The part of is exposed to the outside. And
When welding the fitting part between the bushing 10 and the pole 9,
Since the heat is dissipated from the upper spiral protrusion 13, the lower annular protrusion 11 is less likely to be heated than in the conventional case. Therefore, the annular protrusion 11 and the lid of the bushing 10
Good adhesion with 5 can be maintained. In addition, since the spiral protrusion 13 is provided above the central annular protrusion 12, even when the epoxy adhesive is filled and embedded,
It is possible to prevent air from accumulating in this part. Therefore, the cause of the filtrate can be prevented without the epoxy adhesive solidifying in the state in which the air bubbles are trapped.
