Claims

[Scope of utility model registration request]

A pair of raised pieces are vertically protruded from the upper surface of the annular substrate at regular intervals, and a locking piece is cut diagonally downward at the middle part of each of the pair of raised pieces to secure the lower end of the coil spring. The locking piece is pressed from above along the outside or inside of the pair of cut-and-raised pieces to one side of the cut-and-raised pieces, and then the locking piece is returned to its original position by its own elasticity to lock the lower end of the coil spring. A spring assembly that abuts and locks on the inner surface of the stop piece.
