  Thus, according to the wristwatch case 1, the main body case 5, the metal outer member 6 disposed on the outer periphery of the upper portion of the main body case 5, and the outer case member 6 are locked. A shock-absorbing mounting member 16 provided on the outer periphery of the outer casing 6 so as to be displaceable in the vertical direction which is perpendicular to the circumferential direction, and a soft synthetic resin attached to the outer periphery of the main body case 5 so as to cover the outer peripheral edge of the exterior member 6 By providing the exterior case 7 made of, the impact resistance can be secured and the entire wristwatch case 1 can be downsized.

  That is, in the wristwatch case 1, when the exterior case 7 receives an impact, the impact can be mitigated by the elasticity of the exterior case 7 made of a soft synthetic resin, and the impact received by the exterior case 7 can be reduced. When transmitted to the exterior member 6, the exterior member 6 is pushed down, and the shock-absorbing attachment member 16 can be displaced with respect to the main body case 5 in the vertical direction, which is a direction orthogonal to the circumferential direction. Thereby, since the impact can be buffered by the elasticity of the exterior case 7 and the displacement of the buffer mounting member 16, the impact resistance can be ensured and the watch case 1 as a whole can be miniaturized.

  In this case, since the exterior member 6 is made of metal, the thickness of the exterior member 6 can be reduced, and the exterior case 7 is formed of a soft synthetic resin. 7, the impact can be mitigated. However, when the exterior case 7 cannot absorb the impact, the shock mounting member 16 can be depressed to displace the impact. For this reason, since the thickness of the exterior case 7 can be reduced, the entire wristwatch case 1 can be reduced in thickness and the size can be reduced.

  Moreover, in this wristwatch case 1, the exterior member 6 has the hook portion 6c, the buffer mounting member 16 engages the hook portion 6c of the exterior member 6, and the lower end portion of the exterior member 6 from above. With the pair of buffer portions 22 disposed so as to be displaceable in the direction perpendicular to the circumferential direction on the outer periphery of the main body case 5 in the abutted state, the buffer mounting member 16 is attached to the pair of buffer portions 16. Since the hook portion 6c of the exterior member 6 can be locked to the locking portion 21 of the buffer mounting member 16 in a state where the buffer portion 22 is arranged on the outer peripheral portion of the main body case 5, the exterior member 6 is attached to the main body case 5. It can be surely and satisfactorily arranged on the upper surface.

  In this case, a screw hole 18 into which the screw member 17 is screwed is provided in the outer peripheral portion of the main body case 5, and the screw member 17 is orthogonal to the circumferential direction of the outer periphery of the main body case 5 in the buffer mounting member 16. Since the guide hole 24 that is inserted so as to be relatively movable in the up-and-down direction, which is the direction in which the shock absorber is mounted, corresponds to the screw hole 18 of the main body case 5, the buffer mounting member 16 is smoothly attached to the main body case 5. And can be displaced well.

  That is, when the exterior case 7 receives an impact from above, the impact is transmitted to the exterior member 6, the exterior member 6 is pushed down, and the buffer mounting member 16 is pushed down by the depressed exterior member 6. Since the screw member 17 screwed into the screw hole 18 can be relatively guided and moved by the guide hole 24 of the buffer mounting member 16, the buffer mounting member 16 can be displaced smoothly and satisfactorily with respect to the main body case 5. In addition, the shock can be reliably and satisfactorily buffered.

  Further, in the wristwatch case 1, a band attaching portion 15 to which the one end portion 2 a of the watch band 2 is attached is provided on the outer periphery of the main body case 5, and the buffer attaching member 16 is provided on the band attaching portion 15.

And it can arrange | position favorably.

  That is, each of the pair of buffer portions 22 of the buffer mounting member 16 is in contact with the slide portion 22a slidably disposed on the outer surface of the pair of mounting protrusions 15a of the band mounting portion 15 and the exterior member 6 from above, Since the upper surface of the pair of mounting projections 15a has a buffer contact portion 22b corresponding to the mounting protrusion 15a, and the guide hole 24 is provided in the slide portion 22a corresponding to the screw hole 18, the slide portion 22a. By screwing the screw member 17 into the screw hole 18 of the mounting protrusion 15a through the slide hole 24, the screw member 17 can be relatively guided and moved along the slide hole 24. Since the buffer mounting member 16 can be displaced smoothly and satisfactorily with respect to the portion 15, the shock can be reliably and satisfactorily buffered.

  In this case, the exterior member 6 is bonded to the upper surface of the main body case 5 by a double-sided adhesive tape 11 having a cushioning property, so that the exterior member 6 is not temporarily rotated with respect to the main body case 5 in the circumferential direction. In addition to being able to be fixed, when the exterior case 7 receives an impact from above, the impact can be buffered by the double-sided adhesive tape 11 and the exterior member 6 is pushed up by the elasticity of the double-sided adhesive tape 11. Accordingly, the buffer mounting member 16 can be pushed up with respect to the main body case 5 along with this, whereby the buffer mounting member 16 can be lifted with respect to the main body case 5.

  For this reason, the buffer contact part 22b located in the upper end part of a pair of buffer part 22 of the buffer attachment member 16, and the upper side contact located in the upper end part of a pair of attachment projection part 15a of the band attachment part 15 corresponding to this Between the lower end portion of the pair of buffer portions 22 and the lower contact portion 15c of the corresponding band mounting portion 15 and between the connecting portion 23 of the buffer mounting member 16 and the corresponding band. The first to third gaps S <b> 1 to S <b> 3 can be provided between the holding projection 15 b of the mounting portion 15, and the buffer mounting member 16 can be reliably and satisfactorily secured to the band mounting portion 15. Since it can be displaced, an impact can be buffered reliably and satisfactorily.

  Further, in the wristwatch case 1, the guide locking projection 25 provided on the buffer mounting member 16 and the guide locking projection 25 of the buffer mounting member 16 provided on the exterior case 7 are arranged in the circumferential direction of the outer periphery of the main body case 5.

  In this case, when the buffer mounting member 16 is displaced with respect to the band mounting portion 15, the guide locking protrusion 25 can be displaced along the guide engaging hole 28, and therefore the buffer mounting member 16 is displaced. In addition, it is possible to prevent the exterior case 7 from being affected by the displacement of the buffer mounting member 16.

  In the above-described embodiment, the case where the exterior member 6 is configured to be temporarily fixed by being bonded to the upper surface of the main body case 5 by the double-sided adhesive tape 11 is described, but the double-sided adhesive tape 11 is not necessarily used.
