<p>PROBLEM TO BE SOLVED: To prevent leakage of gasoline to the outside without any increase in a size as a whole. SOLUTION: A supporting shaft part 4a is formed on the inside face of a housing 1 facing a storage space 5. A cam shaft 11 reciprocating a plunger 19 in a pump unit 15 is arranged freely rotationally in the outer circumference of the supporting shaft part 4a. In the inside of the supporting shaft 4a, a supporting hole 4 is passed through from the tip face to the outside face of the housing 1. In the supporting hole 4b, a transmission shaft part 6b for a driving shaft 6 is arranged freely rotationally via slide bearings 8, 9. The transmission shaft part 6b is connected to the cam shaft 11 so as to be integrally rotated via an Oldam's coupling 14 and a joint member 13.</p> |
