Claim 0:
1. A handle attachment comprising:
a base portion that can be attached to a portion of a wall surface of a door;
a flap portion that applies, as a result of a pulling operation, a pulling force to the door via the base portion;
a flap rotation mechanism that rotatably connects the flap portion with respect to the base portion around a rotation axis; and
a biasing member that biases the flap portion in a first rotation direction around the rotation axis with respect to the base portion,
wherein:
the flap portion includes a base end portion connected to the flap rotation mechanism and a distal end portion arranged at a position away from the flap rotation mechanism;
the first rotation direction is a direction in which the distal end portion of the flap portion separates from the wall surface of the door;
the flap rotation mechanism includes a pin member that extends along a first direction;
the base end portion of the flap portion includes a first leg portion having a first through-hole portion into which the pin member is inserted;
the first leg portion includes a first stopper that can come into contact with the base portion and a second stopper that can come into contact with the base portion;
the first stopper defines a first rotation limit for when the flap portion rotates in the first rotation direction;
the second stopper defines a second rotation limit for when the flap portion rotates in a second rotation direction that is opposite to the first rotation direction;
the base portion and the flap portion define a non-exposed region that cannot be externally accessed; and
the first stopper and the second stopper are arranged in the non-exposed region.
