PROBLEM TO BE SOLVED: To improve mounting ability of the dust cover of a power transmission member. SOLUTION: In a four-wheel drive type four-wheeled buggy vehicle, the output shaft of an engine, the bevel gear 22 of a differential apparatus 6 on the front wheel side, and a front wheel propeller shaft 5 are intercoupled through a coupling tube 21, a large diametric part 25 is situated on the outer periphery of the front wheel propeller shaft 5 in the vicinity and in the rear position of a rear end opening part 21b of the coupling tube 21, and a band 26 is tightened with the two ends of a dust cover 20 covered by its outer peripheral surface and the outer peripheral surface of the rear end opening part 21b. The large diametric part 25 is formed approximately in the same size as the outside diameter of a spline 23 formed at the tip of a front wheel propeller shaft 5, and the shaft is made slenderer than the spline 23. In case of intercoupling of the coupling tube 21 and the front wheel propeller shaft 5, the spline 23 can pass through the opening part 21b on the free side of the dust cover 20 in a state that the dust cover 20 previously covers the dust cover 20. After coupling of the spline, the free side of the dust cover 20 is covered by the outer periphery of the large diametric part 25 and tightened by a band 26. COPYRIGHT: (C)2004,JPO&NCIPI
