る。FIG. 1 is a perspective view of a skeleton member, and FIGS. 2 and 3 are cross-sectional views of a seal member. The skeletal member 1 includes a front cylindrical portion 2, a central bridge portion 3, and a rear flange portion 4 and is molded from a rigid material such as a synthetic resin.
Has a substantially elliptical cross section. And the cylindrical part 2
The flange portion 4 is connected by a plurality of bridging portions 3 having elasticity and bulging outward. A sealing member 5 made of elastic synthetic rubber or the like is attached to both the inner and outer surfaces of the cylindrical portion 2 and the bridging portion 3 in a substantially cylindrical shape. The sealing material 5 is integrally molded in a bag shape at the tip of the cylindrical portion 2, and a plurality of corrugated sections 6 are formed on the inner and outer surfaces of the sealing material 5 covering the bridging portion 3 so as to sufficiently exert a sealing function. Have been.
