Abstract

PROBLEM TO BE SOLVED: To miniaturize a unit assembling plate, and also, improve the workability when an elastic member for vibration isolation is fitted by constituting a pump unit in such a manner that the width of the unit assembling plate can be made narrower than the longitudinal width of a pump attaching plate. SOLUTION: An elastic member 48 for vibration isolation is respectively fitted on horizontal flanges 43, 44 being bonded on an edge part at the deep end side, and an edge part at the forward side of a pump attaching plate 41. In this case, a slip-preventing protuberance 47 on the horizontal flanges 43, 44 is engaged with both end edges of a deep end part 48c of a slit 48a of the elastic member 48, and the elastic member 48 is prevented from slipping off. Therefore, even when the elastic member 48 is not firmly fitted, the elastic member 48 does not accidentally slip off. Also, a housing groove 14 is formed on a housing 11, and the elastic member 48 on the forward side is brought into contact with the groove wall on the forward side of the housing groove 14, and for this reason, the width of a unit assembling plate 51 is not required to be extended to a position being equivalent to the elastic member 48 on the forward side, and the unit assembly plate 51 can be miniaturized.
