are protruding in a fork shape, and locking claws 33, 3 are provided on both legs 32, 32, respectively, and thrust into the side surface of the rod-shaped body 2.
3 are formed facing each other. Locking member 3
is preferably formed integrally by bending a single wire (preferably a spring steel wire).
係止部材３の基部３１（索体４の取付部）には
引き出し用の索体４の一端４１を連結している。
索体４には、ワイヤーや紐等が用いられる。 One end 41 of a pull-out cable 4 is connected to the base 31 of the locking member 3 (the attachment part of the cable 4).
A wire, a string, or the like is used for the cable body 4.

じか、やや小さく形成している。 The holding member 5 used is, for example, a coil spring wound into a substantially bell shape, into which the locking member 3 described above can be fitted. Then, the cable body 4 is inserted into the narrow neck part 52 with the wide opening 51 facing outward. Therefore, the holding member 5 is prevented from coming off the cable body 4. Since the holding member 5 is formed in this way, the lower end 22 of the rod-shaped body 2 with the locking member 3 locked thereon can be elastically held by the holding member 5.
The locking member 3 can be held so that it does not easily fall off the rod-shaped body 2. Moreover, this holding member 5
also serves to protect the lower end 22 of the rod-shaped body 2 from being destroyed during insertion. The inner diameter of the holding member 5 is the same as or slightly smaller than the outer diameter of the rod-shaped body 2.
保持部材５として、他にゴム材製等の袋体を用
