てなることを特徴とする伸縮支柱の安全装置。[Claims for Utility Model Registration] A safety device for a telescoping strut that extends and contracts in the vertical direction by a hydraulic cylinder operated by pressure oil supplied from a hydraulic pump rotationally driven by an electric motor, comprising: A detection sensor is provided for detecting a position inward from the end by an allowance length, and the allowance length is set to be larger than a maximum distance that the hydraulic cylinder will extend and move due to inertia after the electric motor is turned off. 1. A safety device for a telescopic column, characterized in that a control means is provided for turning off the electric motor when the detection sensor detects that the electric motor is being extended.
