<P>PROBLEM TO BE SOLVED: To prevent an emergency stop button from being easily pressed by an operator, by making a lock state difficult to be unlocked when the emergency stop button is pressed. <P>SOLUTION: An emergency stop button switch 1 is held in a pressed state by a lock mechanism when a switch pressing part 11 is pressed, and is unlocked by turning the switch pressing part 11 in a circumferential direction. A control panel 2 has a through hole 5 having a size of a fingertip, and is detachably fixed to an outer surface of an engine-driven working machine by fasteners such as screws. A switch bracket 3 having openings 6 in side parts is attached on the inside of a part where the through hole 5 of the control panel 2 is formed, and the emergency stop button switch 1 is attached to the same. Thereby, when the emergency stop button switch 1 is pressed, the lock cannot be unlocked unless the control panel 2 is detached by removing the fastener with a tool. <P>COPYRIGHT: (C)2013,JPO&INPIT |
