PURPOSE:To enhance durability with a small size by supporting an annular contact member to a main shaft holding member through a flexible member, and sequentially expanding and contracting an expanding/contracting member. CONSTITUTION:A motor is composed of a main shaft 1, a casing 3 of a holding member, a hollow transmission member 5 made of a base 6, a flexible part 7 and a flange 8 of a contact member, expanding/contracting members 9A-9C, etc. When the members 9A-9C are sequentially expanded and contracted at each predetermined period around the shaft 1, the member 8 rotates around the shaft 1 in contact therewith, and the shaft 1 is rotated. |
