Abstract
Each of end caps attached to opposite ends of a slider main body has a curved ball groove for connecting a ball rolling path formed by mutually opposing ball rolling grooves of a guide rail and a slider main body to a ball circulating path of the slider main body. In the end cap, the end portion of the curved ball groove to be joined to the ball circulating path of the slider main body is extended tangentially toward the slider main body to form a fitting protrusion having an extended groove. The slider main body is formed with a fitting recess in the end face thereof at the end portion of the ball circulating path to receive the fitting protrusion therein. When the fitting protrusion is fitted into the fitting recess, the curved ball groove is connected to the ball circulating path through the extended groove of the fitting protrusion without causing a stepped portion to be formed at the joining portion between the end cap and the slider main body.
