A register includes an annular fin that can improve the directivity of air conditioning air while suppressing increase in the number of parts. A front fin includes an annular-shaped annular fin portion. A bezel has upstream side inclined surfaces formed on inner peripheral surfaces facing with each other in the shorter side direction (vertical direction) of an air blow outlet. The upstream side inclined surfaces incline toward a direction of approaching the annular fin portion from an upstream side toward a downstream side of an air blowing direction. An air conditioning air flowing in the air blowing direction is guided to the annular fin portion side by the upstream side inclined surfaces.

A latch mechanism is configured to be shifted between a closed state in which a glove door is held on a compartment body at a closed position and an open state in which the glove door is not held on the compartment body. An operation lever is operated to shift the lock mechanism from the closed state to the open state. When the latch mechanism is shifted to the closed state, the first engaging member is engaged with the engagement hole. When the latch mechanism is shifted to the open state, the first engaging member is disengaged from the engagement hole. The compartment body includes an operation restriction wall that restricts operation of the first engaging member from the side surface of an instrument panel or the side surface of the compartment body so that the first engaging member is not disengaged from the engagement hole.

An EV priority switch is configured to allow a user to request a change between an EV priority mode and an HV mode. If an SOC of a power storage device is less than a first threshold value when the change to the HV mode is requested from the EV priority switch during the EV priority mode, an ECU changes the running mode to attain the HV mode and controls the SOC to be close to the SOC at the moment of a request for the change to the HV mode. If the SOC is greater than or equal to the first threshold value, the ECU maintains the EV priority mode. If the SOC reaches a second threshold value less than the first threshold value, the ECU forcefully changes the running mode to attain the HV mode.

A power transmitting device includes power transmitting coils, which contactlessly transmit electric power to a power receiving coil, and a switching device. When the power receiving coil is a solenoid coil, the switching device connects the power transmitting coils in parallel with each other such that magnetic fluxes generated inside the power transmitting coils flowing in the same direction along a winding axis. When the power receiving coil is a circular coil, the switching device connects the power transmitting coils in series with each other such that magnetic fluxes generated inside the power transmitting coils flowing in opposite directions along the winding axis.

A parking assist system for a vehicle includes a target position setting unit setting a vehicle target parking position on the basis of a coil type and position of a power transmitting unit. When the coil type is a composite coil having a configuration such that an annular coil wound to surround a first axis and a solenoid coil wound to surround a second axis intersecting with the first axis are serially connected, the target position setting unit sets the target parking position such that a center of a power receiving unit mounted on the vehicle is located at a predetermined distance from the first axis along the second axis. The solenoid coil is set at a position with respect to the annular coil such that the first axis extends through a side face center portion of the solenoid coil.
