ABSTRACT:
A rotary joint comprises: a joint main body constructed of a casing (1) and a housing (3); and, a rotary body (8) inserted in the joint main body and rotatably mounted therein. In the joint: a part of an outer peripheral surface of the rotary body (8) serves as a corresponding inner race of a sliding bearing; and, the sliding bearing rotatably supports the rotary body (8), and constructed of the corresponding inner race (11) and a corresponding outer race (10) incorporated in the housing (3). The sliding bearing (10, 11) may be constructed of: a plurality of units of thin-width sliding bearings; or, a single unit of a thick-width sliding bearing. A pin (12) is pounded into the joint and engaged with both the outer race (10) and the housing (3), whereby the outer race (10) is prevented from rotating in operation.
