Claims

[Scope of utility model registration request]

A support shaft, a support member to which the support shaft is fixed, an opening/closing member rotatably supported by the support shaft, and an elastic biasing member for biasing the opening/closing member to rotate in a predetermined direction. In the rotation opening/closing shaft support mechanism,
a surrounding member that is movably fixed to the opening/closing member and is fitted onto the support shaft to form a sealed space; a high-viscosity fluid sealed in the sealed space; and a surrounding member fixed to the inner peripheral surface of the surrounding member. A rotation opening/closing shaft support mechanism comprising a resistance member provided therein.
