PROBLEM TO BE SOLVED: To provide a slider structure for a robot actuator, having a reduced weight and improved rigidity for preventing the leakage of lubricating oil to the outside. SOLUTION: A slider 5 consists of a slider body 17 to be reciprocatingly operated by a drive mechanism, a sliding member 16 mounted on the slider body 17 and having sliding portions on the front and rear parts and the intermediate part in the moving direction for sliding on a band sheet 10, and a cover member mounted on the upper face of the sliding member while covering the sliding member. The sliding member consists of a pair of mutually opposed roller holders 19, elastic rollers 23 mounted on shafts 20<SB>1</SB>, 20<SB>2</SB>provided at the longitudinal ends of the roller holders 19 between the roller holders 19, and the sliding portions provided at the intermediate parts of the roller holders 19 and supported between the roller holders 19. The band sheet 10 is arranged passing through the upper faces of the sliding portions 21 at the intermediate parts of the roller holders 19 and through the lower faces of the front and rear elastic rollers 23.
