Revolving structure for glasses part
First Claim
1. A revolving structure for a glasses part for revolving a second member to a first member, comprising:
- a rotational shaft provided on the first member; and
a cylindrical member with elasticity which is press-fitted on the rotational shaft externally, wherein the cylindrical member is fitted to the second member in a state that the cylindrical member has been pressed by a pressing member, and the cylindrical member is prevented from being rotated even if the rotational shaft of the first member is rotated.

Abstract
A revolving structure for a glasses part for revolving a second member to a first member is provided with a rotational shaft provided on the first member and a cylindrical member with elasticity which is fitted on the rotational shaft externally, where the cylindrical member is fitted on the second member in a state that the cylindrical member has been pressed by a pressing member and the cylindrical member is not rotated even if the rotational shaft of the first member is rotated. The second member has a groove portion a in which the cylindrical member is fitted and an arc face for contact with a circumferential face of the cylindrical member is formed on the groove portion. Accordingly, a revolving structure for a glasses part where when a rotational shaft is rotated, sufficient frictional resistant force is provided and entrance of dust or the like is prevented.
