Abstract: Cylinders each having open end and an internal engagement section in the mid-portion thereof are fixed in holes bored on an outer circumferential face of a tire tread. In each cylinder, a stud passing through a through-hole of the engagement section and having an expanded section at the front end thereof is inserted with play. The stud is biased toward the front end of the cylinder by a spring provided between a lid closing the rear opening of the cylinder and the expanded section. When the tire slips on a snow- or ice-covered road, the stud inclines and a large-neck section of the front end of the stud engages the rim of the cylinder to maintain the stud in a projected state. The projected large-neck section bites the surface of the road to prevent slippage. On a dry road, the stud 32 is pushed into the cylinder by the weight of the vehicle against the elasticity of the spring.

Abstract: The stud unit of the present invention is used for skid-proof tires of vehicles. On a snow- or ice-covered road, a force acts on a front end of a stud contacting the road when the vehicle is braked or accelerates and the tire treads consequently slip, so that the stud is kept projecting from a cylinder due to mutual engagement of the stud and the cylinder. On a dry road, the treads of the tire hold the road without slipping, so that no force acts on the stud to cause it to incline, and the stud can smoothly retract into the cylinder.
