In this boom slewing angle detection device, a slewing angle detecting gear is attached to an end of a shaft of a pinion gear that meshes with a ring gear formed on a slewing bearing rotatably supporting a crane boom, and the amount of rotation of the slewing angle detecting gear is detected by a slewing-angle-detecting proximity sensor. The slewing angle detecting gear is not meshed with the ring gear or the pinion gear, which compose a slewing force transmission mechanism; thus, grease, and the like, do not adhere to the slewing angle detecting gear, and external teeth for detection of the slewing angle detecting gear are not subject to wear, so accurate slewing angle detection is possible.
