スタッド、及び、タイヤ
Document Type and Number:
Japanese Patent JP6530643
Kind Code:
B2
Abstract:
The invention provides a stud capable not only of keeping or reducing the total weight of the studs for a tire, thus observing the stud weight regulation, but also of improving the anti-stud-loss performance. The stud has a columnar body section, a pin section disposed on one end of the body section, and a flange section disposed on the other end of the body section. The pin section is formed in a shape having a length direction and a width direction. And the pin section, the body section, and the flange section in orthographic projection satisfy 0 ¦ (SM/HM) < 1.0 and 0 < (HM-SM) /FM < 0.7 where SM is a projected area difference between the flange section and the body section in the width direction of the pin section of the stud, HM is a projected area difference between the flange section and the body section in the length direction of the pin section of the stud, which is orthogonal to the width direction of the pin section, and FM is a maximum sectional area of the flange section orthogonal to the central axis of the stud.
