[0010] Preferably, one end of the limit spring is fixedly connected to the first arm, and the other end of the limit spring is designed as a hook-shaped structure and is engaged and connected with the limit seat.

[0011] Beneficial Effects

[0012] The utility model provides a novel non-erection type rear wiper arm structure. Compared with the prior art, it has the following beneficial effects:

[0013] This new non-erectible rear wiper arm structure, by providing an arm seat, a rubber shock-absorbing pad and a wiper arm, uses the rubber shock-absorbing pad to reduce the impact force between the wiper arm and the arm seat when the wiper arm is affected by external force, thereby preventing damage to components and increasing the robustness of the design. When the car body is cleaned by a car washing machine, the risk of the wiper arm breaking due to the impact of automatic car washing is reduced, thereby increasing the service life of the wiper.
