Claims

[Scope of utility model registration request]

A recessed portion for storing spiral splashes is formed at one end of the drum, and a first recessed portion facing substantially the same direction as the central axis of the drum and communicating with the recessed portion is formed from one end and the other end of the drum on the outer periphery of the recessed portion. By drilling a bottomed hole and a second bottomed hole that faces substantially the same direction as the central axis of the drum and whose inner side communicates with the first bottomed hole in a staggered manner, Bent in a hook shape outward from the periphery of the recess;
and a retaining hole having a bag-like tip, and a U at the outer end of the spiral spring accommodated in the recess is provided in the engaging hole.
A structure of a spiral spring locking part in a drum, characterized in that it can lock a letter-shaped bent part.
