PROBLEM TO BE SOLVED: To solve the problem that a suction utensil is reduced in size with ease because lead wire breakage is caused when a lead wire housing section is not installed in a joint pipe of the suction utensil, a rib for restricting how to route a lead wire is not installed in the lead wire housing section, and the length of the lead wire from the rib and lead wire housing section to an outlet from which the lead wire comes out toward the suction utensil side is not long.SOLUTION: A lead wire housing section 140 is formed in a joint pipe 120 of the suction utensil 5. A lead wire restricting rib 127 for restricting how to route a lead wire 130 is installed in the lead wire housing section 140. A plurality of lead wires 130 which reach a joint pipe pull-out port 128 after coming out to the suction utensil 5 side from the lead wire housing section 140, are arranged in a way that the lead wires 130 reach the joint pipe pull-out port 127 after detouring from the lead wire restricting rib 127 to an opposite side of side on which the joint pipe pull-out port 128 is installed. In this way, the routing length of the lead wires 130 is lengthened, so that the frequency of breakage of lead wires 130 due to turning of the joint pipe 120 can be reduced. |
