A shrink portion (43) of the heat-shrinkable tube (41) caused to shrink by heat so as to firmly adhere to an outer surface of the fitting portion (23) is formed on a tip end side of the fitting portion (23). A non-shrink portion (45) of the heat-shrinkable tube (41) not subjected to heat shrinkage is formed on a base end side of the fitting portion (23) .
