PROBLEM TO BE SOLVED: To provide a balancer device which can reduce the drive loss and the size.SOLUTION: When a first shaft 23 is rotated to the left direction within the range of 90° from the state shown in Fig.6 (a), first and second sliders 25 and 26 and a second shaft 24 are rotated at the same angular velocity as the first shaft 23, as shown in Fig.6 (b)-(e), and a connection support shaft 43 supporting an external gear 27, that is, an Oldham center O3, turns on a circle C0 having a balancer center O as a turning center at the angular velocity twice the first and the second sliders 25 and 26. The external gear 27 supported by the connection support shaft 43 is meshed with an internal gear 52 whose number of teeth is twice, and rotates to a direction opposite from the first shaft 23, that is, the right direction, at the angular velocity twice, and a balance weight 28 is raised to the uppermost part in accordance with turning and rotating of the external gear 27. |
