In this case, the coil spring 13 has a pedestal portion even if the upper side of the pedestal portion 17 protrudes above the storage hole portion 20 when the regulation protrusion portion 16 is pushed out toward the upper side of the storage hole portion 20 by the spring force thereof. The spring force is set so that the lower side of 17 is maintained in a state of being arranged in the large-diameter hole portion 20a of the storage hole portion 20.

By the way, as shown in FIGS. 3 and 5, the regulation protrusion 16 of the rotation regulation member 12 is formed in a chevron shape so as to be inserted into the engagement recess 15 of the rotation bezel 11 so as to be retractable. That is, the regulating protrusion 16 is brought into contact with and separated from the slide portion 16a that is pushed down in response to the slide of the first inclined portion 15a in the engaging recess 15 of the rotating bezel 11 and the second inclined portion 15b of the engaging recess 15. It is provided with a contact portion 16b and a contact portion 16b that can abut with each other.

In this case, as shown in FIG. 3A, the pedestal portion 17 is formed on the upper surface of the pedestal portion 17 and the lower surface of the rotating bezel 11 when the regulating protrusion 16 is inserted into the engaging recess 15 of the rotating bezel 11. On a plane substantially the same as the bottom surface of the notch 9 of the wristwatch case 1 which is arranged under the rotating bezel 11 with a slight gap between the pedestals 17 and whose upper surface of the pedestal 17 is located at the upper end of the storage hole 20. It is configured to be placed in.

Further, as shown in FIG. 3B, the regulating protrusion 16 is inserted into the engaging recess 15 of the rotating bezel 11 when the rotating bezel 11 is rotated in one direction (arrow X direction). By sliding the first inclined portion 15a of the engaging recess 15 in contact with the sliding portion 16a, the sliding portion 16a is configured to be gradually pushed down against the spring force of the coil spring 13.

Further, as shown in FIG. 3B, the regulating protrusion 16 has a contact portion 16b of the engaging recess 15 when the slide portion 16a is gradually pushed down against the spring force of the coil spring 13.

There is.

In this case, as shown in FIG. 3B, the coil spring 13 is compressed by the pedestal portion 17 when the upper end portion 16c of the regulation protrusion portion 16 gets over the second inclined portion 15b of the engaging recess portion 15. As a result, the rotational force of the rotating bezel 11 is increased, and when the regulating protrusion 16 is inserted into the adjacent engaging recess 15, the compressed coil spring 13 is extended to sharply reduce the rotational force of the rotating bezel 11. , The rotating bezel 11 is configured to give a click feeling.

Further, as shown in FIG. 3A, the restricting protrusion 16 rotates the rotating bezel 11 in a direction opposite to one direction (arrow X direction) while being inserted into the engaging recess 15 of the rotating bezel 11. The contact portion 16b is maintained in contact with the second inclined portion 15b of the engaging recess 15 so as to prevent the rotating bezel 11 from rotating in the opposite direction.

Next, the operation of the rotating device 10 of such a wristwatch will be described.
When assembling the rotating device 10, first, the rotation restricting member 12 is placed in the coil spring 13 in the storage hole 20 provided on the 9 o'clock side at the bottom of the notch 9 located on the upper outer periphery of the wristwatch case 1. Place with. At this time, the guide shaft 18 provided on the lower surface of the pedestal portion 17 of the rotation restricting member 12 is inserted into the coil spring 13, and the coil spring 13 is arranged on the outer periphery of the guide shaft 18.

In this state, the coil spring 13 and the guide shaft 18 are inserted into the storage hole 20 of the notch 9 of the wristwatch case 1 from above and arranged in the small diameter hole 20b of the storage hole 20. In this state, as shown in FIG. 6, the lower end of the coil spring 13 is in contact with the bottom of the storage hole 20, and the upper end of the coil spring 13 is in contact with the lower surface of the pedestal 17. Grow to the natural state.

In this state, the upper side of the pedestal portion 17 projects upward from the storage hole portion 20 together with the regulation protrusion portion 16, and the lower side of the pedestal portion 17 is arranged in the large-diameter hole portion 20a of the storage hole portion 20. Therefore, even if the regulation protrusion 16 projects above the storage hole 20, the rotation restricting member 12 has the storage hole 20 because the lower side of the pedestal 17 is arranged in the storage hole 20. It is placed in a stable state inside.

In this state, the rotating bezel 11 is attached to the notch 9 of the wristwatch case 1. At this time, the packing 14 is mounted in advance in the mounting recess 11a provided on the inner peripheral surface of the rotating bezel 11. Then, the rotating bezel 11 is fitted into the notch 9 of the wristwatch case 1 from above, and the engaging portion 11b of the rotating bezel 11 is engaged with the locking projection 9a of the notch 9 of the wristwatch case 1.

As a result, the rotating bezel 11 is rotatably attached to the notch 9 of the wristwatch case 1 without slipping out above the wristwatch case 1. At this time, the regulation protrusion 16 of the rotation regulation member 12 is pushed down by the lower surface of the rotation bezel 11. Therefore, the coil spring 13 is slightly compressed, and the upper side of the pedestal portion 17 is pushed into the large-diameter hole portion 20a of the storage hole portion 20.

In this case, when the regulating protrusion 16 of the rotation regulating member 12 is inserted into the engaging recess 15 provided on the lower surface of the rotating bezel 11, the sliding portion 16a of the regulating protrusion 16 becomes the first engaging recess 15. 1 Facing the inclined portion 15a in a parallel state with a gap, the contact portion 16b of the regulating protrusion 16 abuts on the second inclined portion 15b of the engaging recess 15, and the upper end portion 16c of the regulating protrusion 16 is the engaging recess. It abuts on the bottom 15c of 15.

At this time, the height of the regulating protrusion 16, that is, the length of the regulating protrusion 16 protruding from the pedestal 17 toward the rotating bezel 11 is approximately the same as or greater than the depth of the engaging recess 15 of the rotating bezel 11. Is also formed a little longer. Therefore, when the regulation protrusion 16 is inserted into the engagement recess 15 and the upper end 16c of the regulation protrusion 16 comes into contact with the bottom 15c of the engagement recess 15, the pedestal 17 is formed in the notch 9 of the wristwatch case 1. It is pushed into the storage hole 20.

At this time, the pedestal portion 17 of the rotation restricting member 12 is arranged below the rotating bezel 11 with a slight gap between the upper surface thereof and the lower surface of the rotating bezel 11, and the upper surface of the pedestal portion 17 is a storage hole portion. It is arranged on substantially the same plane as the bottom surface of the notch 9 of the wristwatch case 1 located at the upper end of the 20. As a result, the pedestal portion 17 of the rotation restricting member 12 is arranged so as not to come into contact with the lower surface of the rotating bezel 11.

Next, the operation of the rotating device 10 will be described.
When the rotating bezel 11 is rotated in one direction (arrow X direction) with the restricting protrusion 16 of the rotation restricting member 12 inserted into the engaging recess 15 provided on the lower surface of the rotating bezel 11, the rotating bezel 11 is rotated. As the rotation of 11, the engaging recess 15 of the rotating bezel 11 moves in the rotation direction (arrow X direction).

At this time, the first inclined portion 15a of the engaging recess 15 slides in contact with the slide portion 16a of the regulating protrusion 16, and the slide portion 16a slides in response to the slide of the first inclined portion 15a to spring the coil spring 13. It is gradually pushed down against the force. Therefore, the contact portion 16b of the regulation protrusion 16 is gradually pushed down along the second inclined portion 15b of the engaging recess 15, and the upper end portion 16c of the regulation protrusion 16 gets over the second inclined portion 15b and engages. It is pushed out of the joint recess 15. At this time, since the coil spring 13 is compressed by the pedestal portion 17, the rotational force of the rotating bezel 11 becomes heavy.

In this state, when the rotary bezel 11 is further rotated in one direction (arrow X direction), the rotary bezel 11 rotates with the upper end portion 16c of the regulation protrusion 16 in contact with the lower surface of the rotary bezel 11. When the adjacent engaging recess 15 corresponds to the regulating protrusion 16 with the rotation of the rotating bezel 11, the regulating protrusion 16 is inserted into the adjacent engaging recess 15.

At this time, the upper end portion 16c of the regulation protrusion portion 16 is gradually pushed up along the first inclined portion 15a of the engagement recess 15 by the spring force of the compressed coil spring 13. As a result, the slide portion 16a of the regulation protrusion 16 faces the first inclined portion 15a of the engagement recess 15, and the contact portion 16b of the regulation protrusion 16 comes into contact with the second inclined portion 15b of the engagement recess 15. The upper end 16c of the regulation protrusion 16 comes into contact with the bottom 15c of the engaging recess 15.

In this way, when the regulation protrusion 16 is inserted into the adjacent engaging recess 15, the compressed coil spring 13 is stretched by its elastic recovery force, so that the rotational force of the rotating bezel 11 is sharply reduced. As a result, a click feeling is given to the rotating bezel 11.

Further, in this way, when the rotating bezel 11 is rotated in the direction opposite to one direction (arrow X direction) with the regulating protrusion 16 inserted in the engaging recess 15, the contact portion of the regulating protrusion 16 is formed. Since the second inclined portion 15b of the engaging recess 15 is in contact with the 16b, the reverse rotation of the rotating bezel 11 is prevented. Therefore, the rotating bezel 11 rotates in only one direction (arrow X direction).

Further, since the rotation restricting member 12 does not rotate about the guide shaft 18 in the storage hole portion 20, the second inclined portion 15b of the engaging recess 15 abuts on the abutting portion 16b of the regulating protrusion portion 16. This prevents the rotating bezel 11 from rotating in the reverse direction.

As described above, according to the rotating device 10 of the wristwatch, the rotating device 10 is rotatably arranged on the outer periphery of the wristwatch case 1 which is the main body of the device, and the engaging recesses 15 are provided on the lower surface at equal intervals along the circumference. It is arranged on the bezel 11 and the wristwatch case 1 located below the rotating bezel 11, and can be engaged with or disengaged from any of the engaging recesses 15 according to the rotation of the rotating bezel 11 in one direction (arrow X direction). By providing a rotation regulating member 12 that engages and regulates the rotation position of the rotating bezel 11 and a coil spring 13 that urges the rotation regulating member 12 toward the rotating bezel 11, the rotation with a click feeling is provided. The bezel 11 can be rotated in one direction, and the entire device can be miniaturized.

That is, in the rotating device 10 of this wristwatch, the rotation restricting member 12 can be engaged with the engaging recess 15 of the rotating bezel 11 in a disengageable manner in response to the rotation of the rotating bezel 11 in one direction (direction of arrow X). Therefore, the rotating bezel 11 can be rotated in one direction with a click feeling, and the entire device is not restricted in the radial direction, so that the outer diameter of the entire device does not increase and the size of the entire device is small. Can be achieved.

In this case, in the rotating device 10, the rotation restricting member 12 can appear and disappear toward the rotating bezel 11 at a predetermined position of the wristwatch case 1 located below the rotating bezel 11, that is, at one location located on the 9 o'clock side. By providing the storage hole portion 20 to be arranged, the rotation restricting member 12 can be easily and easily attached to the wristwatch case 1, and the storage hole portion 20 can be avoided from a plurality of push button switches 3 and the like. Can be provided. Therefore, the rotating device 10 has a simple structure, can be easily manufactured, and can save space.

Further, in the rotating device 10, the rotation regulating member 12 is provided with a regulating protrusion 16 for inserting the rotation regulating member 12 into the engaging recess 15 of the rotating bezel 11 so as to be able to appear and disappear, and the regulating protrusion 16 is provided, and the outer periphery thereof is an engaging recess. By providing the pedestal portion 17 larger than the inner circumference of 15, the pedestal portion 17 is not inserted into the engaging recess 15, so that only the regulating protrusion 16 is satisfactorily inserted into the engaging recess 15. It can be inserted so that the pedestal portion 17 does not get caught in the engaging recess 15 and the rotating bezel 11 can be smoothly rotated.

Further, in the rotating device 10, the engaging recess 15 of the rotating bezel 11 is located on the side opposite to the rotating direction of the rotating bezel 11 in one direction (arrow X direction), and slides in contact with the rotation restricting member 12. The first inclined portion 15a that pushes down the rotation restricting member 12 while moving, and the second inclined portion 15b that is located in the rotation direction of the rotation bezel 11 in one direction and is in contact with the rotation restricting member 12 so as to be in contact with each other. By providing the rotating bezel 11, the rotating bezel 11 can be satisfactorily rotated in only one direction, and the rotating bezel 11 can be prevented from rotating in the opposite direction.

In this case, the restricting protrusion 16 of the rotation restricting member 12 has a slide portion 16a that is pushed down according to the slide of the first inclined portion 15a in the engaging recess 15 of the rotating bezel 11 and a second inclined portion 15b of the engaging recess 15. The first inclined portion 15a of the engaging recess 15 when the rotating bezel 11 is rotated in one direction (arrow X direction) is provided with the abutting portion 16b that comes into contact with the engaging recess 16b. Since the slide portion 16a is surely pushed down, the rotating bezel 11 can be smoothly rotated in one direction.

Further, when the rotating bezel 11 rotates in one direction (arrow X direction) and the first inclined portion 15a of the engaging recess 15 pushes down the slide portion 16a of the regulating protrusion 16, the regulating protrusion 16 is formed. The contact portion 16b of the 16 is pushed down along the second inclined portion 15b of the engaging recess 15, and the upper end portion 16c of the regulating protrusion 16 gets over the second inclined portion 15b, so that the regulating protrusion 16 engages. Since it is surely and satisfactorily extruded from the recess 15, the rotating bezel 11 can be smoothly and satisfactorily rotated in one direction.

Further, in the regulating protrusion 16, when the rotating bezel 11 is rotated in the direction opposite to one direction (arrow X direction), the second inclined portion 15b of the engaging recess 15 becomes the contact portion 16b of the regulating protrusion 16. Since they come into contact with each other, it is possible to reliably prevent the rotating bezel 11 from rotating in the opposite direction, thereby reliably preventing the rotating bezel 11 from rotating in the reverse direction.

In this case, the regulation protrusion 16 is formed so that its height, that is, the length protruding from the pedestal 17 toward the rotating bezel 11, is the same as or slightly longer than the depth of the engagement recess 15. When the regulation protrusion 16 is inserted into the engagement recess 15, the pedestal 17 can be arranged in a state of being pushed down to the lower side of the rotating bezel 11, whereby the pedestal 17 can be placed in the engagement recess 15. Since the contact can be prevented, the rotating bezel 11 can be rotated smoothly and satisfactorily.

Further, since the upper end portion 16c of the regulation protrusion 16 is formed in an arc shape, when the regulation protrusion 16 is pushed out from the engaging recess 15, the upper end portion 16c inclines the second inclination. The portion 15b can be smoothly passed over, and the lower surface of the rotating bezel 11 can be smoothly slid by the arc-shaped upper end portion 16c, and when the regulation protrusion 16 is inserted into the adjacent engaging recess 15. In addition, the first inclined portion 15a of the engaging recess 15 can be smoothly slid by the arc-shaped upper end portion 16c, and the regulating protrusion 16 can be smoothly inserted into the engaging recess 15.
