Abstract
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.
