ABSTRACT:
The invention is directed to improvements to the assembly of a unitized spring device. The spring device comprises a pair of retainer members which are tubular in shape and hollow inside. The retainer members have different outer circumference diameters which allow the second retainer member to fit onto the outer circumference of the first retainer member. The first retainer member has a first outward claw portion at one end and the second retainer member has a second inward claw portion at one end, such that the second claw portion can move beyond the first claw portion to couple the first and second retainer members in the axial direction. These first and second claw portions prevent one another from being pulled out in the coupled state. The first retainer member also comprises a slit which extends in the axial direction and divides at least the side having the first claw portion.
