PROBLEM TO BE SOLVED: To provide a platform of a wheel type working vehicle allowing easy mounting/removing of a tire. SOLUTION: This platform is provided with a cut-out part provided to direct an open part to the outside within a range for projecting wheels upward and a cover for covering the cut-out part. A longitudinal direction dimension W1 of the cut-out part and a diameter D1 of a rear wheel satisfy a relation of 0.25×D1≤W1≤0.35×D1. A distance W2 from a left and right direction center line of the rear wheel up to an inside end part of the cut-out part and a dimension D2 to be half of the width of the rear wheel satisfy a relation of 0.2×D2≤W2≤0.6×D2.
