The step is configured from: a receiving part which engages with a foot of an operator; a front support part for supporting a front of the receiving part; and a rear support part for supporting a rear of the receiving part. One end of the front support part is coupled to a cabin frame. Another end of the front support part is coupled to a tractor side end surface of the receiving part. One end of the rear support part is coupled to a front-side end part of a fender of the rear wheel. Another end of the rear support part is coupled to a rear-side end surface of the receiving part.
