A device for carrying out motional training by continuously flexing and extending a joint of the body comprises a mounting piece for mounting the device in the vicinity of a joint, a drive unit arranged on the mounting piece including a reversable rotation motor having a motor output shaft, a manual switching clutch connected to the motor output shaft, a power transmission connected to the motor output shaft and a transmission output rotating shaft, a swinging arm having a base portion mounted on the mounting piece, and a free end portion of the device including another mounting piece for mounting the free end side of the device to a portion of the shaft body in front of a joint. The swinging arm is coupled to the transmission output rotating shaft and subjected to a reciprocating swing motion during regular and reverse rotation of the transmission output rotating shaft. A movable range setting copying mechanism sets the first swing end and the second swing end of the swing arm. The movable range setting mechanism includes a movable range setting dial located coaxially with the transmission output rotating shaft. A switch is located in the vicinity of the transmission output rotating shaft for controlling the rotational direction of the motor. The movable range settings dial is swung by manually moving the swing arm in a clockwise direction and counterclockwise direction so as to specify the range of motion of each swing.
