A wheel for a celestial running vehicle which enables the celestial running vehicle to sufficiently exhibit its desired running performance by maintaining a sufficient ground contact length, as well as reducing the wheel maximum width and the number of the sliding portions. The celestial body vehicle wheel (1) is mounted on a celestial body running vehicle and includes, a hub body (2) rotatable about a rotation axis, a grounding member (3) arranged radially outside of the hub body (2) and rotatable about the rotation axis while contacting a celestial body surface, and a load bearing device (4) arranged between the hub body (2) and the grounding member (3) for bearing radial load, the load bearing device (4) including, a plurality of first support members (5) arranged circumferentially to extend radially outward from the hub body (2) and terminate short of the grounding member (3), a plurality of second bearing members (6) arranged circumferentially to extend radially inward from the grounding member (3) and terminate short of the hub body (2), and elastic members (7) for connecting the first support members (5) and the second support members (6) to each other, wherein, under the radial load, the elastic members (7) are elastically deformed, and the first support members (5) and the second support members (6) are relatively displaced in directions approaching each other.
