When the watch case 1 is attached to the wrist, even if the watch band 8 is pulled with respect to the watch case 1, the pair of reinforcing members 12 are firmly fixed to the case main body 2 by the retaining portions 15, so that The wristwatch case 1 can be satisfactorily attached to the arm by the watch band 8 without the reinforcing member 12 coming out of the case body 2 and being detached.

  Further, since the watch band 8 is attached to the band attaching portion 10 by the fastening member 16, even if the watch band 8 is formed of a soft synthetic resin such as urethane resin, the fastening member 16 The one end portion 8a is securely and satisfactorily attached to the band attaching portion 10. For this reason, even if the watch band 8 is pulled with respect to the watch case 1, the end portion 8 a of the watch band 8 is not detached from the band attaching portion 10, and the watch case 1 is attached to the arm satisfactorily by the watch band 8. be able to.

  That is, the fastening member 16 includes the first screw member 17 and the female screw portion 18b of the second screw member 18 in a state where the first screw member 17 and the second screw member 18 are inserted into the cylindrical member 19. The male screw portion 17a is screwed and tightened. As a result, the pair of reinforcing members 12 are pressed against both end portions of the tubular member 19, so that the one end portion 8 a of the watch band 8 is securely and firmly attached to the band attaching portion 10.

  On the other hand, when the watch band 8 thus attached to the band attaching portion 10 is attached to the arm, the one end portion 8a of the watch band 8 rotates around the tubular member 19 of the fastening member 16, and the watch band 8 Fits your arm. At this time, one end portion 8a of the watch band 8 rotates around the fastening member 16, but the rotation restricting member 20 is restrained by the rotation preventing member 22 so that the rotation of the rotation restricting member 20 is prevented. The rotation range of the one end 8 a of the watch band 8 is regulated by the rotation regulating member 20.

  That is, when the one end portion 8 a of the watch band 8 rotates about the fastening member 16 toward the upper side of the band attaching portion 10, the upper surface of the one end portion 8 a of the watch band 8 is connected to the connecting side portion 20 b of the rotation regulating member 20. Since the sides abut, the rotation of the one end 8a of the watch band 8 is restricted. Further, when the one end portion 8 a of the watch band 8 rotates around the fastening member 16 toward the lower side of the band attaching portion 10, the lower surface of the one end portion 8 a of the watch band 8 is the thick portion 11 of the band attaching portion 10. Therefore, the rotation of the one end 8a of the watch band 8 is restricted.

  As a result, the one end portion 8a of the watch band 8 has a position where the lower surface of the one end portion 8a of the watch band 8 abuts on the thick portion 11 of the band attaching portion 10 and the upper surface of the one end portion 8a of the watch band 8 is a rotation restricting member. The rotation range of the one end portion 8a of the timepiece band 8 is restricted by rotating between the position that contacts the 20 connecting side portions 20b. Thereby, the watch band 8 can be attached in a state in which the watch band 8 is well fitted to the arm.

  When the wristwatch case 1 is removed from the arm, the one end portion 8a of the watch band 8 can be rotated around the fastening member 16 to remove the watch band 8 from the arm. Also at this time, when the one end portion 8a of the watch band 8 rotates about the fastening member 16 toward the upper side of the band attaching portion 10, the one end portion 8a of the watch band 8 is connected to the connecting side portion 20b of the rotation restricting member 20. Since the upper surface side of the abutment comes into contact, the rotation of the one end portion 8a of the watch band 8 is restricted. Thereby, since the one end part 8a of the watch band 8 does not rotate more than necessary, the watch case 1 can be removed from the arm well.

  In this state, when the wristwatch case 1 is placed on the table facing upward, the rotation of the one end portion 8a of the watch band 8 around the fastening member 16 is restricted by the connecting side portion 20b of the rotation restricting member 20. Thus, the wristwatch case 1 is elastically arranged in a state where it floats on the table by the one end 8a of the watch band 8.

  Thus, according to the wristband mounting structure of this wristwatch, the wristwatch case 1 provided with the band mounting portion 10, the watch band 8 in which the one end 8 a is disposed between the band mounting portions 10, and the watch band 8 A rotation restricting member 20 which is disposed on both sides of the one end portion 8a and suppresses the rotation of the watch band 8 relative to the watch case 1 and the one end portion 8a of the watch band 8 is rotated together with the rotation restricting member 20 to the band attaching portion 10. The rotation of the timepiece band 8 is ensured by including the fastening member 16 that can be attached, and the anti-rotation member 22 that restricts the rotation of the timepiece band 8 and the rotation restriction member 20 around the fastening member 16. And can be well regulated.

  That is, in this wristband mounting structure of the wristwatch, when the watchband 8 rotates around the fastening member 16, the rotation restricting member 20 suppresses the rotation of the watchband 8 relative to the band mounting portion 10 of the watchcase 1 and rotates the watchband 8. The rotation range of the watch band 8 can be reliably regulated by the stop member 22. For this reason, even if the watch band 8 is formed of a soft synthetic resin, the rotation of the watch band 8 can be reliably and well regulated.

  In this case, the rotation preventing member 22 is configured to restrict the rotation of the watch band 8 by suppressing the rotation of the rotation restricting member 20 around the fastening member 16, so that the rotation of the watch case 1 with respect to the band attaching portion 10 is restricted. The rotation of the member 20 can be inhibited and prevented by the rotation preventing member 22. Thus, when the watch band 8 rotates around the fastening member 16, the rotation regulating member 20 whose rotation is prevented by the rotation preventing member 22. Thus, even when the watch band 8 is formed of a soft synthetic resin, the rotation range of the watch band 8 can be reliably regulated.

  That is, the rotation restricting member 20 connects the pair of side portions 20 a disposed on both sides of the one end portion 8 a of the watch band 8 and the pair of side portions 20 a across the upper surface side of the one end portion 8 a of the watch band 8. The connecting side portion 20b, and the fastening portion 16 in a state where the thin attachment portion 21 of the pair of side portions 20a is disposed between the one end portion 8a of the watch band 8 and the band attachment portion 10. By being rotatably attached to the band attaching portion 10, when the one end portion 8 a of the watch band 8 rotates around the fastening member 16, the rotation restricting member 20 can reduce the rotation range of the one end portion 8 a of the watch band 8. It can be reliably and well regulated.

  That is, the rotation restricting member 20 includes a position where the lower surface of the one end portion 8a of the watch band 8 contacts the thick portion 11 of the band attaching portion 10 when the watch band 8 rotates around the fastening member 16. The rotation range of the one end portion 8a of the watch band 8 is rotated by rotating the one end portion 8a of the watch band 8 between the position where the upper surface of the one end portion 8a of the band 8 contacts the connecting side portion 20b of the rotation restricting member 20. Can be reliably and well regulated.

  Further, in this band mounting structure, the rotation preventing member 22 is provided with the pin mounting hole 23 provided in the band mounting portion 10 and the pin regulating hole provided in the rotation regulating member 20 and corresponding to the pin mounting hole 23 on the same axis. 24 and the pin attachment hole 23 and the pin member 25 inserted into the pin restriction hole 24, the pin member 25 is changed from the pin attachment hole 23 of the band attachment portion 10 to the pin restriction hole 24 of the rotation restriction member 20. With a simple structure that only needs to be inserted, the position of the rotation restricting member 20 can be reliably restricted with respect to the band attaching portion 10, and thus the rotation restricting member 20 can be reliably prevented from rotating with respect to the band attaching portion 10. it can.

  In this case, even if the attachment cover portion 13 of the band attachment portion 10 is formed of a soft synthetic resin such as urethane resin, the reinforcing member 12 of the band attachment portion 10 is formed of a metal such as stainless steel, and the rotation restricting member 20. Is formed of a highly rigid synthetic resin such as a polyamide-based resin, the position of the rotation restricting member 20 with respect to the band attaching portion 10 can be surely restricted by the pin member 25, thereby the band attaching portion 10. The rotation restricting member 20 can be reliably prevented from rotating.

  Further, in this band mounting structure, the fastening member 16 is a female screw in which the first screw member 17 having the male screw portion 17a, the neck portion 17b, and the head portion 17c and the male screw portion 17a of the first screw member 17 are screwed together. A second screw member 18 having a shaft portion 18a provided with a portion 18b, a neck portion 18c, and a head portion 18d, whereby the one end portion 8a of the watch band 8 is attached to the band by the fastening member 16. It can be securely attached to the portion 10.

  In this case, the fastening member 16 is inserted into the through hole 8b provided in the one end portion 8a of the watch band 8 and is disposed between the pair of reinforcing members 12, and the first screw member 17 and the second screw member. By further including a cylindrical member 19 into which the first screw member 17 is inserted, the first screw member 17 and the second screw member 18 are inserted into the cylindrical member 19 and the male screw portion of the first screw member 17 is inserted. The one end portion 8a of the watch band 8 can be firmly attached to the band attaching portion 10 by screwing the 17a into the female screw portion 18b of the second screw member 18 and tightening.

  That is, when the fastening member 16 is tightened by screwing the male screw portion 17a of the first screw member 17 into the female screw portion 18b of the second screw member 18, the head portion 17c of the first screw member 17 is attached to one side. Since the cover portion 13 is pressed against the one reinforcing member 12 and the head portion 18d of the second screw member 18 presses the other mounting cover portion 13 against the other reinforcing member 12, the pair of reinforcing members 12 are connected to the cylindrical member 19. The one end portion 8a of the watch band 8 can be firmly attached between the pair of reinforcing members 12 of the band attaching portion 10, and the rotation restricting member 20 is attached to the cylindrical member 19. Can be attached securely.

  Further, in this band mounting structure, each pin mounting hole 23 of the rotation stop member 22 of the band mounting portion 10 is provided with the head portion 17c of the first screw member 17 and the head portion 18d of the second screw member 18 of the fastening member 16. Are provided in the corresponding regions E, that is, in the counterbore portions 13b of the attachment cover portions 13 of the band attachment portion 10, respectively, so that each pin member 25 is connected to the head portion 17c of the first screw member 17 and the first portion. Each of the two screw members 18 can be covered with a head portion 18d.

  That is, each pin member 25 of the rotation stopper member 22 is inserted into each pin attachment hole 23 of the band attachment portion 10 and each pin restriction hole 24 of the rotation restriction member 20, and the rotation restriction member 20 with respect to the band attachment portion 10. Since each pin member 25 can be covered with the head portion 17c of the first screw member 17 and the head portion 18d of the second screw member 18 while preventing the rotation of the pin member 25, the pin member 25 is prevented from falling off. And each pin member 25 can be hidden so that it cannot be seen from the outside, and this can provide what is preferable in terms of appearance and design.

(Second Embodiment)
Next, a second embodiment in which the present invention is applied to a wristwatch will be described with reference to FIG. In addition, the same code | symbol is attached | subjected and demonstrated to the same part as 1st Embodiment shown by FIGS.
As shown in FIG. 7, this wristwatch has a configuration different from the first embodiment in the pin regulation hole 30 of the rotation stop member 22 provided in the mounting portion 21 of the rotation regulation member 20, and the other configuration is the first embodiment. It has the same configuration as

  That is, as shown in FIG. 7, the pin restricting hole 30 of the rotation preventing member 22 is formed from the outer diameter of the pin member 25 along an arc centering on the insertion hole 21a into which the cylindrical member 19 of the fastening member 16 is inserted. Is also formed long. In this case, the pin restricting hole 30 may be formed so that the length in the arc direction around the insertion hole 21a is within about twice the diameter of the pin member 25, and preferably 1 of the diameter of the pin member 25. It is about 5 times longer. Thereby, the pin restricting hole 30 is configured such that the pin member 25 inserted therein moves by a predetermined angle range along an arc centered on the inserting hole 21a.

  In such a wristwatch band mounting structure, the same effects as those of the first embodiment are obtained, and the pin restricting hole 30 of the rotation preventing member 22 is arranged outside the pin member 25 along an arc centered on the insertion hole 21a. By being formed longer than the diameter, when the one end 8 a of the watch band 8 rotates around the fastening member 16, the pin member 25 of the rotation stopping member 22 is predetermined along the pin restricting hole 30. It can be moved by an angular range.

  For this reason, since the rotation restricting member 20 can be rotated around the fastening member 16 only within a range in which the pin member 25 relatively moves within the pin restricting hole 30 of the rotation stopping member 22, the fastening member 16 is the center. The rotation range of the one end portion 8a of the watch band 8 can be expanded, thereby improving the wearability of the watch band 8 with respect to the arm, and the watch band 8 can be further improved compared to the first embodiment. Can fit well.

Is also formed long. Thereby, the pin restricting hole 30 is configured so that the pin member 25 inserted therein moves by a predetermined angle range along an arc centered on the inserting hole 21a.

  As shown in FIG. 8, a first elastic deformation portion 31 and a second elastic deformation portion 32 are provided at both ends in the longitudinal direction of the pin restricting hole 30. The first elastically deforming portion 31 approaches the end portion 30a of the pin restricting hole 30 positioned in the clockwise direction in FIG. 8 with the insertion hole 21a provided in the attachment portion 21 of the rotation restricting member 20 as the center. By providing the hole portion 31a, a thin wall portion is formed between the first hole portion 31a and the end portion 30a of the pin restricting hole 30 approaching the first hole portion 31a.

  In this case, as shown in FIG. 8, the first hole portion 31 a of the first elastically deforming portion 31 has an inner peripheral surface at a location approaching the end portion 30 a of the pin restricting hole 30, and the end portion 30 a of the pin restricting hole 30. Is formed so as to project substantially in parallel with the arc of the first hole 31a toward the inside of the first hole 31a, and the inner peripheral surface of the portion facing this is substantially parallel with the arc of the end 30a of the pin restricting hole 30. Is formed.

  As a result, as shown in FIG. 8, the first elastic deformation portion 31 pushes the pin member 25 inserted into the pin restricting hole 30 in the clockwise direction in FIG. 8 to the end portion 30 a of the pin restricting hole 30. When applied, the thin portion located between the end 30a of the pin restricting hole 30 and the first hole 31a is configured to be elastically deformed toward the first hole 31a.

  On the other hand, the second elastic deformation portion 32 is, as shown in FIG. 8, the pin restriction hole 30 located in the counterclockwise direction in FIG. 8 centering on the insertion hole 21 a provided in the attachment portion 21 of the rotation restriction member 20. By providing the second hole portion 32a close to the end portion 30b, the thin hole is formed between the second hole portion 32a and the end portion 30b of the pin regulating hole 30 approaching the second hole portion 32a, as in the first elastically deformable portion 31. It is formed as a part.

  Also in this case, as shown in FIG. 8, the second hole portion 32 a of the second elastically deformable portion 32 has an inner peripheral surface at a location approaching the end portion 30 b of the pin restricting hole 30 at the end of the pin restricting hole 30. It is formed so as to protrude into the second hole portion 32a substantially in parallel with the same arc as the arc of the portion 30b, and the inner peripheral surface of the portion facing this is the same arc as the arc of the end portion 30b of the pin regulating hole 30 They are formed almost in parallel.

  As a result, as shown in FIG. 8, the second elastic deformation portion 32 moves the pin member 25 inserted into the pin restricting hole 30 in the counterclockwise direction in FIG. 8 to the end 30 b of the pin restricting hole 30.

Since the first elastic deformation portion 31 and the second elastic deformation portion 32 are provided on both sides, the one end portion 8a of the watch band 8 rotates around the fastening member 16, and the pin member 25 of the rotation stop member 22 When moving by a predetermined angle range along the pin restricting hole 30, either one of the first elastic deformation portion 31 and the second elastic deformation portion 32 can be elastically deformed to buffer the impact. .

  That is, in this band mounting structure, the pin member 25 of the rotation stop member 22 extends along the pin restricting hole 30 when the one end portion 8a of the watch band 8 rotates toward the upper side of the watch case 1 around the fastening member 16. The pin member 25 moved relatively in a predetermined angle range and moved relatively in the pin restricting hole 30 is pressed against the end portion 30a of the pin restricting hole 30, whereby the end of the pin restricting hole 30 is Since the first elastic deformation portion 31 located in the portion 30a is elastically deformed toward the first hole portion 31a, the impact can be buffered by the elastic deformation of the first elastic deformation portion 31.

  Similarly, in this band mounting structure, when the one end 8 a of the watch band 8 is rotated toward the lower side of the watch case 1 around the fastening member 16, the pin member 25 of the rotation stop member 22 enters the pin restricting hole 30. The pin member 25 moved relatively along a predetermined angle range along the pin restricting hole 30 and pressed relative to the pin restricting hole 30 is pressed against the end 30b of the pin restricting hole 30, thereby Since the second elastic deformation portion 32 located at the end 30b is elastically deformed toward the second hole portion 32a, the impact can be buffered by the elastic deformation of the second elastic deformation portion 32.

  In the above-described third embodiment, the case where the pin restricting hole 30 of the rotation preventing member 22 is formed longer than the outer diameter of the pin member 25 is described. As in the first embodiment, the inner diameter may be the same as the outer diameter of the pin member 25. Also in this case, if the first elastic deformation portion 31 and the second elastic deformation portion 32 are provided at both ends of the pin restricting hole located in the direction along the circular arc centering on the insertion hole 21a into which the fastening member 16 is inserted. good.

  Further, in each of the first to third embodiments described above, the case where the rotation stopping members 22 are provided on both sides of the band attaching portion 10 of the wristwatch case 1 and on both sides of the rotation restricting member 20 has been described. Instead, the rotation stopper member 22 may be provided only on one side of the band attaching portion 10 of the wristwatch case 1 and on one side of the rotation restricting member 20 corresponding thereto.
