わることがない。 As described above, according to the seal structure of the wheel support portion of a straddle-type four-wheel vehicle according to the present invention, a bracket is provided on one of the axle or the wheel axle, a pipe is provided on the other, and the bracket and the pipe are connected to each other. In a wheel support part of a straddle-type four-wheeled vehicle, which is connected via a king pin and is equipped with a wheel supported by the wheel shaft so as to be steerable with respect to the axle,
A flange portion along the outer peripheral surface of the pipe is provided on a ring portion of the housing interposed between the opposing surface of the bracket and the pipe, a cylindrical elastic member is attached to the outer peripheral surface of the flange portion, and a cylindrical elastic member is attached to the outer peripheral surface of the flange portion. A protrusion is provided along the periphery on one end surface of the elastic member that is in contact with the ring, and a protrusion that presses against the outer peripheral surface of the pipe is provided on the other end of the elastic member, so that between the bracket and the ring, and a complete seal is created between the pipe and the ring. Therefore, it is possible to prevent water, sand, etc. from entering the inside of the wheel support part through these gaps, so it is possible to prevent the occurrence of rust, etc.
Plating and painting of the housing can be omitted. Furthermore, since only the protruding portions of the elastic member come into pressure contact with the bracket, no unreasonable force is applied to the housing.
