This can save material by minimizing an unnecessary area compared to the bumper covering all of the rear edge described above.

In addition, the cell phone bumper 1000 according to an embodiment of the present invention can improve both the cushioning effect and durability by applying a material of one side in contact with the cell phone P and a material of one side exposed to the outside differently.

In general, the cell phone bumper 1000 uses a single synthetic resin to minimize manufacturing costs, and is manufactured by a single injection process, so that the inside and outside surfaces are usually made of the same material. However, in this case, if the softness of the synthetic resin is excellent, the impact buffering effect is excellent, but the hardness is low, so it is weak against scratches and tears, and durability may be reduced. It is easily damaged when used for a long period of time and causes the lifespan to be reduced.

Conversely, if the hardness of the synthetic resin is high, durability is improved, but it is difficult to expect a buffering effect because the impact energy cannot be effectively absorbed at the time of impact.

However, in the cell phone bumper 1000 according to an embodiment of the present invention, the cell phone bumper 1000 and the cell phone P are in contact with the first member 100 which is relatively soft and wraps the cell phone P to provide a shock-absorbing effect. and the surface exposed to the outside of the cell phone bumper 1000 was wrapped around the first member 100 with a second member 200 having relatively better hardness than the first member 100 to supplement durability. . 1, the cell phone bumper 1000 has been described as an example that the two corners of the cell phone P meet vertically in a memory "a" shape, but it is not limited thereto, and various shapes such as circles, spheres, polygons, etc. It is apparent to those skilled in the art that it can be transformed into
