The upper case member has a piston rod disposed therethrough. The lower case member, disposed under the upper case member, has the piston rod disposed therethrough. The center plate, disposed between the upper and lower case members such that the piston rod passes through the center plate, is configured to induce either one or both of the upper and lower case members to rotate. The lubricant storage part is formed in the center plate and configured to store lubricant therein. Each of the upper case member, the lower case member, and the center plate is composed of a synthetic resin material.
