It is connected by a link 7 via 6. Further, among the rear blades 4, a notch recess 4a is formed on the front edge side of the blade 4 located at the center as shown in the drawing, and a connecting shaft 8 is integrally formed on the front edge side. A grip 9 is slidably attached to the central blade 3 of the front blades 3 thus provided.

Like the blades 3 and 4, the handle 9 is made of a synthetic resin material, and the handle body 10 has a predetermined width H and integrally has upper and lower holding pieces 11 and 12 for holding the front blade 3. However, locking claws 13 that engage with the rear edge 3a of the front blade 3 are formed on the left and right of the end portion of the upper holding piece 11, and the rear blade 4 is provided at the substantially central portion of the end portion of the lower holding piece 12. The pair of connecting pieces 14 are formed so as to extend at predetermined intervals so that the connecting shafts 8 can be fitted therein, and the base ends of the connecting pieces 14 slidably contact the rear edge 3a of the front blade 3. Has been done. The handle 9 thus formed is forcibly clamped from the front edge side of the front blade 3, and the connecting piece 14
A connecting shaft 8 is housed in between and is connected to the rear blade 4. In this state, the front edge 3b of the front blade 3 is in sliding contact with the handle 9.

Since it is indirectly elastically attached to the surface 28a, even if the spring member 47 has burrs or the like, for example, the vertical surface 28a
a can be prevented from being damaged, and the resin plate 46 intervenes to make a surface contact with the vertical surface 28a, so that the feeling can be improved, and the assembly between the parts can be improved. The play in time is eliminated, and it is possible to prevent the generation of abnormal noise during traveling. Further, even if the interior of the vehicle is exposed to a high temperature and a heat change occurs in the parts, the operating load does not decrease due to the elastic performance of the spring member 47, and a stable operating load can be maintained for a long period of time, and the handle operation The direct feeling can be maintained and the load can be obtained on the handle portion, so that it is not necessary to separately provide the load on the rear blade 30 side. Further, the resin plate 46 and the spring member 47 for taking out the load are the upper and lower front blades.
Since it is located on the back side of 28A and 28B, it is difficult to see from the design surface side, so that the appearance can be improved. Further, since the regulation piece 39 is provided to form a slight gap between the handle body 37 and the front edges of the front blades 28A, 28B, the front edges of the blades 28A, 28B are not damaged, and the design beauty is ensured. can do.

The operation load value can be easily set by changing the plate thickness and the bending deformation amount of the spring member 47.
Also, when considering only the load distribution, the ridge 29 is abolished,
The same function can be obtained even if the grip body 37 is slidably contacted with the front edges of the front blades 28A and 28B.

(Effect of the Invention) According to the present invention, a pair of connecting pieces, which are inserted between the front blades and connected to the rear blades, are formed on the back surface of the handle body so as to extend at a predetermined position of the connecting pieces. Correspondingly has a protruding protrusion, and a resin plate which slidably contacts the rear edges of the upper and lower front blades when the connecting piece is inserted into the connecting piece, and the resin plate on the rear side of the resin plate. By adopting a structure in which the spring member for pressing and biasing the blade is elastically attached to the trailing edge of the blade, damage to the trailing edge of the front blade can be prevented even if the spring member has burrs or the like. By interposing this resin plate, it comes into surface contact with the rear edge, so the feeling can be improved, and the play at the time of assembly between the parts is eliminated, and abnormal noise is generated during running. Can be prevented. Further, even if the interior of the vehicle is exposed to a high temperature and a thermal change occurs in the parts, the elastic load of the spring member does not reduce the operating load, and it is possible to maintain a stable operating load for a long period of time. Since the feeling can be maintained and the load can be obtained in the handle portion, it is not necessary to separately provide the load on the rear blade side. Further, since the resin plate and the spring member for taking out the load are located on the back surfaces of the upper and lower front blades, it is difficult to see them from the design surface side, so that the appearance can be improved.
