The valve case has the annular opposing surface capable of opposing to the free end so as to form the gap therebetween, and the guide surface that is positioned on one side of the opposing surface in the axial direction, the guide surface being continuous with the part of the opposing surface in the circumferential direction. The guide surface is inclined in the direction away from the valve body as the distance from the opposing surface is increased.
