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.
L'invention concerne un bras coulissant d'une machine à travailler que l'on peut manoeuvrer en douceur en simplifiant une structure et en augmentant la précision d'un ensemble. Un corps structural tubulaire (tube externe, tube interne), en forme généralement triangulaire en coupe transversale et arciforme à chaque partie sommet de la coupe transversale par pliage d'une plaque, est combiné avec un logement par le biais d'un élément coulissant (unité d'appui coulissante et pièce bloc coulissante) placé à chaque partie sommet. Enfin, l'invention concerne un mécanisme coulissant qui permet de faire coulisser le corps structural tubulaire.
