PROBLEM TO BE SOLVED: To provide a rolling guide apparatus capable of using either of grease and oil as a lubricant.SOLUTION: A rolling guide apparatus includes a plurality of rolling bodies, a raceway member having a rolling body rolling plane where the rolling bodies roll, and a moving member which is incorporated in the raceway member through the rolling bodies and can move along the raceway member. The moving body includes a moving member body which has a load passage where the rolling bodies roll while placing a load and a rolling body return passage parallel with the load passage, and a pair of cover members which are fixed to both movement-directional ends of the moving member main body, and connects the load passage and rolling body return passage to each other to form a direction change path constituting an endless circulation path for rolling body. The cover members each includes a lubricant introduction path into which a lubricant is injected, a guide flow passage guiding grease to the direction change path, an intermediate flow path connecting the lubricant supply hole and guide flow passage to each other to form a lubricant supply path, and a coating body which has one end brought into contact with a surface of the raceway member while facing the intermediate flow path, and has a plurality of gaps impregnated with the oil. |
