Abstract
There is provided a blower capable of maintaining output performance and adjusting a thrust acting in an axial direction of an impeller while reducing the number of parts. A flow path is formed in an intake port provided in a central part in the axial direction of the first housing and a blowing passage connecting the intake port and the discharge port as top surface portions of a housing-side shroud connecting to the intake port and an impeller-side shroud formed in the impeller which face the blowing passage are adjacent to each other in the radial direction.
