This air-conditioning device () for a vehicle comprises a flow path width adjustment portion () that is provided at an inlet portion (BA) of a ventilation flow path (B) so as to be connected to the inner surface (a) of a first side wall (), the flow path width adjustment portion () having an upper end connected to a fan mounting portion (), extending downward, and being located between a third wall () and a nose portion () in the (Y) direction. The nose portion () has an inclined portion (A) that is inclined with respect to the third wall () such that the width of the inlet portion (BA) increases in the (Z) direction from the inlet to the outlet of the inlet portion (BA) of the ventilation flow path (B). In the (Z) direction, the flow path width adjustment portion () is formed so as to narrow the width of the inlet portion (BA) of the ventilation flow path (B) in the (Y) direction.
