A first width direction bending portion bendably connects a portion of a guy link on a distal end side with respect to a first link portion to the first link portion in a width direction. When the guy link is in a stored state, the portion of the guy link located on the distal end side with respect to the first width direction bending portion is disposed outside the first link portion in the width direction. When the guy link is in a stored state, at least a portion of the guy link is disposed on the outer side in the width direction than a front strut and on a back surface or a side surface of a lower jib.
