摘要：
The cross sectional shape of an axial direction communicating path when viewed in the axial direction is flat in the circumferential direction, and the cross sectional area of the communicating path gradually decreases moving from the center of the cross section toward the both ends in the circumferential direction. When a sleeve and a cover member are bonded with an adhesive, the adhesive is actively made to flow into an adhesive inflow portion.
