摘要： This invention relates to an operation machine link mechanism which keeps a conventional Z bar linkage function, moves up and down a bucket under a horizontal state without operating a tilt cylinder and is mounted to a loading vehicle such as a loader shovel. When a distance from a pivotal point (A) between a bucket (3) and a lift arm (1) to a pivotal point (B) between a lift arm (1) and a bell crank (5) is (X) and a distance from the pivotal point (B) to a pivotal point (0) between the lift arm (1) and a car body (9) is (Y), the link mechanism is set to Y/X = a and first and second triangles (AABC, AOBE) defined by the lift arm (1) and the bell crank (5) on the car body side and on the bucket side, respectively, have mutually similar relationship with a third triangle (AADC) defined by a tilt rod (6) and the bucket (3) and a fourth triangle (AOFE) defined by the tilt cylinder and the car body (9).
