Patent ID: 8708552

Claim:
A shock damping structure for a wristwatch, in which a damping member provided between a wristwatch case and a wristwatch module encased within the wristwatch case damps an external shock applied on the wristwatch case by a shock absorbing operation of the damping member, the damping member comprising: a holding member having a ring-shaped upper surface portion and a cylindrical portion, and disposed between an inner peripheral surface of the wristwatch case and an outer peripheral surface of the wristwatch module; a first shock absorbing member disposed to cover a predetermined part of an upper surface of the upper surface portion and outer peripheral surface of the cylindrical portion of the holding member, deformed elastically when an external shock is applied on the wristwatch case, and absorbing the shock elastically; and a second shock absorbing member disposed to cover another part of the upper and outer peripheral surface portions of the holding member, the other part excluding the predetermined part, getting the external shock earlier than the first shock absorbing member when the external shock is applied on the wristwatch case, changing its volume in accordance with a shock force of the external shock, and absorbing the external shock, wherein the first shock absorbing member includes an upper surface portion and side leg portions formed integrally with each other to extend along the upper surface of the upper surface portion and outer peripheral surface of the cylindrical portion of the holding member, and further including cut-out portions at positions corresponding to 3, 6, 9, and 12 o'clock positions of the wristwatch case, and wherein the second shock absorbing member is made of a gel-like material whose main component is silicone and includes bending portions and side leg portions formed integrally with the bending portions, the bending portions and side leg portions being arranged at the cut-out portions of the first shock absorbing member to extend along the upper surface of the upper surface portion and outer peripheral surface of the cylindrical portion of the holding member.
