An object suction device that more effectively sucks an object includes a pipe, a rotating member that is rotatably provided in the pipe and conveys an object that enters from an opening portion provided at a distal end of the pipe toward a rear end of the pipe, an air motor that rotates the rotating member, a nozzle that sucks the object discharged from the rear end of the pipe, and a channel that is connected to both the nozzle and the air motor and forms a flow of air and the object.
