<P>PROBLEM TO BE SOLVED: To provide an implement attaching device for a working vehicle including a three-point link mechanism capable of adjustment without component replacement. <P>SOLUTION: The implement attaching device includes: lift arms 13 and 13 axially supported to a machine body; lift links 14L and 14R axially supported to the lift arms 13 and 13; and lower links 16 and 16 axially supported to the machine body. The lower link 16 includes the three-point link mechanism, in which height adjusting attaching holes 30, 31 and 32 are formed at positions on height adjusting arcs R1 and R2 separated from intersections P1 and P2 between the height adjusting arcs R1 and R2 around a lower link axis 16a and a reference arc R0 around a lift link axis 14a by optionally selected circumferential lengths L1 and L2 for respective height adjusting arcs R1 and R2 whose diameters are differently set, and in which the other side of the lift link 14L or 14R is connected to one height adjusting attaching hole 31 of the height adjusting attaching holes 30, 31 and 32. <P>COPYRIGHT: (C)2012,JPO&INPIT |
