<P>PROBLEM TO BE SOLVED: To provide an elastic upright body which can attach an outer support to an inner support with high strength, and facilitates forming work thereof. <P>SOLUTION: In formation of the elastic upright body, when a spacer 3 which has an internal diameter W1 smaller than an external diameter W2 of a support body 21, is mounted on the support body 21 by expanding a notched portion 31 by using the flexibility of a synthetic resin material of the spacer, an area near the notched portion 31 undergoes deflection expanding outward. The outer support 1 is made of a flexible synthetic resin, and fitted on the spacer 3 inclusive of the area near the notched portion 31, to thereby form the upright body through simple work. Herein, due to the deflection of the spacer 3 in the horizontal direction, in the area near the notched portion 31, energizing force is generated from the spacer 3 outward, and therefore, the outer support 1 is resistant to slipping out of the spacer, which leads to mounting of the outer support 1 on the inner support 2 with high strength. <P>COPYRIGHT: (C)2009,JPO&INPIT |
