Embodiment
In the utility model, it is to be understood that term " interior ", " outer ", " axial direction ", " radial direction ", " longitudinal direction ", " horizontal stroke
To ", " circumference ", the orientation of the instruction such as " height " or position relationship be based on orientation shown in the drawings or position relationship, also with reality
The orientation or position relationship that border uses are corresponding, are for only for ease of description the utility model and simplify description, rather than instruction
Signified device or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to this
The limitation of utility model.
The utility model provides a kind of earthing or grounding means attachment structure of motor, and the motor includes shell 1, the connection
Structure includes the riveting column 2 being formed on the shell 1 and the riveted holes 4 being formed on the earthing or grounding means 3, the riveting column
2 can pass through the riveted holes 4 that the earthing or grounding means 3 is connected on the shell 1.
In the earthing or grounding means attachment structure of motor of the present utility model, riveting column 2 is formed on the shell 1 of motor, is adopted
With by riveting column 2 through in the riveted holes 4 of earthing or grounding means 3, so that earthing or grounding means 3 is riveted on the shell 1 of motor；Eliminate
The structures such as screw, rivet, the attachment structure of earthing or grounding means 3 and motor is simpler and Joining Technology is more convenient；Also, by direct
