Abstract: The present invention aims to provide a bush that can suppress the wear of an elastic body due to repeated input in a perpendicular-to-axis broaching direction while maximizing degrees of freedom in designing the bush. A bush according to the present invention includes an outer cylinder, an inner cylinder, and an elastic body placed between the outer cylinder and the inner cylinder. The elastic body includes a broached part penetrating in an axial direction. A plate is placed between the outer cylinder and the broached part in a perpendicular-to-axis broaching direction. Part of the elastic body is located between the outer cylinder and the plate.

Abstract: A pneumatic tire in which a cavity resonance sound is reduced while punctures are easily repaired with a puncture sealant. The pneumatic tire has a fibrous region where short fibers are bonded onto an inner surface of the tire. A circumferential fiberless region where short fibers are not bonded onto the inner surface of the tire extends circumferentially between both ends of a tread ground contact area.
