摘要： A linkage mechanism of a work implement installed in a loading vehicle such as a shovel-loader or the like, which is adapted to vertically move a bucket as held in a horizontal state without operating tilt-cylinder, while preserving the function of the Z-bar linkage in the prior art; in which linkage mechanism, when the distance from a pivotable support point (A) between a bucket (3) and a lift arm (1) to a pivotable support point (B) between the lift arm (1) and a bellcrank (5) is represented by (X) and the distance from the above-mentioned pivotable support point (B) to a pivotable support point (O) between the lift arm (1) and a vehicle body (9) is represented by (Y), they are preset so as to fulfil Y/X=.alpha., and also, first and second triangles (.DELTA.ABC, .DELTA.OBE) formed by the liftarm (1) and the bellcrank (5) on the vehicle body side and on the bucket side, as well as a third triangle (.DELTA.ADC) formed by a tilt rod (6) and the bucket (3) and a fourth triangle (.DELTA.OFE) formed by a tilt cylinder and the vehicle body (9) are preset so as to respectively fulfil a mutually similar figure relation.

摘要： A circle structure of a motor grader excellent in durability at low maintenance cost. For this purpose, the circle structure includes a drawbar (105), at least one guide shoe (213) attached to the drawbar, an integrated ring-shaped circle gear (211) rotatably supported by the guide shoe, a plurality of circle gear mounting bolts (215) placed at equal pitches on a mounting pitch circle of the circle gear, and a circle (104) which is mounted to the circle gear by the circle gear mounting bolts and rotatable with respect to the drawbar.
