WORKING MACHINE

Japanese Patent JP3790465

B2

PROBLEM TO BE SOLVED: To make it possible to smoothly carry out a transmission guide for a long period of time and obtain the number of engine revolutions corresponding to the operational position of a transmission lever, by stably maintaining the interlocking relationship between the transmission lever and a speed governing mechanism.
SOLUTION: The working machine is provided with the transmission lever 11 which reversely executes a forward acceleration operation and a rearward acceleration operation of a non-stage transmission for travelling, as the transmission lever 11 oscillates from a neutral position around a first shaft core to one side or the other side. A forward and rearward switching route C allowing the transmission lever 11 to move between the forward operation route and the rearward operation route is formed as the transmission lever 11 oscillates around a second shaft core being in a neutral position of the transmission lever 11. The engine speed governing mechanism is interlocked with the transmission lever 11 to be in the state of high speed revolution when the transmission lever 11 is in a high speed position. Arrangement is made so that the transmission lever 11 is made to come in contact with the guide surface 24 which slidably guides along the forward operation route by engaging the transmission lever 11 from the direction orthogonal to the guide surface 24.
