ーリング用油圧構造。[Claims for Utility Model Registration] 1. Pressure from one of the actuators 5 is transmitted to the branch portion 22 which separates pressure oil from the single pressure oil supply path 15 to the left and right working device rolling actuators 5a, 5b. Due to the pressure difference in a state that is greater than the pressure from the other actuator 5,
A work in which a valve body 23 is provided that blocks the oil passage 16 to the other side and the pressure oil supply passage 15 and at the same time connects the oil passage 16 to the one actuator 5 and the pressure oil supply passage 15. Hydraulic structure for machine rolling. 2. The actuators 5a and 5b each consist of a lift cylinder provided on the left and right sides of the aircraft body, and
The hydraulic structure for rolling of a work machine according to claim 1, wherein the valve body 23 is formed into a spherical shape. 3. The hydraulic structure for rolling of a working machine according to claim 1, wherein the valve body 23 is configured to swing due to the pressure difference between the two oil passages 16, 16.
