PROBLEM TO BE SOLVED: To attain functionability and function certainly irrespective of tolerance and measurement difference by additionally arranging an elasticity or a member having elasticity which can be previously regulated, on a transmitting passage between a driving device and a changeover means. SOLUTION: An elasticity or an elastic member 211 is additionally arranged between a driving device 212 and a changeover means 209 inside a transmission for transmitting force or supporting force. When operation members 210a, 210b are introduced over a position corresponding to a terminal position of the changeover means inside the transmission to their terminal position, high load is applied to a component of the transmission or a component of an operation factor 202. The high load is eliminated or attenuated by the elastic member 211 when the changeover means 209 exists at the terminal position and the operation members 210a, 210b are successively introduced to their terminal position. |
