PROBLEM TO BE SOLVED: To prevent the occurrence of fretting abrasion by microscopic rocking in rolling bearings even if vibration is applied to a rotary apparatus during transportation. SOLUTION: In this rotary apparatus, a rotary body 6 is rotatably arranged to a fixed body 3, and the rolling bearings 4 and 5 making a pair in the shaft direction are arranged between the fixed body 3 and the rotary body 6. A contact seal 31 is provided on only one side end surface 29 of either one rolling bearing 5 among respective end surfaces 25, 26, 28, and 29 on the shaft directional both sides of the rolling bearings 4 and 5 making the pair. The seal is not provided or noncontact seals 27 and 30 are provided on the other end surfaces 25, 26, and 28. COPYRIGHT: (C)2003,JPO
