Title
(EN) SLIDE ARM FOR WORKING MACHINE
(KO) 작업기의 슬라이드 아암
Abstract
(EN)

PURPOSE: To provide a slide arm of a working machine having a configuration permitting a smooth operation by enhancing assembling accuracy by simplifying the construction.

CONSTITUTION: A single sheet plate is bent and its cross section is made almost triangular with the apex portions 4a, 4b and 4c made to a circular arc shape in this cylindrical structural body (outer cylinder 2, inner cylinder 3); and the cylindrical structural body is assembled to a telescopic tube by interposing slide members (a sliding bearing unit 8 and a slide block piece) provided at the apex portions 4a, 4b and 4c and a mechanism sliding the members is equipped.
