Claims

[Scope of utility model registration request]

(1) A plunger with a bottomed hole is inserted into a plunger chamber with one end open and the other end closed, and the plunger is slidable in the axial direction but not rotatable around the shaft. A tensioner in which a coil spring is loaded in a compressed state between the bottom of the bottom hole and the plunger is urged to pop out from the plunger chamber,
A bolt insertion hole having an inner diameter smaller than the inner diameter of the coil spring is provided through the closed end of the plunger chamber, and a spring holder that pinches the coil spring between one end of the bolt inserted into the coil spring and the closed end of the plunger chamber. An assembly device for a protruding biased plunger, which is provided with a spring socket hook member for displacing the spring socket between a coil spring compressed state and a released state at the other end inserted and projected from the bolt insertion hole.

(2) An assembly device for a protruding biased plunger according to claim 1, in which the spring socket member is a nut screwed onto a bolt.

(3) An assembly device for a protruding biased plunger according to claim 1, in which the spring socket hook member is a stopper that is engaged with a bolt.

(4) An assembly device for a protruding biased plunger as set forth in claim 1 of the utility model registration claim, in which the spring receiver is screwed onto a bolt and then formed into a nut.
