In an excavator equipped with an offset boom, an offset command value generating means 56 of a rotation control device 50 offsets a second boom 62 arranged on a distal end side in a rotation direction relative to a first boom arranged on a proximal end side when an acceleration start judging means 53 judges that a rotation operation is started, and offsets the second boom 62 in a reverse rotation direction when a deceleration start judging means 54 judges that a rotation deceleration operation is started. Accordingly, when a rotation acceleration is performed using a reaction force generated in the offset, clearances between members of a work machine can be contracted in advance in the rotation direction, while when the rotation deceleration operation is performed, these clearances can be contracted in advance in the rotation reverse direction, thereby reducing an impact in the acceleration and deceleration.
