Seal members extend from the openings toward the rotor. A tip end abutting portion of the seal member which abuts on the rotor functions as a seal and as a spring. The seal member is positioned by engagement with each of positioning portions provided on the openings and includes a rotation stopping portion that stops a rotation.
