[0016] Hereinafter, various embodiments of the present invention will be described with reference to the drawings. It should be noted that the technical scope of the present invention is not limited to these embodiments, but covers the invention described in the claims and their equivalents.
[0017] 1 and 2 are perspective views of a wallet watch 1 according to a first embodiment of the present invention. The wallet watch 1 comprises a watch 11, a support member 12, a crown 13, a hanging ring 14, a fixed shaft 15, and the like.
[0018] Timepiece 11 is an analog timepiece and includes exterior case 111 and crystal 112. Exterior case 111 houses a movement, dial, and hands (not shown). Crystal 112 is placed on the front of exterior case 111 (the side on which the hour characters and hands on the dial are visible) so as to cover the dial and hands built into exterior case 111. Timepiece 11 indicates the time by the hands driven by the movement pointing to the hour characters on the dial.
[0019] The support member 12 is configured to support the crown 13 and the strap ring 14, and is disposed on the side of the exterior case 111. For example, the support member 12 is disposed in the 12 o'clock direction of the timepiece 11.
[0020] Crown 13 is a component for receiving rotational operation for the movement. Crown 13 is connected to the movement by penetrating the side of support member 12 and exterior case 111. When the user rotates crown 13, the rotational force is transmitted to the movement and the time is adjusted.
[0021] The hanging ring 14 is a component for attaching a chain or a string. The hanging ring 14 is curved, and at both ends thereof, through holes 141 are formed into which the fixed shaft 15 connected to the support member 12 is inserted. The fixed shaft 15 is inserted into the through hole 141, and the hanging ring 14 is rotatably held by the support member 12.
[0022] As shown in Figures 1 and 2, the hanging ring 14 can rotate around the fixed shaft 15 relative to the support member 12 in response to the user's operation. On the other hand, due to the frictional force generated between the hanging ring 14 and the support member 12 and the fixed shaft 15, the hanging ring 14 does not rotate due to gravity applied thereto or the inertial force applied thereto when the watch 11 is carried. Therefore, the hanging ring 14 can remain stationary in an inclined state, for example, as shown in Figure 2. In other words, the hanging watch 1 makes it possible to prevent the hanging ring 14 from rotating unnecessarily.
[0023] The support member 12, the crown 13, the hanging ring 14, the fixed shaft 15, etc. will be described in detail below.
[0024] Fig. 3 is a cross-sectional view of the vicinity of the hanging ring 14 of the wallet watch 1 along the III-III cross section in Fig. 1, and Fig. 4 is an exploded perspective view of the fixed shaft 15. The wallet watch 1 further has a holding member 16, a regulating member 17, and the like.
[0025] The support member 12 has a crown support part 121 that supports the crown 13, and a first hanging ring support part 122a and a second hanging ring support part 122b that respectively support both ends of the hanging ring 14. The crown support part 121 is formed with an insertion hole 123 through which the crown 13 is inserted, facing the watch 11. The first hanging ring support part 122a and the second hanging ring support part 122b are formed with a first insertion hole 124a and a second insertion hole 124b, respectively, through which the fixed shaft 15 is inserted. Hereinafter, the first insertion hole 124a and the second insertion hole 124b may be simply referred to as the insertion hole 124 when there is no need to distinguish between them.
[0026] The crown 13 has an operating unit 131, an axis unit 132, and a winding stem 133. The operating unit 131 is disposed on the first support unit 121 of the support member 12 so that the user can perform a rotation operation. The axis unit 132 is a cylindrical member inserted into the insertion hole 123 of the support member 12. The winding stem 133 is a shaft-shaped member that fits into the hollow part of the axis unit 132 and is connected to the movement. In the example shown in FIG. 3, the operating unit 131 and the axis unit 132 are integrally formed, and the axis unit 132 rotates in conjunction with the rotation of the operating unit 131. The winding stem 133 also rotates in conjunction with the rotation of the axis unit 132 with which it fits. In this way, the rotational force is transmitted from the operating unit 131 to the movement. It should be noted that the crown 13 is not limited to the above-mentioned example, and may have any configuration that can transmit a rotational force to the movement in response to a rotational operation.
[0027] The hanging ring 14 is curved in a substantially U-shape, and a first through hole 141a and a second through hole 141b are formed at both ends thereof. The first through hole 141a is formed to face the first insertion hole 124a, and the second through hole 141b is formed to face the second insertion hole 124b. That is, the first through hole 141a and the first insertion hole 124a are arranged to face each other in the axial direction of the fixed shaft 15. The second through hole 141b and the second insertion hole 124b are arranged to face each other in the axial direction of the fixed shaft 15. Preferably, the first through hole 141a, the second through hole 141b, the first insertion hole 124a, and the second insertion hole 124b are formed to be coaxial. This allows the hanging ring 14 to rotate smoothly. Hereinafter, the first through hole 141a and the second through hole 141b may be simply referred to as the through hole 141 when there is no need to distinguish between them.
[0028] The fixed shaft 15 is a shaft-like member for fixing the hanging ring 14 to the support member 12. As shown in FIG. 4, the fixed shaft 15 has a shaft portion 151, a head portion 152, a first groove portion 153, a second groove portion 154, and a third groove portion 155. The shaft portion 151 has a generally cylindrical shape with a diameter generally the same as that of the through hole 141 of the hanging ring 14 and the insertion hole 124 of the support member 12. The head portion 152 is disposed at one end of the shaft portion 151, and has a cylindrical shape with a diameter larger than that of the shaft portion 151. The first groove portion 153, the second groove portion 154, and the third groove portion 155 are formed along the circumferential direction of the shaft portion 151 over the entire circumference thereof.
[0029] The pair of fixed shafts 15 are connected to the support member 12 by inserting the shaft portions 151 into the insertion holes 124 of the support member 12. The shaft portions 151 of the pair of fixed shafts 15 are inserted into the through holes 141 of the hanging ring 14, so that the hanging ring 14 is rotatably supported with respect to the support member 12. As shown in FIG. 3, when the fixed shafts 15 are inserted into the through holes 141 and the insertion holes 124, the first groove portion 153 is located inside the through hole 141, the second groove portion 154 is located inside the insertion hole 124, and the third groove portion 155 is formed so as to be exposed from the insertion hole 124.
[0030] The holding member 16 includes a first holding member 161 and a second holding member 162 formed as separate bodies. The first holding member 161 and the second holding member 162 are each formed of an elastic material such as NBR (Nitril-Butadiene Rubber). The first holding member 161 holds the first groove portion 153 of the fixed shaft 15 in the circumferential direction. The second holding member 162 holds the second groove portion 154 of the fixed shaft 15 in the circumferential direction. In the example shown in FIG. 4, the first holding member 161 and the second holding member 162 are O-rings that are annular members having a circular cross-sectional shape. In this case, the first holding member 161 and the second holding member 162 hold the first groove portion 153 and the second groove portion 154, respectively, over the entire circumference along the circumferential direction.
[0031] The radial width of the first holding member 161 and the second holding member 162 is greater than the depth of the first groove portion 153 and the second groove portion 154, respectively. Therefore, when the fixed shaft 15 is inserted into the through hole 141 of the hanging ring 14 and the insertion hole 124 of the support member 12, the first holding member 161 contacts the bottom surface of the first groove portion 153 and the inner peripheral surface S1 of the through hole 141, and presses these surfaces with elastic force. Similarly, the second holding member 162 contacts the bottom surface of the second groove portion 154 and the inner peripheral surface S2 of the insertion hole 124, and presses these surfaces with elastic force. As a result, a large static friction force is generated between the fixed shaft 15 and the hanging ring 14 and the support member 12. At this time, a lubricant such as silicone grease may be applied to the surface of the first holding member 161 or the second holding member 162 so that the static friction force is not too large and the rotation of the hanging ring 14 is not hindered.
[0032] The restricting member 17 is a member for restricting the axial movement of the fixed shaft 15 inserted into the through hole 141 and the insertion hole 124. In the example shown in Fig. 3 and Fig. 4, the restricting member 17 is a washer. The restricting member 17 has an outer diameter larger than the insertion hole 124 of the support member 12, and holds the third groove portion 155 of the fixed shaft 15 that penetrates the insertion hole 124, thereby restricting the axial movement of the fixed shaft 15.
[0033] When inserting the fixed shaft 15 into the through hole 141 and the insertion hole 124, first, the first holding member 161 and the second holding member 162 are attached to the first groove portion 153 and the second groove portion 154 of the fixed shaft 15. With the first holding member 161 and the second holding member 162 attached, the fixed shaft 15 is inserted into the through hole 141 and the insertion hole 124.
[0034] At this time, the outer edge E1 of the through hole 141 on the outside (meaning the direction opposite to the support member 12 side) is formed in a tapered shape inclined with respect to the axial direction of the fixed shaft 15. Therefore, when the first holding member 161 and the second holding member 162 contact the tapered surface of the outer edge E1 of the through hole 141, the force for inserting the fixed shaft 15 into the through hole 141 is converted into a force for compressing the first holding member 161 and the second holding member 162 in the radial direction. As a result, the fixed shaft 15 to which the first holding member 161 and the second holding member 162 are attached can be easily inserted into the through hole 141.
[0035] Similarly, the outer edge E2 of the insertion hole 124 on the outer side (the side of the hanging ring 14) is also formed in a tapered shape inclined with respect to the axial direction of the fixed shaft 15. Therefore, when the second holding member 162 comes into contact with the tapered surface of the outer edge E2 of the insertion hole 124, the force for inserting the fixed shaft 15 into the insertion hole 124 is converted into a force that radially compresses the second holding member 162. This allows the fixed shaft 15 to which the second holding member 162 is attached to be easily inserted into the insertion hole 124.
[0036] Thereafter, the restricting member 17 is attached to the third groove portion 155 of the fixed shaft 15 that passes through the insertion hole 124, and the movement of the fixed shaft 15 in the axial direction is restricted.
[0037] As described above, the fob clock 1 has the hanging ring 14 with the through holes 141 formed at both ends, the support member 12 with a pair of insertion holes 124 formed to face the through holes 141 and supporting the hanging ring 14, the fixed shaft 15 inserted into the through hole 141 and the insertion hole 124 to rotatably hold the hanging ring 14 on the support member 12, and the holding member 16 formed of an elastic material and holding the fixed shaft 15 in the circumferential direction. When the fixed shaft 15 is inserted into the through hole 141 and the insertion hole 124, the holding member 16 comes into contact with the bottom surface of the groove of the fixed shaft 15, the inner peripheral surface S1 of the through hole 141, and the inner peripheral surface S2 of the insertion hole 124. This allows the fob clock 1 to generate large static frictional forces between the support member 12 and the hanging ring 14, and the fixed shaft 15, respectively, and to prevent the hanging ring 14 from rotating unnecessarily.
[0038] Moreover, the holding member 16 includes a first holding member 161 and a second holding member 162, each of which is formed as a separate body. When the fixed shaft 15 is inserted into the through hole 141 and the insertion hole 124, the first holding member 161 comes into contact with the outer circumferential surface of the fixed shaft 15 and the inner circumferential surface S1 of the through hole 141. In this state, the second holding member 162 comes into contact with the outer circumferential surface of the fixed shaft 15 and the inner circumferential surface S2 of the insertion hole 124. This allows the wristwatch 1 to generate large static friction forces between the support member 12 and the fixed shaft 15, and between the hanging ring 14 and the fixed shaft 15, respectively, and makes it possible to prevent the hanging ring 14 from rotating unnecessarily.
[0039] Furthermore, the fixed shaft 15 has a first groove portion 153 and a second groove portion 154 formed along the circumferential direction, and the first holding member 161 and the second holding member 162 respectively hold the first groove portion 153 and the second groove portion 154. By forming the grooves in the fixed shaft 15, the difference between the outer diameter of the shaft portion 151 and the outer diameter of the holding member 16 attached to the fixed shaft 15 becomes smaller, and the fixed shaft 15 can be easily inserted into the through hole 141 and the insertion hole 124 when assembling the wallet watch 1.
[0040] In addition, the first holding member 161 and the second holding member 162 are annular members. This increases the contact area between the first holding member 161 and the second holding member 162 and the inner circumferential surfaces of the through hole 141 and the insertion hole 124, and generates a large circumferential static friction force between the support member 12 and the hanging ring 14 and the fixed shaft 15. This makes it possible to more reliably prevent the hanging ring 14 from rotating unnecessarily.
[0041] In addition, the pair of through holes 141 and the pair of insertion holes 124 are coaxial with each other. This prevents rattling caused by rotation of the hanging ring 14, and prevents wear on the hanging ring 14 and the fixed shaft 15.
[0042] Furthermore, the outer edges E1 and E2 of the through hole 141 and the insertion hole 124 are formed in a tapered shape that is inclined with respect to the axial direction of the fixed shaft 15. This makes it possible to easily insert the fixed shaft 15 into the through hole 141 and the insertion hole 124 when assembling the wallet watch 1.
[0043] The wallet clock 1 may have the following modified examples.
[0044] In the above-mentioned embodiment, the first holding member 161 and the second holding member 162 are O-rings, which are annular members having a circular cross-sectional shape. The present invention is not limited to such an example, and may be annular members having other cross-sectional shapes, such as trapezoidal rings and X-rings. In this case, too, a large circumferential static friction force is generated between the support member 12 and the hanging ring 14 and the fixed shaft 15. However, it is preferable that the holding member 16 is an O-ring, trapezoidal ring, or the like, whose surface that contacts the outer edges E1 and E2 of the through hole 141 and the insertion hole 124 when the fixed shaft 15 is inserted is inclined toward the head 152 so that the fixed shaft 15 can be easily inserted into the through hole 141 and the insertion hole 124 when the wristwatch 1 is assembled.
[0045] In addition, the first holding member 161 and the second holding member 162 are not limited to annular members. For example, the first holding member 161 and the second holding member 162 may be members formed to have a C-shape as a whole and arranged to hold only a part of the groove in the circumferential direction. This makes it possible to easily attach the first holding member 161 and the second holding member 162 to the fixed shaft 15. In this case, the first holding member 161 and the second holding member 162 may be members in which the surface of a material with relatively low elasticity, such as resin, is covered with an elastic material, such as NBR. When the first holding member 161 and the second holding member 162 hold only a part of the groove in the circumferential direction, there is a possibility that the first holding member 161 and the second holding member 162 will deform in the circumferential direction as the hanging ring 14 rotates. By incorporating a material with relatively low elasticity into the first holding member 161 and the second holding member 162, the deformation in the circumferential direction of the first holding member 161 and the second holding member 162 is prevented as much as possible.
[0046] In the above-described embodiment, the fob clock 1 has a retaining member 16 for each of the pair of fixed shafts 15. However, the present invention is not limited to this example, and the fob clock 1 may have a retaining member 16 for only one fixed shaft 15. For example, the retaining member 16 may be attached to the fixed shaft 15 inserted into the through hole 141 formed at one end of the fob ring 14, and the retaining member 16 may not be attached to the fixed shaft inserted into the through hole 141 formed at the other end. Even in this way, the fob ring 14 can be prevented from rotating unnecessarily due to the frictional force generated by the retaining member 16 attached to one fixed shaft 15.
[0047] In the above embodiment, the restricting member 17 is a washer, but is not limited to this example, and the restricting member 17 may be an annular member such as an O-ring.
[0048] In the above-described embodiment, the outer edges E1 and E2 of the through hole 141 and the insertion hole 124 are formed in a tapered shape. However, the present invention is not limited to this example, and the outer edges E1 and E2 may be formed so that the inner circumferential surfaces of the through hole 141 and the insertion hole 124 are connected at right angles to the surfaces of the hanging ring 14 and the support member 12. Even in this case, since the holding member 16 is made of an elastic material, the fixed shaft 15 can be inserted into the through hole 141 and the insertion hole 124 with the holding member 16 attached.
[0049] 5 is a cross-sectional view of the vicinity of the hanging ring of the bag watch according to the second embodiment. The bag watch according to the second embodiment differs from the bag watch 1 according to the first embodiment in that it has a fixed shaft 25 and a holding member 26 instead of the fixed shaft 15 and the holding member 16. Other configurations of the bag watch according to the second embodiment are similar to the corresponding configurations of the bag watch 1, so the same reference numerals are used and the description will be omitted.
[0050] Fixed shaft 25 differs from fixed shaft 15 in that it has a fourth groove portion 256 instead of first groove portion 153 and second groove portion 154. Fourth groove portion 256 is formed over the entire circumference of fixed shaft 25 along the circumferential direction of shaft portion 151. Moreover, fourth groove portion 256 is formed so that a portion of it is located inside through hole 141 and another portion is located inside insertion hole 124 when fixed shaft 25 is inserted into through hole 141 and insertion hole 124.
[0051] The holding member 26 is integrally formed from an elastic material and holds the fourth groove portion 256 of the fixed shaft 25 in the circumferential direction. The holding member 26 has a predetermined width in the axial direction so as to come into contact with the bottom surface of the fourth groove portion 256, the inner circumferential surface S1 of the through hole 141, and the inner circumferential surface S2 of the insertion hole 124 when the fixed shaft 25 is inserted into the through hole 141 of the hanging ring 14 and the insertion hole 124 of the support member 12. As a result, the holding member 26 presses these surfaces with its elastic force.
[0052] In this way, the hanging watch according to the second embodiment has a retaining member 26 which is formed as a single unit and which, when the fixed shaft 25 is inserted into the through hole 141 of the hanging ring 14 and the insertion hole 124 of the support member 12, comes into contact with the bottom surface of the fourth groove portion 256, the inner peripheral surface S1 of the through hole 141, and the inner peripheral surface S2 of the insertion hole 124. Even in this way, large static frictional forces are generated between the support member 12 and the hanging ring 14 and the fixed shaft 25, respectively, and it is possible to prevent the hanging ring 14 from rotating unnecessarily.
[0053] In the above-described embodiment, the holding member 26 is formed as a single unit. However, the present invention is not limited to this example. The holding member 26 may include a first holding member that is formed as a separate unit and that contacts the bottom surface of the fourth groove portion 256 and the inner circumferential surface S1 of the through hole 141 when the fixed shaft 25 is inserted into the through hole 141 of the hanging ring 14 and the insertion hole 124 of the support member 12, and a second holding member that contacts the bottom surface of the fourth groove portion 256 and the inner circumferential surface S2 of the insertion hole 124. Even in this manner, a large static friction force is generated between the support member 12 and the hanging ring 14 and the fixed shaft 25, respectively, and the hanging ring 14 can be prevented from rotating unnecessarily.
[0054] 6 is a cross-sectional view of the vicinity of the hanging ring of the bag watch according to the third embodiment. The bag watch according to the third embodiment differs from the bag watch 1 according to the first embodiment in that it has a fixed shaft 35 instead of the fixed shaft 15, and in that it does not have a second holding member 162. The other configurations of the bag watch according to the third embodiment are similar to the corresponding configurations of the bag watch 1, so the same reference numerals are used and the description will be omitted.
[0055] The fixed shaft 35 differs from the fixed shaft 15 in that it has an engagement portion 357 instead of the second groove portion 154. The engagement portion 357 is a configuration for engaging the fixed shaft 35 with the support member 12, and is formed on the shaft portion 151 of the fixed shaft 35. In the example shown in FIG. 6, the engagement portion 357 is a screw thread that screws together the fixed shaft 35 with the support member 12. The static friction force in the circumferential direction generated between the fixed shaft 35 and the support member 12 is greater than the static friction force in the circumferential direction generated between the fixed shaft 35 and the first holding member 161 so that the fixed shaft 35 does not rotate relative to the support member 12 as the hanging ring 14 rotates.
[0056] In this way, the hanging watch according to the third embodiment has a first holding member 161 that contacts the fixed shaft 35 and the inner circumferential surface S1 of the through hole 141 when the fixed shaft 35 is inserted into the through hole 141 and the insertion hole 124, but does not have a second holding member 162 that contacts the fixed shaft 35 and the inner circumferential surface S2 of the insertion hole 124. Even in this way, a large static friction force can be generated between the hanging ring 14 and the fixed shaft 35, preventing the hanging ring 14 from rotating unnecessarily.
[0057] In the above-described embodiment, the engagement portion 357 is configured to screw the fixed shaft 35 and the support member 12 together. However, the present invention is not limited to this example, and the engagement portion 357 may engage the fixed shaft 35 and the support member 12 in any manner that prevents the fixed shaft 35 from rotating relative to the support member 12 as the hanging ring 14 rotates. Furthermore, the fixed shaft 35 may not have the engagement portion 357, and may be fixed to the support member 12 by adhesion, press fitting, or the like.
[0058] 7 is a cross-sectional view of the vicinity of the hanging ring of the bag watch according to the fourth embodiment. The bag watch according to the fourth embodiment differs from the bag watch 1 according to the first embodiment in that it has a fixed shaft 45 instead of the fixed shaft 15, and in that it does not have a first holding member 161. The other configurations of the bag watch according to the fourth embodiment are similar to the corresponding configurations of the bag watch 1, so the same reference numerals are used and the description will be omitted.
[0059] The fixed shaft 45 differs from the fixed shaft 15 in that it has an engagement portion 457 instead of the first groove portion 153. The engagement portion 457 is a configuration for engaging the fixed shaft 45 with the hanging ring 14, and is formed on the shaft portion 151 of the fixed shaft 45. In the example shown in FIG. 7, the engagement portion 457 is a thread that screws the fixed shaft 45 with the hanging ring 14. In order to prevent the hanging ring 14 from rotating relative to the fixed shaft 45 as the hanging ring 14 rotates, the static friction force in the circumferential direction generated between the fixed shaft 45 and the hanging ring 14 is greater than the static friction force in the circumferential direction generated between the fixed shaft 45 and the second holding member 162. This allows the hanging ring 14 and the fixed shaft 45 to rotate integrally around the central axis of the fixed shaft 45 when the hanging ring 14 is rotated. In other words, the hanging ring 14 and the fixed shaft 45 can be rotated integrally relative to the second holding member 162.
[0060] In this way, the wallet watch according to the fourth embodiment has the second holding member 162 that contacts the fixed shaft 45 and the inner circumferential surface S2 of the insertion hole 124 when the fixed shaft 45 is inserted into the through hole 141 and the insertion hole 124, but does not have the first holding member 161 that contacts the fixed shaft 45 and the inner circumferential surface S1 of the through hole 141. Even in this way, a large static friction force can be generated between the support member 12 and the fixed shaft 45, preventing the hanging ring 14 from rotating unnecessarily.
[0061] In the above-described embodiment, the engagement portion 457 is configured to screw the fixed shaft 45 and the hanging ring 14 together. However, the present invention is not limited to this example, and the engagement portion 457 may engage the fixed shaft 45 and the hanging ring 14 in any manner that does not cause the support member 12 to rotate in association with the rotation of the hanging ring 14. Furthermore, the fixed shaft 45 may not have the engagement portion 457, and may be fixed to the hanging ring 14 by adhesion, press fitting, or the like.
[0062] 8 is a cross-sectional view of the vicinity of the hanging ring of the bag watch according to the fifth embodiment. The bag watch according to the fifth embodiment differs from the bag watch 1 in that it has a support member 52, a hanging ring 54 and a fixed shaft 55 instead of the support member 12, the hanging ring 14 and the fixed shaft 15. The other configurations of the bag watch according to the fifth embodiment are similar to the corresponding configurations of the bag watch 1, so the same reference numerals are used and the description will be omitted.
[0063] Fixed shaft 55 differs from fixed shaft 15 in that it does not have first groove portion 153 and second groove portion 154. Hanging ring 54 differs from hanging ring 14 in that a groove portion 542 is formed along the circumferential direction on the inner circumferential surface of through hole 141. Support member 52 differs from support member 12 in that a groove portion 525 is formed along the circumferential direction on the inner circumferential surface of insertion hole 124. First holding member 161 is housed in groove portion 542, and second holding member 162 is housed in groove portion 525.
[0064] The radial width of the first holding member 161 and the second holding member 162 is larger than the depth of the groove 542 and the groove 525. The inner diameter of the first holding member 161 and the second holding member 162 is smaller than the outer diameter of the shaft portion 151 of the fixed shaft 55. Therefore, when the fixed shaft 55 is inserted into the through hole 141 and the insertion hole 124, the first holding member 161 contacts the outer circumferential surface of the shaft portion 151 of the fixed shaft 55 and the bottom surface S3 of the groove portion 542, and presses these surfaces by elastic force. Similarly, the second holding member 162 contacts the outer circumferential surface of the shaft portion 151 of the fixed shaft 55 and the bottom surface S4 of the groove portion 525, and presses these surfaces by elastic force.
[0065] In this way, the wristwatch according to the fifth embodiment has a first holding member 161 that contacts the outer circumferential surface of the shaft portion 151 and the bottom surface S3 of the groove portion 542 with the fixed shaft 55 inserted into the through hole 141 and the insertion hole 124, and a second holding member 162 that contacts the outer circumferential surface of the shaft portion 151 and the bottom surface S4 of the groove portion 525. Even in this way, large static frictional forces are generated between the support member 12 and the hanging ring 14, and between the fixed shaft 55 and the hanging ring 14, respectively, making it possible to prevent the hanging ring 14 from rotating unnecessarily.
[0066] 9 is a cross-sectional view of the vicinity of the hanging ring of the bag watch according to the sixth embodiment. The bag watch according to the sixth embodiment differs from the bag watch 1 according to the first embodiment in that it has a support member 62 and a fixed shaft 65 instead of the support member 12 and the fixed shaft 15, and in that it does not have the second holding member 162 and the regulating member 17. The other configurations of the bag watch according to the sixth embodiment are similar to the corresponding configurations of the bag watch 1, so the same reference numerals are used and the description will be omitted.
[0067] The fixed shaft 65 has a shaft portion 651, a head portion 652, and a first groove portion 653. In addition, the second support portion 122 of the support member 62 does not have an insertion hole 124. Instead of being inserted into the insertion hole 124, the shaft portion 651 is connected to the support member 62 by being integrally formed with the second support portion 122 of the support member 62. The head portion 652 has an outer diameter larger than that of the shaft portion 651, and is screwed into a portion of the shaft portion 651 exposed from the through hole 141. The first holding member 161 holds the first groove portion 653 of the shaft portion 651 in the circumferential direction, and contacts the bottom surface of the first groove portion 653 and the inner circumferential surface S1 of the through hole 141 when the shaft portion 651 is inserted into the through hole 141.
[0068] In this way, the wallet watch according to the sixth embodiment has a fixed shaft 65 having an axle 651 formed integrally with the support member 62, and a first holding member 161 that contacts the axle 651 and the inner circumferential surface S1 of the through hole 141 when the axle 651 is inserted into the through hole 141. Even in this way, a large static frictional force can be generated between the hanging ring 14 and the axle 651 of the fixed shaft 65, preventing the hanging ring 14 from rotating unnecessarily.
[0069] In the above-described embodiment, the shaft portion 651 is formed integrally with the support member 62. However, the present invention is not limited to this example, and the shaft portion 651 may be formed separately from the support member 62 and connected to the support member 62 by being adhered to the support member 62.
[0070] 9, the first groove 653 is formed in the shaft portion 651 of the fixed shaft 65, but is not limited thereto. For example, a groove extending in the circumferential direction of the inner circumferential surface S1 may be formed in the inner circumferential surface S1 of the through hole 141 of the hanging ring 14, and the first holding member 161 may be disposed in the groove. In other words, the first holding member 161 may be disposed between the outer circumferential surface of the shaft portion 651 and the bottom surface of the groove.
[0071] It should be understood by those skilled in the art that various changes, substitutions, and modifications can be made to the present invention without departing from the scope of the present invention. For example, the above-mentioned embodiments and modifications may be appropriately combined within the scope of the present invention. [Explanation of symbols]
