Abstract
A work machine capable of decreasing the height of a work attachment in a folded state and suppressing the influence on the operability during demolishing operation. An arm has a surface facing downward when the attachment is in a folded posture, and the surface includes a flat arm contact surface capable of making contact with a mounting surface, on which a work attachment is mounted; and an attachment surface that extends in the direction away from the mounting surface. A work device cylinder is attached to the attachment surface so as not to make contact with the mounting surface. When the attachment is in the attachment folded posture, the arm contact surface is more parallel to a boom upper surface than a boom-side sloped surface and an arm-side sloped surface or is parallel to the boom upper surface.
