Title:
BALANCER MECHANISM FOR ROTATING SHAFT
Document Type and Number:
WIPO Patent Application WO/2005/038292
Kind Code:
A1
Abstract:
A balancer mechanism (8) for a rotating shaft capable of easily and surely reducing a torque acting on the rotating shaft by allowing a balancing torque offsetting at least a part of the torque acting on the rotating shaft to act on the rotating shaft by using a gas spring, comprising the gas spring (20), a first connection part (40) for rotatably connecting the lower end part of the gas spring (20) to a shaft supporting mechanism (5) side stationary member (10) and a second connection part (45) for rotatably connecting the upper end part of the gas spring (20) to a rotating member (15) fixed to the left end part of the rotating shaft (3) at a position eccentric to the axis (A) of the rotating shaft (3).
