<p>PURPOSE:To prevent the damage of an oil supply hose at the connecting part and expand the oil supply range, by connecting the flow in pipe and flow out pipe in such a manner to be free to give a planar turning, connecting the flow in pipe to an oil supply pipe in such a manner to be free to give a linear turning and connecting the flow out pipe to a hose in such a manner to be free to give a linear turning. CONSTITUTION:An oil supply pipe 3 and flow in pipe 8 constitute a swivel joint 10 which gives a linear turning. In the meantime, to an attaching pipe 14 which is fixed on the end part of an oil supply hose 5, a flow out pipe 12 is attached to be free to give a linear turning, sealed by an O-ring 19 and prohibited from slipping out by a ball 20. As a result, the flow in pipe 8 and the flow out pipe 12 are connected to be free to give a planar turning. That is, to the flow in pipe 8, a swivel pipe 11 is screwed in, at a right angle to the axial center of the oil supply pipe 3. On the flow out pipe 12, a fitting part 12Y in which the swivel pipe 11 is fitted is formed at a right angle to the axial center of the attaching pipe 14, and the swivel pipe 11 is fitted in. As a result, a swivel joint 13 for which the flow in pipe 8 and flow out pipe 12 give a planar turning is constituted.</p> |
