Abstract:
A pedal operation switching mechanism (24) can switch a foot pedal (22) to one of three movement patterns: a front and rear step pattern that allows the front side of the foot pedal (22) to be pressed from the neutral position of a pivoting part (19) of a pilot valve (17) and the rear side of the foot pedal (22) to be pressed from the neutral position of the pivoting part (19); a front step restricted pattern that only allows the front side of the foot pedal (22) to be pressed from the neutral position of the pivoting part (19); and a fixed pattern that fixes movement of the foot pedal (22) to the neutral position of the pivoting part (19).
