ROTATABLE APPARATUS

摘要

A rotatable apparatus includes a casing and a protector for closing an opening. The casing includes first and second casing faces intersecting at angle θ1. The first casing face is provided with an opening. The protector includes first and second protector faces abutting and intersecting each other at angle θ2. The protector is fixed to only the second casing face. The angle θ2 is larger than the angle θ1 when the protector is removed from the casing. The protector is attached to the casing in such a manner that the second protector face is fixed to the second casing face, and that the first protector face is elastically deformed so that an edge part of the first protector face, which is located on the side opposite to the second protector face, closely contacts the first casing face.
