Claims

[Scope of utility model registration request]

A switching lever that can be operated to switch between a running position and a parking position and a working lever that operates an actuator of a working device are provided in the driver's cab, and when the switching lever is switched to the parking position, even if the working lever is operated, In a working machine in which the actuator is prevented from malfunctioning, the area near the entrance of the operator's cab can be moved between an obstruction position that is an obstruction to getting in and out of the operator's cab and a non-obstruction position that is not an obstruction to getting in and out. a moving lever, and an interlocking mechanism that moves the switching lever to a fault position when the switching lever is set to a running position, and switches the switching lever to a parking position when the moving lever is moved to a non-faulting position. A work machine characterized by:
