Abstract
Disclosed is a track belt for a snowmobile, which comprises a track belt main body, a core body arranged along a longitudinal direction of the track belt main body, reinforcing woven cloths disposed respectively in the outside and inside of the core body, cover layers for covering these reinforcing woven cloths and a plurality of horizontal rigid members placed at specified intervals in the longitudinal direction of the track belt main body and in the cross direction of the same. Overlapping of the reinforcing woven cloth is disposed respectively in the outside and inside of the horizontal rigid members. Reinforcing woven cloth is made by spirally winding a belt-like woven cloth having a specified width on a circumference of the track belt main body at a specified angle to the longitudinal direction of the track belt main body. Reinforcing woven cloths are made of tire fabric cords. A cord orientation angle of each of the tire fabric cords is set to a specified bias angle to the longitudinal direction of the track belt main body. End of the reinforcing woven cloths are butt-joined at both ends so as to have substantially an endless structure. A horizontal rigid member is disposed between the core body and the inner reinforcing woven cloth. Alternatively, the inner reinforcing woven cloth of the core body is folded on the core body or the outer reinforcing woven cloth in the longitudinal direction of the track belt main body on the circumference of the same.
