Claims

[Scope of utility model registration request]

A telescopic arm is constructed by combining a hollow outer arm body and an inner arm body in a telescopic manner so as to be able to expand and contract by the operation of a telescopic cylinder provided along the outer side of the outer arm body; A hose reel is installed at the base end of the arm body, a hydraulic hose fed out from the hose reel is connected to a manifold block attached to the tip of the inner arm body through the inner arm body, and the face opposite to the inner arm body is connected to the manifold block. A telescoping arm device characterized in that a passage is formed from the block to the outer surface of the block.
