Kind Code:

A1

Abstract:

Brake mechanisms(33) for braking the rotation of left and right rotating shafts (25) are each configured to comprise: a protrusion portion (40) facing a partition wall (15A) of a brake case (15) and protruding radially inward from the inner diameter side of a piston (37); an engagement member (41) disposed on the inner diameter side of the piston (37) while being engaged with the protrusion portion (40) so as to be movable a predetermined distance in the left-right direction; and a pin member (42) disposed between the engagement member (41) and the partition wall (15A) of the brake case (15). The frictional resistance force between the pin member (42) and the partition wall (15A) is set to a value smaller than that of the pressing force of the piston (37) during braking. The protrusion portion (40) is provided with an engagement member insertion groove (40A) through which the pin member (42) extends in the left-right direction. The engagement member (41) is engaged with the protrusion portion (40) so as to be movable in the left-right direction.
