Abstract: A pump fixing structure may include a pump including a pump part, motor part, and a fixing base. The pump part may include an outlet port, inlet port and an impeller. The motor part may rotate the impeller and may include a stator which includes a drive coil and a stator core; and a motor case integrally molded with the stator, the motor case structuring an outer peripheral face of the motor part. The outer peripheral face is formed in a substantially circular truncated cone face shape having a draft angle for drawing the motor case from a die. The pump part may include a fixed part fixed to the fixing base. The fixing base may include a bent metal plate and is provided with a motor support part disposed on a lower side. A buffer member may be disposed between the motor part and the motor support part.
