In a communicating portion where the front side circumferential groove, the rear side circumferential groove, and the axial groove communicate with one another, a depth of the front side circumferential groove is larger than a depth of the rear side circumferential groove, whereby a step portion in a depth direction of the circumferential grooves is formed.
