<p>PURPOSE:To increase the workability in combining its elastic and rigid portions together and also confirm their combined state, by providing a recessed part on the outer peripheral side of the elastic portion, and providing a projecting part capable of being fitted into the recessed part of the elastic portion on the inner peripheral side of the rigid portion. CONSTITUTION:A bundle 31 of wires is inserted into the fixing portion 33 of its elastic portion 23; the reduced diameter part of the fixing portion 33 expands during the insertion so that the elastic portion 23 is fixed at near the reduced diameter part to the bundle 31 of wires. Next, two half-sized bodies of the rigid portion 25 are combined together while being caused to move toward each other, and the projecting part 51 of the rigid portion 25 is fitted into the recessed part 41 of the elastic portion 23 simultaneously; the elastic portion 23 and the rigid portion 25 are thus combined together. This combining work is extremely simple because it can be accomplished only by fitting the rigid portion 25 into the elastic portion 23 from the external of the latter. Also, the elastic portion being pressed at its outer peripheral side by the rigid portion, their combined state is extremely stable.</p> |
