PROBLEM TO BE SOLVED: To compactly and inexpensively constitute a lift drive mechanism of an attachment with a small number of components, sufficiently assure a turning angle of the attachment and bring the attachment to be compactly housed. SOLUTION: A working implement 1 is equipped with a working implement body 2 connected to a travelling machine body 100 and performing a predetermined work, and the attachment 3 connected to the main body 2 movably upward/downward, and operated to move upward and downward depending on states of work. In the working implement 1, supporting plates 26, 27 integrally connected to the attachment 3 are supported to be rotative upward and downward on the side of the working implement body 2, a pinion gear 28 is geared to gear teeth 26a formed on the peripheral part of the support plate 26, and the attachment 3 is lifted by rotatively driving the pinion gear 28.
