<p><P>PROBLEM TO BE SOLVED: To provide a tank integrated type pump capable of easily and surely connecting a pump housing and a tank without requiring a special parts. <P>SOLUTION: In the tank integrated type pump constructing a flow channel for supplying fluid to a pump housing 1 from a tank 2 with combined with a port 7 provided on one of the pump housing 1 and the tank 2, and a cylinder part 10 provided on another, a flange part 9 is provided on an outside of one of opposing surfaces for combining the pump housing 1 and the tank 2, and holding pieces 12, 13 are erected on another opposing surface side. The pump is constructed so that the holding pieces 12, 13 are positioned at an outside of the flange part 9 when the cylinder part 10 and the port 7 are combined, and is constructed so that the holding pieces 12, 13 deform to the flange part 9 side by approaching force and the flange part 9 is held by the holding pieces 12, 13 when opposing surfaces of the pump housing 1 and the tank 2 are put close. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
