<p>PROBLEM TO BE SOLVED: To smoothly insert a linear member into a cylindrical small diameter part by providing a spiral rib spirally extending throughout the projecting direction of the cylindrical small diameter part and a linear rib linearly extending in the projecting direction of the cylindrical small diameter part in a form intersecting with the spiral rib. SOLUTION: Ribs 17, 18 which project from the inside peripheral surfaces of cylindrical small diameter parts 13, 16 and spirally extend throughout the projecting direction of the cylindrical small diameter parts 13, 16 are formed on the inside peripheral surfaces. Ribs 19, 20 which project from the inside peripheral surfaces and linearly extend in the projecting direction of the cylindrical small diameter parts 13, 16 in a form intersecting with the ribs 17, 18 are formed on the inside peripheral surfaces of the cylindrical small diameter parts 13, 16. Thereby, a wire harness and an auxiliary cable can be smoothly inserted into the cylindrical small diameter parts 13, 16, respectively, and the workability of the insertion work is improved. Additionally, the degradation of liquid- tightness can be prevented after the wire harness and the auxiliary cable are inserted.</p> |
