案登録請求の第１項記載の揚降装置。[Scope of Claim for Utility Model Registration] 1. An outer frame and a motor that is installed on the outer circumferential surface of the outer frame and can be started and stopped in forward and reverse rotation at will, and is installed inside the frame via a coaxial coupling. There is a rotary screw that can rotate, and a nut that can reciprocate in the axial direction in response to the forward and reverse directions of this rotary screw. , two shafts connected to each other through a joint attached to a nut and slidably supported by sliding bearings, etc., slide in the axial direction within the frame, and these two shafts move outside the frame. It can protrude and perform lifting and lowering movements, and at the end of the lifting and lowering processes in this lifting and lowering movement, the position of the sliding shaft, the position of the nut, the amount of rotation of the rotation screw and motor are detected, and the motor is automatically stopped. without the need for a detection sensor device to
After reaching the end point of the lifting and lowering process described in the previous section, a fixed position idle mechanism is installed in the power transmission device between the rotary screw and the nut so that the motor and the rotary screw can idle regardless of the reciprocating movement of the nut. A lifting device characterized by the addition of. 2. The utility model as set forth in item 1 of the utility model registration claim, characterized in that by providing a detection sensor device to detect the position of the sliding shaft, an intermediate position of the reciprocating movement of the sliding shaft can be arbitrarily selected and stopped. Lifting device.
