Claims

[Scope of Claim for Utility Model Registration] 1. In an underground type lift in which a hydraulic cylinder is housed under the floor in a vertical position with the piston rod protruding directly above, and a vehicle support is provided at the tip of the piston rod, the hydraulic cylinder is located on the side of the hydraulic cylinder. A rack is hung below the floor surface, and the upper end of a ram loosely fitted into the cylinder is fixed to the tip of the piston rod, and a force is applied to the lower part of the ram to press the toe against the tooth surface of the rack. A buried lift comprising a locking claw attached to the rack so that the rack and the locking claw can be locked, and a mechanism for releasing the lock between the rack and the locking claw. 2. The unlocking mechanism fixes a rotating arm having an abutting pin at the tip to the rotating shaft of the locking pawl, and brings the abutting pin into contact with a vertical bar linked in parallel with the rack, so that the locking claw is rotated vertically. According to claim 1, the abutting pin is guided toward the vertical bar side by the pressing force of the locking claw or pushed back by the horizontal movement of the bar in order to engage and disengage the bar. buried type lift. 3 The hydraulic cylinder is placed in an inverted vertical position so that the piston rod protrudes directly below, the lower end of the piston rod is fixed, and the ram is housed under the floor so that it can move forward and backward directly upward, and a vehicle support is provided at the upper end of the ram. In a buried type lift, a rack is installed vertically below the floor surface on the side of the hydraulic cylinder, and a locking pawl is attached below the ram to apply a pressing force to the tooth surface of the rack at the tip of the ram. An underground lift comprising a rack and a locking pawl in a lockable position, and further provided with a mechanism for releasing the lock between the rack and the locking pawl.
