Abstract
The invention relates to a pump motor for a vehicle, wherein when integrally forming the housing of a motor pump, in which the pump accommodating portion is made larger in diameter than the motor accommodating portion, by using metal dies, ventilation holes that communicate from the base end side of the housing to the motor accommodating portion are formed without making the motor accommodating portion of the housing larger in diameter, wherein projections are formed so as to be continuous to the base end side at the portion opposed to the pump accommodating portion on the outer circumferential surface of the housing, and the ventilation holes are formed to incline inwardly so that they reach from the base end side of the projections to the inside of the motor accommodating portion.
