Abstract
A support spring including a front end having a small diameter and a rear end having a large diameter. The diameter of the rear end can be varied. A cylinder block includes an annular groove, which is coaxial with the support spring. The rear end is elastically deformed in the radial direction and is positioned in the annular groove. This firmly positions the support spring and prevents vibration and noise.
