In addition, vibration noise generated in the operation process of the motor assembly can be effectively improved, and the production cost of a user on the clothes treatment device with the motor assembly is improved.
The reinforcing structure 130 is disposed on the transmission member 120, and the rigidity of the reinforcing structure 130 is greater than that of the plastic member, that is, the transmission member 120 is provided with the reinforcing structure 130 with greater rigidity, so that the mechanical performance, such as the structural strength, of the transmission member 120 can be effectively improved, and the service lives of the transmission member 120 and the motor assembly can be further prolonged.
According to a second aspect of the present utility model, there is provided a laundry treating apparatus comprising the motor assembly according to any of the above embodiments, thereby having all the advantageous technical effects of the motor assembly, which will not be described herein.
