As shown in FIG. 3, a housing portion 41 is provided inside the end cap 40 . As shown in FIGS. 1 and 2, the ends of holder 30, blade rubber 10 and vertebra 20 are inserted into receiving portion 41 of end cap 40 (FIG. 3). In other words, the end cap 40 collectively covers the ends of the holder 30, the blade rubber 10 and the vertebra 20. As shown in FIG. The end portions of the holder 30, the blade rubber 10 and the vertebrae 20 are inserted into the receiving portion 41 (FIG. 3) of the end cap 40 along the direction of the arrow shown in FIG. 2 (the longitudinal direction of the vertebrae 20 etc.) be done. Therefore, in the following description, the direction of the arrow shown in FIG. 2 may be called "insertion direction".

As shown in FIGS. 3 and 4, the end cap 40 is provided with a first retaining portion 51 and a second retaining portion 52 that can be engaged with the vertebra 20 shown in FIG. Specifically, the end cap 40 is integrally formed with a pair of elastic pieces 53 extending along the longitudinal direction of the vertebra 20 (FIG. 2). In other words, each elastic piece 53 extends from the front in the insertion direction toward the back. Furthermore, one longitudinal end (base end) of each elastic piece 53 is a fixed end, and the other longitudinal end (tip) is a free end.

Each elastic piece 53 forms part of the bottom wall of the end cap 40 , and the upper surface of each elastic piece 53 forms part of the bottom surface 41 a of the housing portion 41 . A first retaining portion 51 is formed on the free end side of each elastic piece 53 . The upper surface 51a of the first retaining portion 51 is inclined so as to gradually approach the ceiling surface 41b of the accommodating portion 41 along the insertion direction. That is, the upper surface 51a of the first retaining portion 51 is an inclined surface that gradually rises along the insertion direction.

After that, the lip portion 13 (FIG. 1) of the blade rubber 10 is pinched and the blade rubber 10 is pulled along the holder 30 (FIG. 1). Then, the blade rubber 10 is pulled into the holder 30 (FIG. 1) through the gap S.

As is clear from FIG. 6, the end cap 40 covers the ends of the two vertebrae 20a, 20b not only in the first position but also in the second position. In other words, the two vertebrae 20a, 20b remain constrained by the end cap 40 while the blade rubber 10 is being replaced. Although not shown in FIGS. 5 and 6, the end cap 40 is positioned not only at the ends of the vertebrae 20a and 20b but also at the holder 30 in both the first position and the second position. It also covers the ends of Therefore, the blade rubber 10 can be replaced while maintaining the integration of the components (vertical bras 20a, 20b and holder 30) by the end cap 40. FIG.

When the end of the vertebra 20 is inserted into the housing portion 41 of the end cap 40, the end of the vertebra 20 comes into contact with the front surfaces 52a of the two second retaining portions 52 shown in FIG. The space between the second retaining portions 52 facing each other is widened to advance beyond the second retaining portions 52 . At this time, since the front surface 52a of each second retaining portion 52 is a curved surface, the end portion of the vertebra 20 can smoothly pass between the two second retaining portions 52. As shown in FIG. The end of the vertebra 20 that has passed through the second retaining portion 52 abuts on the upper surfaces 51a of the two first retaining portions 51 shown in FIGS. While pushing down (while bending the elastic piece 53), it advances beyond the first retainer 51. As shown in FIG. At this time, since the upper surface 51 a of the first retaining portion 51 is an inclined surface, the end portion of the vertebra 20 can smoothly pass through (get over) the first retaining portion 51 .

As shown in FIG. 2, the tip of the vertebra 20 is provided with a recess 23 . On the other hand, as shown in FIG. 4 , convex portions 42 are provided on both sides of the front surface 41 e of the accommodating portion 41 .
