 16 are screwed and fastened to the screw holes 8c of the pedestal portion 8a through the screw insertion holes 14a, whereby the fixing portion can be reliably and firmly fixed to the pedestal portion 8a of the case main body 8. Further, since the fixing portion 14 and the locking portion 15 of the locking member 12 are formed integrally, the number of parts can be reduced, and the assembly work can be simplified.

In the switch device 4, the operating member 13 includes the shaft portion 20 slidably inserted into the through hole 11 of the housing body 8 and the insertion hole 12a of the lock member 12, and the head portion 21 provided at the outer end of the shaft portion 20 and locked to the lock member 12 so as to be unlocked, so that the shaft portion 20 can be slid well in the through hole 11 of the housing body 8 and the insertion hole 12a of the lock member 12 by sliding the head portion 21, and the shaft portion 20 can be rotated well in the through hole 11 of the housing body 8 and the insertion hole 12a of the lock member 12 by rotating the head portion 21.

In this case, even if the outer diameter of the head portion 21 is larger than the outer diameter of the shaft portion 20, the outer diameter of the shaft portion 20 inserted into the through hole 11 of the housing main body 8 can be made smaller than the outer diameter of the head portion 21, and therefore the inner diameter of the through hole 11 of the housing main body 8 can be formed small in the minimum size into which the shaft portion 20 can be inserted, and thus the thickness of the housing main body 8 in the vertical direction can be formed thin.

That is, in the switch device 4, the shaft portion 20 includes: a main body shaft 22 slidably inserted into the insertion hole 12a of the lock member 12; and an operation shaft 24 having a smaller diameter than the main shaft 22, attached to the main shaft 22 via the slide coupling portion 23, and slidably inserted into the housing main body 8 through the through hole 11 of the housing main body 8, so that the operation shaft 24 can be prevented from being pressed into the housing main body 8 excessively by the slide coupling portion 23 when the operation member 13 is pressed toward the inside of the housing main body 8 rather than locked to the lock member 12.

In this case, since the shaft portion 20 is formed such that the main shaft 22 is slidably inserted into the insertion hole 12a of the lock member 12 and is not inserted into the through hole 11 of the housing main body 8, and the operation shaft 24 is slidably inserted into the through hole 11 of the housing main body 8, and the outer diameter of the operation shaft 24 is formed smaller than the outer diameter of the main shaft 22, even if the outer diameter of the main shaft 22 is larger than the outer diameter of the operation shaft 24, the inner diameter of the through hole 11 of the housing main body 8 can be formed small in the minimum size into which the small-diameter operation shaft 24 can be inserted, and thus the thickness of the housing main body 8 in the vertical direction can be reliably formed thin.

Further, in the switch device 4, the waterproof member 18 is provided, and the waterproof member 18 is disposed between the inner peripheral surface of the concave portion 8b of the base portion 8a provided on the outer surface of the housing main body 8 and the outer peripheral surface of the convex portion 17 provided on the inner end surface of the fixing portion 14 of the lock member 12 and inserted into the concave portion 8b of the base portion 8a, whereby the waterproof between the convex portion 17 of the fixing portion 14 and the concave portion 8b of the base portion 8a can be achieved by the waterproof member 18.

In the switch device 4, the waterproof member 18 positions the lock member 12 with respect to the pedestal portion 8a on the outer surface of the housing main body 8, so that when the fixing portion 14 is fixed to the pedestal portion 8a by the plurality of screw members 16, the inclination of the fixing portion 14 in the vertical and horizontal directions, which is the state of attachment of the fixing portion 14 to the pedestal portion 8a, can be adjusted by the elastic force of the waterproof member 18. Accordingly, the lock member 12 can be accurately and satisfactorily positioned with respect to the pedestal portion 8a, and therefore the through hole 11 of the housing main body 8 and the insertion hole 12a of the lock member 12 can be aligned coaxially.

(second embodiment)

Next, a second embodiment of a wristwatch to which the present invention is applied will be described with reference to fig. 5 to 8. Note that the same components as those of the first embodiment shown in fig. 1 to 4 are denoted by the same reference numerals.

As shown in fig. 5 to 8, the locking portion 30 of the locking member 12 of the wristwatch has a structure different from that of the first embodiment, but is substantially the same as that of the first embodiment.

That is, as shown in fig. 5 to 7, the locking portion 30 is a cylindrical portion provided on the outer surface of the fixing portion 14, and is structured such that an engaging portion 31 is provided on the outer peripheral surface in a state of being separated from the outer surface of the fixing portion 14. The locking portion 31 is configured to lock the head portion 21 of the operation member 13 so as to be capable of locking and releasing, and has a structure in which convex portions 31a and concave portions 31b are alternately provided in the circumferential direction.

On the other hand, as shown in fig. 5, 6, and 8, the head portion 21 of the operating member 13 is provided with an engaging portion 32 that is detachably engaged with the engaging portion 31 of the lock portion 30. The engaging portion 32 is provided at an end portion of the inner peripheral surface of the head portion 21 on the side of the lock member 12 in the recess 21 a. That is, the engaging portion 32 has a structure in which convex portions 32a and concave portions 32b are alternately provided in the circumferential direction, similarly to the locking portion 31 of the lock portion 30. The locking portion 31 of the lock portion 30 and the engaging portion 32 in the head portion 21 constitute a lock mechanism.

Thus, as shown in fig. 5 to 8, when the head portion 21 of the operating member 13 is pushed toward the inside of the housing body 8 against the elastic force of the coil spring 26 and the engaging portion 32 of the head portion 21 faces the engaging portion 31 of the lock portion 30, if the head portion 21 is rotated so that the concave portion 31b of the engaging portion 31 and the convex portion 32a of the engaging portion 32 correspond to each other, the convex portion 32a of the engaging portion 32 passes through the concave portion 31b of the engaging portion 31.

As shown in fig. 5 to 8, the lock portion 30 is configured such that, when the head portion 21 is rotated and the convex portion 31a of the engaging portion 31 and the convex portion 32a of the engaging portion 32 are correspondingly overlapped with each other in a state where the engaging portion 32 of the head portion 21 passes through the locking portion 31 of the lock portion 30, the opposing surface of the convex portion 32a of the engaging portion 32 facing the inner surface of the convex portion 31a of the engaging portion 31 is abutted against the inner surface of the convex portion 31a of the engaging portion 31 by the elastic force of the coil spring 26, thereby locking the head portion 21.

As shown in fig. 5 to 8, the locking portion 30 is configured such that, in a state where the head portion 21 is locked, if the head portion 21 is rotated and the concave portion 31b of the locking portion 31 and the convex portion 32a of the engaging portion 32 are brought into correspondence with each other, the locking of the head portion 21 is released. That is, when the head portion 21 is unlocked, the locking portion 30 is configured such that the head portion 21 is pushed out to the outside of the housing body 8 by the elastic force of the coil spring 26, the convex portion 32a of the engaging portion 32 passes through the concave portion 31b of the locking portion 31, and the head portion 21 is pushed out to the outside of the housing body 8.

According to the switch device 4 of the wristwatch, in addition to the same operational effects as those of the first embodiment, since the locking portion 31 is provided in the locking portion 30 of the locking member 12 and the engaging portion 32 is provided in the recess 21a of the head portion 21, the head portion 21 can be locked simply and reliably only by rotating the head portion 21 by a predetermined angle in a pushed-in state.

That is, in the switch device 4, when the head portion 21 of the operating member 13 is pushed toward the inside of the case body 8, the head portion 21 is rotated by a predetermined angle, and the concave portion 31b of the engaging portion 31 and the convex portion 32a of the engaging portion 32 are brought into correspondence, the concave portion 32b of the engaging portion 32 passes through the concave portion 31b of the engaging portion 31, and the head portion 21 is rotated in this state, and the convex portion 31a of the engaging portion 31 and the convex portion 32a of the engaging portion 32 are brought into correspondence and overlap with each other, whereby the head portion 21 can be easily locked.

In the switch device 4, when the head portion 21 is locked and the concave portion 31b of the locking portion 31 and the convex portion 32a of the engaging portion 32 are brought into correspondence with each other by rotating the head portion 21, the convex portion 32a of the engaging portion 32 passes through the concave portion 31b of the locking portion 31, and therefore the locking of the head portion 21 can be easily released, and the locking operation by the locking portion 30 can be simplified.

In the first and second embodiments described above, the fixing portion 14 of the lock member 12 is attached to the outer surface of the housing main body 8 by the plurality of screw members 16, but the present invention is not limited to this, and for example, the fixing portion 14 integrally formed with the lock portion 15 of the lock member 12 may be integrally formed with the housing main body 8 by insert molding. In such a configuration, since the pedestal portion 8a does not need to be provided on the outer surface of the case main body 8 as in the first and second embodiments described above, the outer diameter of the case main body 8 can be made small, and the wristwatch can be downsized.

In the first and second embodiments described above, the fixing portion 14 of the locking member 12 and the locking portions 15 and 30 are integrally formed, but the present invention is not limited to this, and the fixing portion 14 and the locking portions 15 and 30 may be formed of different members, and the locking portions 15 and 30 may be fixed to the outer surface of the housing main body 8 via the fixing portion 14.

In such a configuration, the fixing portion 14 and the locking portions 15, 30 are formed of different members, and therefore, the impact received from the outside by the operating member 13 can be dispersed. The locking portions 15 and 30 and the waterproof member 18 can prevent the housing body 8 from being broken, and the screw member 16 that fixes the fixing portion 14 to the outer surface of the housing body 8 can be prevented from being broken.

In the first and second embodiments described above, the switch device 4 provided on the 3 o ' clock side of the wristwatch case 1 has been described, but the present invention is not limited to this, and can be applied to the push switches 3 on the 2 o ' clock side, the 4 o ' clock side, the 8 o ' clock side, and the 10 o ' clock side of the wristwatch case 1.

Further, although the first and second embodiments and the modifications thereof have been described with respect to the case of being applied to a wristwatch, the present invention is not necessarily required to be applied to a wristwatch, and can be applied to various timepieces such as a travel wristwatch, an alarm clock, a desk clock, and a wall clock. Additionally, the utility model discloses need not necessarily to be clock and watch, also can be applied to electronic equipment such as cell-phone, mobile terminal.

The present invention is not limited to the above embodiments, but includes the embodiments described in the claims and their equivalents.
