PROBLEM TO BE SOLVED: To provide a seat turning device which is less in physical load and hardly realizes improver operation. SOLUTION: Gears 42-45 are supported by bearings 38-41 erected on a base 11 to turnably support a substrate 13. The gears 42, 43 are turnable only in the directions of arrows R1, R2. The gears 44, 45 are non-turnable. Tooth forming bodies 36, 37 are fixed to a rotary shaft part 292 of a lever 29. The gears 42, 44 are provided immediately below the rotational locus of the tooth forming body 36 when the substrate 13 is turned around a shaft 14. The gears 43, 45 are provided immediately below the rotational locus of the tooth forming body 36 when the substrate 13 is turned around the shaft 14. A plurality of first driving teeth 361 are integrated with a circumferential surface of the tooth forming body 36. A plurality of second driving teeth 371 are integrated with a circumferential surface of the tooth forming body 37. The first driving teeth 361 are engaged with the gears 42, 44, and the second driving teeth 371 are engaged with the gears 43, 45. COPYRIGHT: (C)2006,JPO&NCIPI
