Then, rear wheels are mounted on the axle. At the rear wheel, an annular rim is fitted to the outer peripheral surface of the axle, and the rim is fixed to the axle, and then a rubber tire is assembled to the rim, or a rim on which the tire has been assembled is fixed to the axle.

Abstract

　La présente invention concerne une structure d'assujettissement de jante pour un véhicule de transport, dans laquelle un outil (25) de serrage est inséré depuis un côté extrémité d'un essieu (13) jusque dans un espace annulaire (δ) entre une surface (13a) périphérique externe de l'essieu (13) et une surface (19d) périphérique interne d'une jante (19x) tandis qu'une surface (25a) interne est superposée sur la surface (13a) périphérique externe de l'essieu (13) depuis de multiples emplacements ; et une surface (27) effilée de l'outil (25) de serrage est pressée contre une surface effilée de la jante (19x) afin d'assujettir la jante (19x) à l'essieu (13). Parmi la surface (13a) périphérique externe de l'essieu (13) et la surface (25a) interne de l'outil (25) de serrage, au moins la surface (13a) périphérique externe est pourvue d'une partie (30) structurale de guidage destinée à guider l'orientation de l'outil (25) de serrage inséré dans l'espace annulaire (δ) vers une orientation prescrite.
