Document Type and Number:
Japanese Patent JP2015200195
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To enable a reliable and stable choke operation to be carried out by a relative simple configuration, in a work machine for changing-over a stop operation, a driving operation, and a choke operation of an internal combustion engine.SOLUTION: An operation lever 11 and a rotating member 12 rotatably assembled with the operation lever 11 are held in a state in which they are abutted to each other by a twisted coil spring 13 at a chain saw. The rotating member 12 is connected to a choke operating member 22 through a choke rod 31 so as to be restricted against a turning from a driving position P1 toward a stop position P2. Then, when the operation lever 11 is turned from the operating position P1 to the choke position P3, the rotating member 12 is also turned to move the choke rod 31, thereby the choke operating member 22 closes the choke valve. In turn, the rotating operation of the operation lever 11 from the operating position P1 to the stop position P2 is carried out against the rotating force of the twisted coil spring 13.
