[0037] Among them, the frame body 231 and the vibration damping plate 13 can be along such a path Figure 3 The first direction of the arrangement is shown, and this first direction can be the same as the axial direction of the transmission device 10. The planetary gear 21 can be rotatably mounted on the frame body 231. The connecting part 232 is fixedly connected to both the frame body 231 and the damping plate 13. In other words, the connecting part 232 can be connected between the frame body 231 and the damping plate 13. The connecting part 232, the frame body 231, and the damping plate 13 can jointly define the installation space 3. Part of the planetary gear 21 can be located within the installation space 3 to protect the planetary gear 21, which is beneficial for the stable operation of the planetary gear 21.
