A substrate transfer device includes a housing accommodating a carrier for storing a substrate, a carrier lifter moving the carrier in a vertical direction relative to an upper surface of the housing, a vertical stabilization unit connected to a lower part of the carrier lifter and reducing a vertical vibration of the carrier, a rotation stabilization unit connected to a lower part of the vertical stabilization unit and reducing rotation of the carrier, and a carrier holder connected to a lower part of the rotation stabilization unit. The carrier holder holds the carrier. The vertical stabilization unit includes an upper plate connected to the carrier lifter, a lower plate connected to the rotation stabilization unit, and a buffer disposed between the upper plate and the lower plate. The buffer contracts or relaxes to reduce the vertical vibration of the carrier.

A cushioning mechanism for a claw machine includes a rotating plate and a return member. The rotating plate has a pivot end and a movable end. The pivot end is pivotally connected to a base of a winding device of the claw machine in a manner that the movable end is movable relative to the pivot end. A first pulley of the winding device is disposed on the movable end. The return member is connected between the rotating plate and the base. The return member is configured for applying a return force to the movable end for the movable end to move toward an initial position, thereby cushioning a pivoting movement of the rotating plate and reducing vibrations of a control wire of the winding device during operation of the winding device.
