Abstract: A vehicle wheel, which is divided in an axial direction of a tire into two pieces which are an in-side half wheel and an out-side half wheel that are connected to each other and fixed to an axle hub, includes wheel coupling bolts joining a mating surface of the in-side half wheel and a mating surface of the out-side half wheel together, and hub bolts joining the out-side half wheel and the axle hub together. The wheel coupling bolts and the hub bolts are respectively screwed into nuts from the out-side half wheel side.

Abstract: Provided is a core (10A), in which split pieces (10P) adjacent to each other in a circumferential direction are coupled by a coupling pin (11), an axial direction of which is disposed in a width direction of the split pieces (10P), at a radial inner circumferential side thereof, and split surfaces (10a, 10b) formed by both of the split pieces (10P, 10P) include a first load receiving surface (10c) and a second load receiving surface (10d) having a predetermined angle with respect to a radial direction at a radial outer circumferential side from the coupling pin (11).

Abstract: A travel device includes a bogie frame (11) configured to support an axle (5) to which a wheel (3) is attached, a suspension frame (15) disposed close to a center of a vehicle body (1) with respect to the bogie frame (11) and having a support section (16) extending downward from the vehicle body (1), and an upper link (14a) and a lower link (14b) configured to connect the support section (16) and the bogie frame (11) to relatively move the bogie frame (11) with respect to the support section (16) in a vertical direction. In the lower link (14b), a position (11b) at which the lower link (14b) and the bogie frame (11) are connected by pin coupling is disposed lower than a position (15b) at which the lower link (14b) and the support section (16) are connected by pin coupling.
