A depth d1, d2 of each of the first recess 5 and the second recess 6 from a ground contact surface 2a is less than a groove depth D1 of the groove 3. The first recess 5 includes, in the ground contact surface 2a, a first opening 5a disposed at the first groove wall 3a, and a first end portion 5b extending substantially parallel to the first opening 5a at a position farthest from the first opening 5a. The second recess 6 includes, in the ground contact surface 2a, a second opening 6a disposed at the second groove wall 3b, and a second end portion 6b extending substantially parallel to the second opening 6a at a position farthest from the second opening 6a. The first end portion 5b and the second end portion 6b are disposed so as not to oppose each other through the groove 3.",
