The invention relates to a working machine, a bell crank (11) is connected to a boom (10) at a pivot point Y, connected to a connection link (13) at a pivot point X, and connected to a tilt cylinder at a pivot point W, and further, the tilt cylinder is connected to a structure body at a pivot point Z. A line segment L1 connects the pivot point Y and the pivot point X, a second line segment L2 connects the pivot point Y and the pivot point W, and a line segment L3 connects the pivot point W and the pivot point Z. An angle theta formed by the first line segment L1 and the second line segment L2 is equal to or less than 206.5 degrees on the bucket (20) side; an angle a formed by the line segment L2 and the line segment L3 is equal to or less than 72.3 degrees when a fork is attached; and the lower end of the bell crank (11) is positioned above the lower end of the fork when the pivot point at which the fork is connected to the boom (10) is about 1.5 m from the ground surface.
