Claims

[Claims for Utility Model Registration] A first component whose end portions are rotatably supported by each of a pair of side plates spaced apart from each other constituting a support body.
a rotating body, and abuts on the first rotating body,
a second rotating body rotatably supported at each end by each side plate in a state where it can move toward or away from the first rotating body, and the second rotating body is one of the second rotating bodies; In a structure that is rotatably driven by a driving force being transmitted from the end side of the side plate, the support part of the side plate that supports one end of the second rotating body to which the driving force is transmitted is located outside the outer periphery of the side plate. The support part of the side plate is formed as a hole closed to the other end and supports the other end of the second rotating body to which driving force cannot be transmitted, and when the second rotating body is attached, the supporting part of the side plate supports the other end of the second rotating body. Through the notch through which
A structure characterized in that it is formed as a hole that is open to the outside of the outer periphery of a side plate.
