In particular, a structure in which various accessories are combined with a kind of connecting member solves the problem of providing various types of automobile wiper arms. However, since there are many components of the wiper, in addition to cost increase, the user can use only one set of accessories during use. The remaining accessories can be wasted. Therefore, the drawback still remains from the viewpoint of use. Furthermore, the device disclosed in Patent Document 2 “Pivot of Cartilage Wiper without a fulcrum” refers to Patent Document 3 and Patent Document 4 in the background art of the specification. Of the joint structure with the spring piece, the pivot base catches a notch on the side surface of the spring piece with two pairs of fastening claws. Since the loosening of the fastening claws affects the wiping effect of rainwater, this type of structure is required to have extremely high accuracy as a measure to prevent loosening when processed. In addition, a novel “cartilage wiper structure having no fulcrum” is disclosed. The fastening claw of the wiper pivot base is inserted into the fastening hole of the spring piece and fixed. As a result, the loosening problem of the “wiper structure” disclosed in the above-mentioned US Pat. No. 5,096,83 is solved, but the elastic deformation motion of the spring piece is limited by the limiting mechanism of the fastening claw and the spring piece, and the spring piece is deformed. After that, it cannot stretch naturally, resulting in an imbalance of the ability to stick to the car glass. Furthermore, since the difficulty of punching the fastening hole is high, it affects the elastic deformation of the spring piece at that location and causes a defect. In view of these drawbacks, Patent Document 2 solves this problem by a method in which the protrusion point and the claw portion at the lower end of the pivot base are engaged with the surface of the spring piece. This eliminates the need for drilling in the spring pieces, solving the elastic deformation activity and strength problems of the spring pieces. However, the distance between the projecting points 1 is that the space before and after the deformation of the spring piece sways when the pivot base wipes rainwater, and the problem of incomplete wiping remains.
