PURPOSE:To reduce a force of controlling a lever, by a method wherein a moving member is interlocked and secured to the one of an actuator for operation of a control door and a lever, a switch to the other, and the moving member and the switch are placed in a slide relation. CONSTITUTION:A control lever 21 is moved in directions B and C. This causes a microswitch 35 to slide on a moving member 36. In which case, the contact of the switch 35 is turned ON by passage of the moving member 36 through a tapered part. This forces a motor driving circuit 38 to work through a signal wire 37 to drive a motor actuator 44. The actuator 44 opens and closes a door 14 through the working of a member 45, and moves the moving member 36 in the directions B and C. When movement of the moving member 36 forces the switch 35 to drop in a taper root, the switch 35 is turned OFF, and driving of the door 14 is stopped. This reduces a force of controlling a lever. |
