1. An indoor unit for an air-conditioning apparatus, the indoor unit comprising:
an air-deflector plate that adjusts a direction of air;
an air-outlet unit that has a base in which an air outlet through which air is blown out is formed and to which the air-deflector plate is attached such that the air-deflector plate covers the air outlet; and
an attachment portion to be attached to the air-outlet unit such that the air-deflector plate is rotatable,
the base of the air-outlet unit having a shaft-support portion that is located at the air outlet and at which a support opening port is formed such that the support opening port opens in an axial direction around which the air-deflector plate rotates,
the air-deflector plate having
a blade portion that is plate-shaped,
a first projection portion that projects from the blade portion toward the air outlet and at which a first shaft opening port is formed, and
a second projection portion that projects from the blade portion toward the air outlet and faces the first projection portion across the shaft-support portion and at which a second shaft opening port is formed,
the attachment portion having
a plate portion that is in contact with one face of the first projection portion in the axial direction and is larger in width than the first shaft opening port,
a shaft portion that extends from the plate portion and is inserted into the first shaft opening port, the support opening port, and the second shaft opening port, and
an engagement claw portion that is engaged with an other face of the first projection portion that is opposite to the one face,
the second projection portion having a notch that is cut along a direction in which the shaft portion extends and through which the shaft portion is exposed.
