1. A door opening/closing detection apparatus comprising:
a base mounted on a vehicle door;
a handle with one end portion axially supported in a rotatable way on the base with the vertical direction as an axis direction, with other end portion having a gripping portion exposed to be operatable from the door to an interior side of the vehicle, and when operated, rotates the gripping portion from a neutral position to a pull operation position in which the door is rotated in a closing direction or from the neutral position to a push operation position in which the door is rotated in an opening direction;
a detection unit for detecting the push operation position and pull operation position of the handle,
wherein the detection unit is actuated by the handle in the push operation position and pull operation position;
wherein the detection unit has a pair of switches, and
wherein the handle comprises:
a handle main body with one end portion axially supported in a rotatable way by the base, and has the gripping portion at the other end; and
a sub-handle that is axially supported in a rotatable way on the base coaxially with the handle main body, rotates in conjunction with the handle main body when the handle main body rotates from the neutral position to one side in the direction of rotation, and is held in the neutral position when the handle main body rotates from the neutral position to the other side in the direction of rotation, being uninterlocked from the rotation of the handle main body,
wherein the handle main body has a main body side operation portion that activates one of the pair of switches when rotating from the neutral position to the other side in the direction of rotation; and
the sub-handle has a sub-side operation portion that activates the other of the pair of switches when the handle main body is rotated from the neutral position to one side in the direction of rotation.
