PURPOSE:To transfer.drive force to a rotor with a structure eliminating the need of a mechanical contact part. CONSTITUTION:Electromagnets 85 and 86 consisting of cores 85a and 86a and coils 85b and 86b are mounted to free terminals 83a and 83b of a stretching member 83 such as a magnetostriction element which stretches due to the input of a control current for stretching. A rotor 81 opposes via the electromagnet 86 and a gap. The control current for rotation is input to the electromagnets 85 and 86 in conjunction with the stretching of the free terminals 83a and 83b of the stretching member 83 to attract the rotor 81 and to rotate it without any contact. |
