Case, timepiece and fastening member

Abstract

A case by which impact resistance is enhanced and damages due to impacts are prevented, a timepiece equipped with the case, and a fastening member are provided. The case includes a case main body which has first insertion holes, a first exterior case which has second insertion holes coaxially corresponding to the first insertion holes and is arranged on the upper part of the case main body, and fastening members which have fixing portions to be fixed in the first insertion holes and fitting portions to be fitted into the second insertion holes. Each fitting portion is fitted into the corresponding second insertion hole while being deformed. Therefore, even if the wristwatch case is subjected to an external impact, the first exterior case does not rattle in the direction perpendicular to the axial direction of the fastening members, whereby the case main body is prevented from being damaged.
