摘要： A fixing device of a motor of an air compressor contains: a body, a cylinder, a motor, a transmission mechanism, and at least one retainer. The body includes a first positioning orifice and a second positioning orifice. The cylinder is connected on the body. The motor is fixed on the body, a small gear is received in the first positioning orifice and is connected on the motor, and a connection seat of the motor is accommodated in the first orifice. The transmission mechanism actuates a piston to move in the cylinder reciprocately. The at least one retainer is configured to fix the body and the motor. A first end of at least one retainer is engaged on the body, and a second end of the at least one retainer is engaged on the motor so that the motor is fixed on the body without using any screws.
