PROBLEM TO BE SOLVED: To provide a bearing structure of a worm gear capable of suppressing rattling of a worm gear in thrust direction, resulting in suppressed action noise. SOLUTION: The bearing structure of a worm gear includes a worm gear 10 including a worm part 11, a shaft part 12 provided to one end side of the worm part 11, and a thrust support part 13 which is formed integrally with the shaft part 12, a housing 20 where the worm gear 10 is rotatably arranged, and bearings 30 and 31 that are arranged between the worm gear 10 and the housing 20 to receive a force applied in thrust direction from the worm gear 10. The bearings 30 and 31 are arranged between the thrust support part 13 and the housing 20. COPYRIGHT: (C)2011,JPO&INPIT |
