Guide apparatus

A guide apparatus comprising:

• a track rail having raceway surfaces for rolling elements formed in a longitudinal direction thereof;
• a slider which has a load raceway surface opposing the raceway surface and a return path for rolling elements disposed in parallel with the load raceway surface, said slider having a pair of reversal-of-direction paths completing an endless circulation path for rolling elements by means of connecting the load raceway surface with either end of the return path, and said slider being attached to the track rail so as to enable relative movement therebetween;
• and
• a plurality of rolling elements which are susceptible to load in a position between a load raceway surface of the slider and the raceway surface of the track rail and which circulate in the endless circulation path;
• wherein the slider comprises:
• a slide block having the load raceway surface and the return path formed therein;
• a pair of resin-made end caps being fixed to the respective ends of the slide block and each having the reversal-of-direction path formed therein;
• and
• a pair of cap attachment sections each having a semi-circular guide section which constitutes a sidewall surface at the inner diameter of the reversal-of-direction path, the cap attachment sections being formed on either end face of the slide block to be used for fixing the end caps,
• wherein the cap attachment sections are formed on the slide block by injection molding using the slide block as a core, and
• wherein a location where the guide section is connected to the load raceway surface is ground after the injection molding so that the guide section becomes continuous with the load raceway surface.
