PROBLEM TO BE SOLVED: To provide a concrete mixer capable of not only effectively preventing damages due to crack, abrasion wear or the like of its constituting members, such as mixing blades and considerably prolonging its life, but also reducing adhesion of ready-mixed concrete, moreover, capable of easily performing exchange work of the constituting members on damaging. SOLUTION: The mixing blades 6a, 6b, 6c, 6d, 6e, 6f and 6g are formed from an elastomer, in the concrete mixer where a drive shaft 3 is installed in a required mixing vessel 1 so as to be able to be freely driven to rotate, and a required number of mixing blades 6a, 6b, 6c, 6d, 6e, 6f and 6g are radially mounted to the drive shaft 3 at a prescribed pitch through mounting arms 5.
