Provided is a mixer vehicle capable of preventing ready-mixed concrete from spilling out from an opening of a mixer drum when driving up an ascending slope. A vehicle body (10) includes a mount (13). A mixer drum (20) has an opening (27) that opens to the rear end, and is rotatably mounted on the mount (13) in a forward-tilted orientation. The mixer drum (20) includes a helical drum blade (25) fixed to the inner wall surface thereof, and when the mixer drum (20) is subjected to positive rotation, ready-mixed concrete introduced therein is moved forward by the drum blade (25). A rotating device (40) causes the mixer drum (20) to rotate. An angle acquisition device (50) acquires the inclination angle of the mount (13) in the front-to-rear direction. When the inclination angle acquired by the angle acquisition device (50) becomes greater than or equal to a predetermined angle in a state where the mount (13) is in a downwardly inclined state from the front end toward the rear, a control device (70) executes a sloping road control by which the rotating device (40) increases the rotation speed of the positive rotation of the mixer drum (20).
