Abstract: A non-pneumatic tire includes a plurality of springs. Each spring includes a first end portion, a second end portion, and an arching middle portion. Each spring is interwoven with at least one other spring thereby forming a toroidal structure extending about an entire circumference of the non-pneumatic tire. The toroidal structure is at least partially coated with an elastomer. One end portion of at least one spring is secured to a first bead spring adjacent a rim.

Abstract: 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.

Abstract: A non-pneumatic tire having a rim member 1, a ring member 3 disposed at an outer circumferential side of the rim member 1 and provided with a tread 2 on a circumferential face, and a plurality of link mechanisms 4 coupling the rim member with the ring member. Each of the link mechanisms 4 contains a pair of link members 7a, 7b formed of a link 5a, 5b which is connected at a first end with a side portion of the rim member 1 and which is swingable in the circumferential and meridian directions and another link 6a, 6b which is connected at a first end with a side portion of the ring member and 3 which is swingable in the circumferential and meridian directions with second ends of the links being hingedly connected one another to make the links swingable in the meridian direction. A spring member 9 imparting a stiffness against relative displacements in the radian, circumferential and width directions with respect to the rim and ring members 1, 3 is provided on the link mechanisms 4.
