PROBLEM TO BE SOLVED: To provide a swivel joint capable of reducing an axial dimension.SOLUTION: At a cylinder part 34 of a body 32, a cylinder part hydraulic oil passage 35 is provided. At a spindle 53, a cylinder opening hydraulic oil passage 58 communicating with the cylinder part hydraulic oil passage 35 is provided. At a bottom surface 45 of a bottom part 44 of the body 32, an annular projection part 46 projecting toward the spindle 53 is provided. At a lower end surface 53B of the spindle 53, an annular recessed part 61 into which the projection part 46 is inserted is provided. At the bottom part 44 of the body 32, a body side fuel supply passage 50 is provided in which one side opens to a lower surface 48 and the other side opens to an apex of the projection part 46. At the spindle 53, a spindle side fuel supply passage 63 is provided in which one side opens to the bottom part of the recessed part 61 and the other side opens to an upper end surface 53A of the spindle 53. Also, at the bottom part 44 of the body 32, a mixture recovery passage 52 is provided in which one side opens to the lower surface 48 and the other side opens to both an outer peripheral surface and an inner peripheral surface of the projection part 46.SELECTED DRAWING: Figure 3
【課題】軸方向寸法を低減できるスイベルジョイントを提供する。【解決手段】ボディ３２の筒部３４には、筒部作動油通路３５を設ける。スピンドル５３には、筒部作動油通路３５と連通する筒開口作動油通路５８を設ける。ボディ３２の底部４４の底面４５には、スピンドル５３に向けて突出する円環状の突出部４６を設ける。スピンドル５３の下端面５３Ｂには、突出部４６が挿入される円環状の凹陥部６１を設ける。ボディ３２の底部４４には、一側が下面４８に開口し、他側が突出部４６の頂部に開口するボディ側燃料供給通路５０を設ける。スピンドル５３には、一側が凹陥部６１の底部に開口し、他側がスピンドル５３の上端面５３Ａに開口するスピンドル側燃料供給通路６３を設ける。さらに、ボディ３２の底部４４には、一側が下面４８に開口し、他側が突出部４３の外周面と内周面との両方に開口する混合液回収通路５２を設ける。【選択図】図３
