Claims

[Scope of utility model registration request]

In the balancer, a torsion bar is provided on a rotating body supported so as to be rotatable around a substantially horizontal axis, and the rotation moment due to gravity of the rotating body is canceled by the reaction force of the torsion bar. The shaft portion of the torsion bar is made eccentric with respect to the axis that is the center of rotation of the rotating body, and the contact portion provided on the torsion bar is brought into contact with the cam plate in order for the torsion bar to obtain a reaction force. A balancer for a rotating body, wherein the contact portion moves on a cam surface of a cam plate as the rotating body rotates.
