It is formed in a long circular plate with a radius of 300 mm. In the middle of the elongate direction, a fourth engagement portion 29 that is 9 mm in the elongate direction and rises 2 mm upward is formed. The terminal of the second vertebra 13 has a fifth engaging portion 30 which is 4 mm long in the longitudinal direction, rises 2 mm upward, and has a 60-degree chamfer.
[0022]
Next, the state of assembling the wiper 10 configured as described above will be described. First, as shown in FIG. 11, the first vertebra 12 and the second vertebra 13 are arranged such that the second vertebra 13 is disposed below the first vertebra 12, and the first engagement portion of the first vertebra 12 is formed. The fourth engaging portion 29 of the second vertebra 13 is engaged with the upper side of 20. Next, the terminal of the second vertebra 13 is inserted through the first opening 21 of the first vertebra 12, and the second engagement portion 22 is inserted into the second engaging portion 22 through the second opening 24 of the first vertebra 12. The fifth engaging portion 30 is locked. By doing so, the first vertebra 12 in a flat plate shape is held by the second vertebra 13 in an arc shape in a state of being bent in an arc shape. That is, by appropriately setting the curvature, plate thickness, hardness, and the like of the second vertebra 13, it is possible to appropriately cope with the pressing force from the driving member 5, the curve of the wiping member 2, and the like.
[0023]
Next, as shown in FIG. 12, the other 16b of the refill 11 in which the second groove 16 is open is applied to the claws 18 of the assembled first and second vertebras 12 and 13, as shown in FIG. 13. Thus, the second groove 16 and the claw 18 are engaged by being shifted to the right. Then, as shown in FIG. 14, when the claw 18 reaches the closed one 16a of the second groove 16, as shown in FIG. 15, the cap 31 having an L-shaped cross section engaged with the first vertebra 12 as shown in FIG. Hit. At this time, at the same time, the free end of the claw 18 gets over the projection (not shown) of the second groove 16 and re-enters the recess of the second groove 16, so that the refill 11 can move the first vertebra 12 and the second vertebra 13 together. This sliding work is completed by being able to prevent falling off from the assembled one. In addition, the refill 11 is held by a set of the first and second vertebras 12 and 13 which are fixed to be bent in an arc shape, so that the refill 11 itself also has an arc shape.
[0024]
As shown in FIG. 1, the cap 31 is in contact with an end of the cover 25, and the cover 25 attaches the leg 25 a of the cover 25 to the first vertebra 12 as shown in FIG. 16. The notch 19 faces the notch 19 from the second opening 24, and is engaged with and supported by the notch 19.
[0025]
The cover 25 is held on the first vertebra 12 and the second vertebra 13 as described above so as to protect the first vertebra 12 and the second vertebra 13 made of flexible rubber or plastic. Have been. The cross section of the cover 25 has one lower side and the other higher side. The high portion is formed in a bank-like shape, and is formed in a shape easily susceptible to wind pressure and the like during traveling. Since the wiping portion 11b of the refill 11 is designed so as not to rise from the wiping surface 2a of the wiping member 2, the wiping property is maintained.
[0026]
In the wiper 10 having the above configuration, when the wiping portion 11b of the refill 11 is deteriorated, only the refill 11 is replaced by making the claws 18 formed on the first bartaibler 12 enter and exit the second groove 16 of the refill 11. This makes it unnecessary to replace the entire wiper 10. This results in effective use of resources and reduction of the burden on consumers. Further, depending on the specifications of the refill 11, there are a refill for wiping raindrops and a refill for removing snow, but in the case of such replacement, only the refill 11 has to be replaced, and the entire wiper 10 does not need to be replaced. Will be. This also results in effective use of resources and reduction of the burden on consumers. In addition, since the combined body of the first and second vertebras 12 and 13 is held by the pawls 18, the overall height is reduced, the rolling during the operation of the wiper 10 is reduced, and the wear resistance of the refill 11 is improved. I do.
[0027]
Also, since the first and second vertebras 12 and 13 are formed by bending in an arc shape, the refill 11 supported by the first and second vertebras 13 is urged to rotate toward the wiping surface 2a, so that a pressing means such as a spring is used. In spite of the wiper having no wiper, the wiper can be pressed flush against the wiping surface 2a. In addition, since the first and second vertebras 12 and 13 are connected and supported, the refill 11 is securely supported by the connecting member 14 via the first and second vertebras 12 and 13.
[0028]
In addition, the first vertebra 12 and the second vertebra 13 are connected by a first engagement portion 20 and a fourth engagement portion 29 at a central portion, and a second engagement portion 22 and a fifth engagement portion are provided at both ends by a second engagement portion 22. Since the two members 12 and 13 can be connected and supported only by being engaged with the part 30, the assembling is simple and easy.
[0029]
Further, since the refill 11 can be pressed against the wiping surface 2a by the cover 25, not only can the floating of the wiper 10 be prevented, but also decorative addition is possible.
[0030]
【The invention's effect】
According to the first aspect of the present invention, when the refill is deteriorated, the refill groove can be put in and out of the claw formed on the first vertiver, so that only the refill can be replaced, without replacing the entire wiper. Will also be good. This results in effective use of resources and reduction of the burden on consumers. Also, depending on the refill specifications, there are refills for wiping raindrops and refills for removing snow, but in the case of such replacement, only the refill needs to be replaced, and the entire wiper does not need to be replaced. . This also results in effective use of resources and reduction of the burden on consumers. Further, since the combined body of the first vertebra and the second vertebra is held by the pawl, the overall height is reduced, the rolling during operation of the wiper is reduced, and the abrasion resistance of the refill is improved. In addition, since the connecting member is rotationally urged toward the wiping surface by the driving member, the connecting member can be pressed flush against the wiping surface despite being a wiper without a lever that is a pressing member. Further, since the vertebra is connected and supported, the refill is securely supported by the connecting member via the vertebra. Furthermore, the first and second vertebras are fitted only by the first and fourth engagement portions formed at the center portion and the second and fifth engagement portions formed at both end portions, and both are engaged. Can be connected and supported, so that assembly is simple and easy.
