The holding device 15 by this assembly prevents the substrate 12 from being depressed inside the holding device 15 by the pressing plate 16 provided at the tip of the holding device 15 and the engagement pieces 18a provided on both sides. The holding plate 14 in which the elastic lever is viewed from the opening 15a of the holder 15 is accommodated in the holding member 15 with the elastic force held by the inside of the holding member 15 and the side stopper 20b.

FIG. 3 is a partially cutaway perspective view showing a state in which the rotating tool 12 is fitted inside the curved folded portion 13 of the substrate 12 of the intermediate support tool 11.

The rotating tool 21 is provided on one end face with the intermediate support 1.
A curved surface 22 having a U-shaped cross section is formed so as to fit inside the curved folded portion 13 of the substrate 12, which is one of the components . Ma
Further, guide walls are formed on both sides of the curved surface having a U-shaped cross section.
You. The curved surface side of the rotary member 21 between the both side of the guide wall
And a wiper supporting portion 31 formed on the back surface of the wiper 2.
An engaging hole 23 having an Ω-shaped cross section is provided for engaging with the support pin 32 which is supported by being axially penetrated through the through hole. By this <br/> and fitting the engaging hole 23 of the rotating member 21 is matched to the supporting pins 32, ing to Rukoto rotatably allowed fitted-engaged with the rotary member 21 to the support pins 32.

The lower extension of the curved surface 22 of the rotating tool 21 has a projection 24a which engages with the locking hole 24b of the substrate.
And a lever 25 for releasing this engagement is provided at the tip thereof.

The wiper support portion 31 is formed on the back surface of the wiper 2, and has a substantially central portion into which the engagement hole 23 of the rotating tool 21 is inserted, and a support pin 32 for rotatably supporting the wiper support portion 31. Is provided.

The wiper connecting and holding member constructed as described above is attached to the wiper support 31 on the back of the wiper 2.
In order to attach the rotating tool 21 to the support pin 32 pivotally supported by the wiper support portion 31,
Is fitted. Next, the curved folded portion 1 formed on the substrate 12 held by the holding member 15 constituting the intermediate support member 11
3 between the guide walls provided on both sides of the rotating tool 21.
And the inside thereof is fitted with the curved surface 22 of the rotating tool 21, and the rotating tool 21 is sufficiently pushed into the inside of the curved folded portion 13 of the substrate 12 so that the projection 24 a of the rotating tool 21 is engaged with the substrate 12. The intermediate support 11 and the rotating tool 21 are assembled by firmly engaging with the stop holes 24b.

The distal end of the arm 1 is inserted between the base plate 12 and the holding plate 14 disposed on the holding member 15 which is a constituent material of the intermediate support member 11, and the arm is inserted into the holding hole 1b formed in the holding plate 14. And the projection 1a formed on the arm 1 are engaged with each other to
And the substrate 12 to clamp and fix the arm 1. Thus, the wiper 2 is connected and held to the arm 1.

When the wiper 2 is rotated at an arbitrary angle with respect to the arm 1, if the wiper 2 is rotated as it is, the wiper support 31 rotates around the support pin 32.

When the wiper 2 is to be removed from the arm 1, the elastic lever 14a at the rear end of the holding plate 14 disposed on the holding member 15, which is a component of the intermediate support member 11, is pulled up in the reverse procedure. Locking hole 1b of holding plate 14 and arm 1
Can be easily removed by releasing the engagement of the arm 1 with the projection 1a and pulling out the arm 1 from the intermediate support 11.
