An apparatus for moving a counterweight includes an attachment fixed to a frame of a machine, a supporting member that includes a supporting face for placing a counterweight thereon when the counterweight is mounted on the machine, and a link mechanism that moves the counterweight. The link mechanism includes an arm and a rotating cylinder that rotates the arm. One end of the arm is pivotally supported by the attachment while the other end of the arm is pivotally supported by the upper inner portion of a recess of the counterweight. One end of the rotating cylinder is pivotally supported by the upper inner portion of the recess of the counterweight. The supporting face is shaped so as to coincide with the arc locus drawn by a contact face arranged on the side of the counterweight, as the counterweight moves. The contact face comes into contact with the supporting face when the counterweight is mounted on the machine. The apparatus has a simple structure that avoids interference between the counterweight and supporting member when the counterweight is moved.
