<p>PROBLEM TO BE SOLVED: To provide a vehicular rear axle structure in which flexural stiffness of an axle pipe can be raised while suppressing stress concentration to the connecting part of an opening end of the axle pipe and a spindle and which is excellent in endurance.SOLUTION: A vehicular rear axle structure comprises an axle pipe 7, spindles 6a, 6b which are welded to opening ends 7a, 7b of the axle pipe and support wheels 3a, 3b as rotatable, and spring seats 12a, 12b which are fixed at end parts of the axle pipe and receive a coil spring 13 for suspension interposed between the axle pipe and a vehicular body. The spindle includes an extension part 22 which is extended from the opening end of the axle pipe to below the spring seat. The extension part is configured so as to contact to the inner surface of the axle pipe and receive the load transmitted to the axle pipe through the spring seat from the coil spring 13 for suspension.</p> |
