摘要：
A massage device includes a base, a drive unit, and a transmission unit. The drive unit is coupled to the base. The transmission unit is disposed at one side of the base. The drive unit includes a drive member to drive a rotary shaft for driving massage members. One end of the rotary shaft is provided with a unidirectional bearing and a first bevel gear. The unidirectional bearing is able to control the rotation of the first bevel gear. The transmission unit includes two positioning blocks and a worm shaft connected between the two positioning blocks. The worm shaft is provided with a second bevel gear and a movable member thereon. The first bevel gear meshes with the second bevel gear. When the first bevel gear is rotated, the second bevel gear is driven to link other parts so that the drive unit can slide on the base.
