Claims

[Scope of utility model registration request]

A drive shaft 19 that decelerates the rotation of the electric motor 2 and rotates in forward and reverse directions has one end pivoted to a frame and the other end equipped with a reduction gear 6, and one end pivoted to yokes 26 and 26' fixed to the frame 16. The other end of the drive shaft 19 is pivotally supported, and the free end faces the yokes 26, 26' so as to be able to come into contact with and separate from them, and the free end is spaced apart from the yokes 26, 26'. An iron piece 15 is biased by a spring 17 and driven to swing around the one end so that the free end is attracted to the yoke by the bias of the solenoid coil 14, and the output shaft 7 is connected to the throttle valve. In the clutch mechanism of an automatic constant speed traveling device, the clutch mechanism includes a driven gear 8 which is fixed and is within the swing range of the reduction gear 6 and is disposed so as to be able to mesh with the reduction gear 6 when the solenoid coil is energized. A protruding member 28 or 30 made of a non-magnetic material is fixed to one end of the facing portion of the free end of the iron piece 15 or one of the yokes 26, 26' that the free end faces to define the gap when both are attracted. A clutch mechanism for an automatic constant speed traveling device, characterized in that the position of the spring 17 is set so that the biasing stress of the spring 17 acts on the other end A of the facing portion of the iron piece.
