A pump installation member has a first and second mutually discrete support members to be secured to predetermined installation portions of the first and second pump units, respectively. The pump installation member further has installation elastic members to be set between the first and second support members and the installation surface. The installation elastic members are elastically deformable as the first and second support members are displaced toward the installation surface when the first and second support members are fastened to the installation surface.

Pump installation member

A connecting pipe has a connecting pipe portion having, at the opposite ends thereof, connection opening end portions. The connecting pipe has a bendable portion provided between the opposite ends of the connecting pipe portion to allow the connecting pipe portion to be bent relative to the longitudinal axis of the connecting pipe portion. The connecting pipe further has rigid portions extending from the bendable portion to the connection opening end portions, respectively. The rigid portions have a higher rigidity than the bendable portion. Bending the connecting pipe portion at the bendable portion allows the connection opening end portions at the opposite ends to be fitted to associated pipe end portions, respectively. The connecting pipe portion has an elastic restoring force to maintain the state where the connection opening end portions are fitted to the associated pipe end openings, respectively.
