PROBLEM TO BE SOLVED: To bring friction gears for providing driving force of iron wheels from tires as driving wheels into contact with right and left tires under an equal pressing condition. SOLUTION: In a rail and land vehicle 1 including both the tires 21, 22 and the iron wheels 31, 32, rotation of the friction gear 11b rotated by being brought into contact with the tire of the drive wheel is input into an input shaft 521 provided to a hydraulic pressure generation means 51 generating hydraulic pressure for driving drive iron wheels. The friction gear 11b is rotatably attached to a hollow shaft 40 attached to a swing plate 12b. One end 131 of a shaft 13b passed through the swing plate 12b through a through-hole 121 formed in the swing plate 12b and loosely fitted into the hollow space 45 of the hollow shaft is connected to the friction gear 11b through a universal coupling 18, and also the other end 132 of the shaft 13b is connected to the input shaft 521 of the hydraulic pressure generation means 51 through a universal coupling 19. Further, the through-hole and a hollow shaft attaching bolt hole formed around the through-hole are formed as a long hole. COPYRIGHT: (C)2011,JPO&INPIT
