ABSTRACT:
A slide arm for a work implement is provided, which is simply structured to obtain improved assembling precision thereby ensuring smooth operation. To this end, the slide arm is such that a plurality of tubular structural bodies (i.e., outer and inner tubes), each of which is formed by bending a one-piece plate into a shape having a substantially triangular cross-section and circular vertex portions, are telescoped one within the other with sliding members (i.e., plain bearing units and slide block pieces) interposed between them at the vertex portions and such that a sliding mechanism is disposed for sliding the tubular structural bodies.
