<p>The invention is directed to improvements to the assemblability of a unitized spring device (51) itself. To this end, the invention is characterized in the following features A, B, and C. A. Each of the pair of retainer members (60, 70) is tubular in shape and hollow inside, and on the outer circumference of a first retainer member (60) having a smaller diameter, a second retainer member (70) having a larger diameter is fitted.- B. The first retainer member (60) has a first outward claw portion (610) at one end, the second retainer member (70) has a second inward claw portion (720) at one end, the second claw portion (720) can move beyond the first claw portion (610) to couple the first and second retainer members (60, 70) in the axial direction, and these first and second claw portions (610) and (720) function to prevent one another from being pulled out in the coupled state. C. The first retainer member (60) comprises a slit (602) extending in the axial direction and dividing at least the side having the first claw portion (610).</p> |
