The invention provides a cloth position adjusting device of a sewing machine, and belongs to the technical field of sewing machines. The cloth position adjusting device solves the problems that as for an existing sewing machine, cloth is deviated from a set path, and working quality is influenced. The sewing machine comprises a cloth feeding table, and a backup plate is fixedly connected to the upper lateral side of the cloth feeding table and comprises a guiding edge. The cloth position adjusting device comprises a friction wheel and a swinging base. A sensor capable of detecting deviating of the cloth position is arranged on the cloth feeding table. One end of the swinging base is hinged to the cloth feeding table. The friction wheel is hinged to the other end of the swinging base. A driving piece capable of driving the swinging base to swing downwards is arranged on the cloth feeding table. A power source capable of driving the friction wheel to rotate is further arranged on the cloth feeding table. By means of the cloth position adjusting device of the sewing machine, when deviated in the movement process, the cloth can return to the set path.
