The inner plate and the abutting plate are wound to form a side wall, and the top plate, the inner end plate and the abutting plate are sequentially connected from the outer end plate to form the end wall, and the top plate is alternately inclined in the opposite direction, The superposition | polymerization board extended from an end plate was piled up on the board | substrate, and this superposition | polymerization board was wound with the winding board extended from the other side edge of a board | substrate.
[0007]
In addition, an outer plate is connected to both side edges of the substrate, an outer end plate is connected to both end edges of one outer plate, and a top plate, an inner plate and an abutting plate that are sequentially connected from the outer plate are wound to form a side wall. The top plate, the inner end plate, and the abutting plate that are sequentially connected from the outer end plate are wound to form an end wall, the top plate is alternately inclined in the opposite direction, and the inner plate is inserted into the slit of the end wall.
[0008]
Further, in the latter, a superposition plate is extended from the outer end plate, this superposition plate is superposed on the substrate, an inward plate, a top plate and a contact plate sequentially connected from the superposition plate are wound to form a receiving wall. The abutting plate and the inner end plate of the end wall are overlapped.
[0009]
The shock absorber configured in this way has at least one side wall connected to the end wall, and the top plate is alternately inclined in the opposite direction, so that the side wall and the end wall against an impact from any direction. Is difficult to fall down and difficult to deform.
