The overhanging storage mechanism for a jib is provided with: a guide roller (31) and a pin socket (45) that are provided to a jib (15); and a guide (32) and a jib-fixing pin (43) that are provided to a base end boom (14a). The guide (32) comprises a first raceway surface (34s) that pulls the jib (15) toward the bottom surface of the base end boom (14a) as a result of rolling of the guide roller (31), a second raceway surface (35s) on which the jib (15) moves along the base end boom (14a), and a protruding third raceway surface (36s) that protrudes from the second raceway surface (35s). The jib (15) is pulled further toward the bottom surface of the base end boom (14a) by rolling of the guide roller (31) on the third raceway surface (36s).
