業車両用アタツチメント高さ検出装置。[Claims for Utility Model Registration] A chain is disposed along the vertical direction on an inner mast that is moved up and down with respect to an outer mast, and a lift encoder is provided on the outer mast, and a sprocket of the lift encoder is connected to the chain. In an apparatus for detecting the height of an attachment by causing a sprocket of the lift encoder to roll through the chain due to the vertical movement of the inner mast, at least one end of the chain is engaged with the inner mast. At the same time, the chain is coupled to the mast so as to be movable up and down, and a biasing means is provided for biasing the chain in the tensile direction.The sprocket of the lift encoder is spaced apart from a line connecting both ends of the chain, and the chain is An attachment height detection device for an industrial vehicle, characterized in that at least two guide members that are bent and engaged with the lift encoder sprocket are disposed on the upper and lower sides of the lift encoder sprocket.
