A grommet is provided which can reduce an insertion load without decreasing a disengagement load of an inserting member. The inserting member, having a leg portion and a head portion formed by increasing the diameter of a tip end of the leg portion, is inserted from one end side of a body portion of the grommet into an insertion hole and attached to an inserted member with the grommet interposed. On the one end side from a groove portion formed in an outer circumferential surface of the body portion, a diameter of the insertion hole is equal to or larger than a diameter of the head portion. On the other end side from the groove portion, the grommet has a small diameter portion in which a diameter of the insertion hole is smaller than the diameter of the head portion and is equal to or larger than a diameter of the leg portion.

Grommet

A shield member () is arranged on the rotor end face () of an electric rotating machine (). As the rotational velocity of a rotor () increases, the shield member () moves outward in the radial direction of a rotating shaft () to cover a part of the opening () of a slot (). The shield member () controls inflow of lubricant from a portion in the axial-direction of the rotating shaft () on the outside of the rotor end face () to the slot (). Rotational resistance of the rotor () caused by stirring of lubricant can be reduced during high velocity rotation of the rotor ().

Electric rotating machine

When it is predicted that a request for a parking lock operation is likely to be received, an actuator of a parking mechanism is controlled to perform standby processing for bringing the parking mechanism into a standby state immediately preceding a lock state to wait for the request for the parking lock operation.
