摘要

PROBLEM TO BE SOLVED: To reduce the number of parts of a cam mechanism and to simplify a structure in an operation lever apparatus which is equipped with a throttle lever and a lock lever and locks the throttle lever by the lock lever through a cam by a pressing and energizing means. SOLUTION: In a working machine equipped with an operation instrument to be driven by a motor and with an operation handle having an operation part to control the motor, the operation part attached to the operation handle is provided with a throttle lever 30 and a lock lever 40 for controlling the operation position of the throttle lever 30 through a pressurizing mechanism 50. The pressurizing mechanism 50 consists of a first cam 23 formed integrally with the machine body of the operation handle coaxially on a spindle 61 of the lock lever 40, a second cam 47 attached to the lock lever engaged with the first cam 23 and a pressurizing and energizing means 52 arranged at the side of a face opposite to the second cam 47.
