Abstract

PURPOSE: To suppress raising of the center of gravity of a vehicle body, by constructing it in a tripple structure which results in shortening a rotary joint.
CONSTITUTION: A rotary joint 8, which is located between a running chassis 2 and a fluid pressure feeder 7 being mounted on a ratoary stand 3, shall be constructed in a tripple structure being composed of a core 12, a No.1 cylinder 10 and a No.2 cylinder 11. And thus, a connecting passage R, which is always linked together, is formed with ring grooves 13 made in the core 12 and the NO.1 cylinder 10, a pressured oil passage R1 made in the No.2 cylinder 11, and a pressure oil passage R2 made in the NO.1 cylinder 10. Thus a fluid pressure is supplied to a hydraulic cylinder 9 and a running motors M1 and M2 from the fluid pressure feeder 7 irrespective of the attitude of the rotary stand 3 against the running chassis 2. Besides, since many passages can be connected together without lengthening the length of the rotary joint 8, the center of gravity of the vehicle body can be suppressed from being raised.
