To make it possible to make a ratchet mechanism a lock state and to prevent towed matters from backing even though an electric system of an electromagnetic clutch breaks down.
An electric winch has an electromagnetic clutch 84 making a drum and a motor section 81 a fastening state by energization and making the drum and the motor section 81 an opening state by releasing the energization, and a ratchet mechanism which becomes a release state by the energization of the solenoid driving member 93c and allows rotation of the drum in one direction and in another direction and which becomes the lock state by the release of the energization of the solenoid driving member 93c and allows rotation of the drum in the one direction while regulating the rotation of the drum in the other direction, each of power source terminals T1 of the electromagnetic clutch 84 and the solenoid driving member 93c is electrically connected to the other end side of one power source feeding line 53 whose one end is connected to a power source 51 via a branching point V1.
