An electric travelling vehicle including: a motor controller (61) configured to control an electric motor (20) based on displacement of a steering operation part (15) to a forward travel position, a neutral position, and a rearward travel position, a brake controller (62) configured to bring an electromagnetic power-off brake (5) into a released state or a braking state; and a travel state detector (63) configured to detect a travelling state that is accompanied with the released state, a stopped state that is accompanied with the braking state, and a transit stopped state that is accompanied with the braking state. In the travelling state, the steering operation part (15) has deviated from the neutral position, the electromagnetic brake is in the released state, and the electric motor (20) is in an excited state. In the transit stopped state, the steering operation part (15) is at the neutral position, the electromagnetic brake is in the braking state, and the electric motor (20) is in an unexcited state. A transition to the transit stopped state occurs on a condition that, in the travelling state, the steering operation part (15) has been returned to the neutral position and a predetermined period of time has elapsed upon a rotational speed of the electric motor (20) decreasing to a very low rotational speed.
