WORK MACHINE, SEAL STRUCTURE FOR SHAFT, AND WORK MACHINE COMPRISING SAID SEAL STRUCTURE
A work machine (1) includes: a machine body (2); a travel device (17) that supports the machine body so that the machine body is capable of traveling; a hydraulic drive (353) that hydraulically drives the travel device; a pedal (111) for performing a braking operation of the travel device; an inching valve (338) that changes, in response to an operation of the pedal, a flow rate of a hydraulic fluid supplied to the hydraulic drive; and an adjuster (511) that adjusts a stroke of an operation of the pedal. The adjuster includes a swing member (501) that swings in coordination with an operation of the pedal and that is at a first position when the pedal is at an initial position of the stroke, a movement member (504) that is capable of performing movement in contact with the swing member and that changes the first position by performing the movement in contact with the swing member, and a switching mechanism (512) that is switchable between a first state in which the switching mechanism allows the movement of the movement member and a second state in which the switching mechanism prohibits the movement of the movement member.
