1. A door handle apparatus for a vehicle, which is assembled to a door panel of the vehicle, the door handle apparatus comprising:
a grip that is allowed to be gripped from a vehicle exterior of the door panel, the grip being supported so as to be rotatable around a shaft extending in a predetermined direction, rotating in a first direction from a first state in which an outer surface of the grip is located in a same plane as an outer surface of the door panel to be transitionable to a second state in which the grip protrudes from the outer surface of the door panel, and rotating in a second direction opposite to the first direction from the second state to be transitionable to the first state;
a biasing device that causes the grip to rotate in the second direction; and
a resistance force generation device that generates a resistance force against an external force causing the grip to rotate in the second direction, the external force acting on the grip from the vehicle exterior,
wherein the biasing device is a spring,
the resistance force generation device includes:
a first lever that is engageable with the grip;
a stopper that is engageable with the first lever; and
an electric actuator that in the second state, engages the first lever with the grip and engages the stopper with the first lever to restrict a rotation of the grip in the second direction via the first lever, and retracts the stopper from the first lever to release the engagement between the first lever and the stopper when a predetermined condition is satisfied, and
wherein the stopper includes a guide plate including a slit-like opening, and a head portion including a base portion and a flange portion that are orthogonal to each other, a cylindrical protrusion provided on a surface of the base portion is inserted into the slit-like opening, and a thickness direction of the flange portion being parallel to an extending direction of the slit-like opening.
