Abstract: A leg training equipment has a base fixed in place, a support portion configured to support a part of a user's body, and a coupling mechanism provided between the base and the support portion. The coupling mechanism movably couples the support portion to the base such that a load applied to a leg of the user by the user's own weight changes by a relative positional displacement between a foot position and a position of center of gravity of the user. In addition, the coupling mechanism limits a movable direction of the support portion such that at least when the load applied to the leg increases, a direction of the relative positional displacement between the foot position and the position of center of gravity is substantially limited to a direction of flexion and extension of knee joint. Thereby, it is possible to efficiently provide the user with an exercise that applies less load on the knee joint.

Abstract: A drive device has a motor for generating a drive force, a power transmission unit for transmitting the force generated by the motor to first and second foot support tables, thereby moving the foot support tables, and a control unit for controlling the motor. The power transmission unit is connected to an output shaft of the motor. The power transmission unit has a left foot reciprocation mechanism for reciprocating a left foot support table, a right foot reciprocation mechanism for reciprocating a right foot support table, and a power divergence unit for diverging the force of the motor into the reciprocation mechanisms and transmitting the force thereto. The power transmission unit alternately transmits the rotation force of the motor to the left and right foot support tables, thereby causing the left and right foot support tables to alternately move in a forward and backward direction in increments of one reciprocation.
