摘要： A weight (4) which is held by a weight holder (3) in a balancer has a pressing face (4b') which is pressed against a guide face (12a) provided along the circumferential direction of rotation of the weight holder (3) by centrifugal force generated by rotation of a rotary body. When the rotary body rotates, the weight (4) which is pressed against the guide face (12a) via the pressing face (4b') changes its position relative to the rotary body in the circumferential direction of rotation, whereby the weight (4) is disposed in a position in which it suppresses whirling motion of the rotary body. The guide face (12a) and pressing face (4b') are inclined relative to the axial direction of rotation so as to tend to outward side in the diametrical direction of rotation as tending to one side in the axial direction of rotation. The weight (4) is pressed against a receiving portion (7a') by component of the centrifugal force, in which the component acts along the guide face (12a) and pressing face (4b').

摘要： A balancer, comprising a weight (4) held by a weight holder (3) having a pressing surface (4b') pressed against a guide surface (12a) provided on the weight holder (3) in the rotating circumferential direction by a centrifugal force by the rotation of a rotating body, wherein the weight (4) pressed against the guide surface (12a) through the pressing surface (4b') during the rotation of the rotating body is disposed at a position for suppressing the swing of the rotating body by varying the position thereof in the rotating circumferential direction relative to the rotating body, the guide surface (12a) and the pressing surface (4b') are tilted relative to a rotating axis direction divergently toward one end of the rotating body along the rotating axis, and the weight (4) is pressed against a support part (7a') by the components of the centrifugal force along the guide surface (12a) and the pressing surface (4b').
