Claims

[Scope of utility model registration request]

In an opening/closing body structure in which an opening/closing body is attached to a fixed side member by a support shaft so that the opening/closing body can be opened and closed, the opening/closing body is closed by a spring member provided on the fixed side member, and a spring member provided on the opening/closing body and acting on the spring member. a first cam surface that acts on the spring member to generate a moment that biases the opening/closing body in the closing direction and a moment that biases the opening/closing body in the opening direction; It is characterized by comprising a cam means having a second cam surface that sets and maintains an open position within a range, and a third cam surface that acts on the spring member and biases the opening/closing body in the opening direction. Opening and closing body structure.
