Description of the Related Art A vanity mirror is a mirror that is mounted in a vehicle interior for cosmetic purposes or the like, and is generally mounted on the back of a sun visor disposed above and in front of a driver's seat and a passenger's seat. The vanity mirror has a mirror holder in which the mirror is fixedly arranged, and a cover (lid) rotatably connected to the mirror holder and arranged to be openable and closable with respect to the mirror. The surface is exposed, and the cover is closed when not in use to cover the mirror surface so that it does not interfere with the use of the sun visor. The vanity mirror has a sense of moderation when opening and closing the cover (a function to switch between the opening direction biasing force and the closing direction biasing force during the opening / closing operation to maintain the open or closed position).
In many cases, a spring is interposed between the mirror holder and the cover in order to provide the mirror.

きる。According to the cover opening / closing mechanism as described above, the leaf springs 84, 85 having a substantially J-shape are positioned below the rotating shaft 102 with the curved portions 110 of the leaf springs 84, 85 facing downward.
The 85 longer linear portion 106 is disposed on the side facing the cover 46, and is biased in a state of being folded back toward the rear side of the mirror body 44 rather than in a posture parallel to the surface of the mirror body 44 so as to contact the cam 88. As a result, even if the length L2 (see FIG. 7C) of the leaf springs 84 and 85 is increased, the arrangement dimension in the mirror body thickness direction can be made shorter than that of the inverted V-shaped leaf spring 22 of FIG. Thus, the mirror body can be made thin, and the entire vanity mirror can be thinned.
