PROBLEM TO BE SOLVED: To provide a training device capable of adjusting an interval between both hands at respective positions of reciprocating movement of two operation parts, in which shapes of the two operation parts fit palms of hands, at respective positions of reciprocating movement.SOLUTION: A training device comprises: support members 34B for supporting two operation parts 100 in a direction of resisting a load, and a direction where a load acts, so as to freely move by reciprocating movement; and two rotary members 110 rotatably supported to the support member, and respectively rotate the respective operation part to the support member around two first axes X1 vertical to a virtual rotation plane PL. Each of the two operation parts is configured so that, a barycenter P1 on a cross section parallel to the virtual rotation plane is positioned at a position eccentric from the first axis X1, and when an axis parallel to a rotation radius direction on the virtual rotation plane is a second axis X2, a contour length on a cross section orthogonal to the second axis X2 is different on plural positions A1-A3 on the second axis where lengths R1-R3 being lengths of the rotation radius from the first axis.SELECTED DRAWING: Figure 5 |
