Driven equipment for fluid machinery, having a small-sized, light weight, simple structure and capable of carrying out suction and exhaust operations with a high efficiency, comprising a rotary means; wherein a rotary body (3) provided with crosswise extending arms (5a, 5b) on a boss (4), and a rotary member (7) provided on rear sides of both end portions thereof with inwardly curved slide surfaces (7b) formed around a pin hole (6a) of a support portion (6) as a fulcrum; and a sliding member (8) provided with a pin receiver (10) at a central portion of a plate type sliding member body (9) having a gently convex outer surface (9a), sliding sections (11) having sliding surfaces (11a) on the outer sides thereof and formed symmetrically at both ends of the sliding member body (9), which extends at right angles to the pin receiver (10), with the sliding surfaces (11a) facing in the outward direction, and a seal (15) provided rockingly in a surface which the outer surface (9a) and sliding surface (11a) intersect are joined to eachother by pin (14); a cylindrical driven rotary means, an inner circumferential surface of which is formed to an arbitrary curved cross-sectional shape, being combined with the rotary means in such a manner that rotary means is rotated in the driven rotary means.
