Abstract:
1. A door opening and closing apparatus for a vehicle, comprising: a control unit configured to authenticate an identification signal outputted from a portable device carried by a user to recognize that the user is approaching the vehicle; a latch mechanism adapted so as to retain a vehicle door in a closed state relative to a vehicle body; an outside lever adapted to be provided within a space formed inside of the vehicle door so as to be positioned closer to an interior of the vehicle and linked to an outside handle adapted to be rotatably supported by the vehicle door; first and second locking levers together defining a locking lever switchable between an unlock state allowing an operation force applied to the outside handle to be transmitted to the latch mechanism and a locked state not allowing the operation force applied to the outside handle to be transmitted to the latch mechanism, the first locking lever locking lever including a stepped portion defining a recess in which a portion of the second locking lever is positioned; the first and second locking levers being rotatable relative to each other; a detection switch detecting an operation to the outside handle when the outside lever contacts the detection switch in response to a rotational operation of the outside lever; and a release device which actuates the latch mechanism when the control unit authenticates the identification signal outputted from the portable device carried by a user to recognize that the user is approaching the vehicle and when the rotational operation of the outside handle is detected by the detection switch while the vehicle door is in a locked state so that the latch mechanism releases retention of the vehicle door in the closed state.
