置操作機構。[Scope of Claim for Utility Model Registration] A cage is mounted along an elevating support body provided with a rolling mesh type rack gear so that the meshing part is oriented parallel to the front surface of the frame, through the elevating frame so that the cage can be raised and lowered by rolling meshing drive with the rack gear. In the installed small construction elevator, the upper part of the lifting frame is equipped with a locking piece with a roller to which a torsion spring force is applied so that it plunges between the teeth of the rack gear when the locking force is removed; Operation spring force of the stop piece A locking pawl is mounted on one axis and disposed via a support frame, and the locking pawl is provided with a lever link whose tip is normally engaged, At the rear end of the lever link, there is an operating rod for applying the locking force of the locking pawl, and an end of an emergency manual operation rope that is stretched around a guide roller around the upper part of the cage so as to suspend the puller. A safety device operation mechanism for a small-sized construction elevator, characterized in that a limit switch is provided near the locking pawl or the locking piece to cut off the driving power when the locking piece is locked.
