Generally, a wiper device installed in an automobile is a device for wiping dust, rain or snow off the surface of a wind shield glass to secure a clear visibility while driving. Basic wiper devices include an electric motor that provides driving force, a wiper arm that reciprocates by the electric motor, and a wiper blade that wipes the glass surface along the trajectory of the wiper arm.

Since the basic wiper device has a fixed wiper arm length, the wiper blades wipe the glass while maintaining the same radius from the central axis of the wiper arm when the wiper device reciprocates.

In automobiles, the wiper device is generally mounted on the front or rear windshield glass, and the wiper device mounted on the front windshield glass is generally two pairs of wipers for wiping the glass. In the case of using a basic wiper device, there are areas where the wiper blades do not reach, and the upper glass of the front windshield glass, which is located in front of the cockpit, corresponds to the unreachable region. This undelivered area not only impedes the driver's visibility in rainy weather, but also makes it difficult for the driver to recognize the traffic light and detect the pedestrian, thereby preventing safe driving.

In addition, the smaller the undelivered area, the driver can secure a wider view and enjoy driving with a relatively comfortable mood.

In particular, in the case of wiping the windshield glass, which is relatively wider than the height, with the basic wiper device, the unreached area of the wiper blade increases significantly because the size of the wiper arm and the wiper blade is limited to the height of the glass.

In many countries, for the sake of safety, the minimum extent to which wiper devices can be wiped from windshield glass is indirectly increased, which indirectly limits the free creation of automotive design.

Therefore, as a device for reducing the undelivered area of the wiper device, Korean Unexamined Utility Model No. 1998-034420 proposes a “variable center type wiper operating structure”.

Since the wiper loader 4 moves up and down along the circumferential surface of the guide cam 3 while being rotated by the motor shaft 2, the blade can wipe a wide area. However, since the guide cam 3, which is a flat cam, is used to raise and lower the wiper loader 4, it takes up a lot of installation space. That is, the radius of the guide cam 3 will be at least 13 cm to 15 cm larger than 10 cm to increase the reach area of the blade 8 by about 10 cm, and the housing for accommodating the guide cam 3 has a diameter of at least about 30 cm. Will have If the wiper device occupying this installation space is installed on the front windshield glass respectively, it will not look good, but may interfere with the driver's vision.
