ある。FIG. 2 is a schematic longitudinal cross-sectional view of the essential parts showing the configuration of an embodiment of the wiper link pivot device according to the present invention, and FIG.
Shaft 1
A flange 3 with a diameter larger than the outer diameter of the shaft base 1' is formed by forging at one end, and a shaft l is connected to this flange 3.
forming a shaft end portion 1″′ having approximately the same diameter as the base portion 1′ of the shaft;
A protrusion 6 forming an acute angle in the shape of a Laurent I is provided on the entire end surface of the shaft end 1'' side of the flange 3, and the shirt 1-
Oi: A knurling 2 similar to the conventional one is provided in the A part 1"', and after press-fitting the shaft end 1"' into the hole 5 of the lever 4, the end face of the shaft end l"' is caulked to connect the shaft 1 with the shaft end 1"'. The lever 4 is connected to the lever 4. Note that 7 is a wiper arm.

ゆるみを阻止することが出来る。With the shaft and lever configured as described above, a large torsional torque acts on the shaft 1 as a driving force that causes the wiper arm 7 and the wiper blade (not shown) to perform a pl-movement motion along the glass surface, but the shaft 1 is similar to the conventional shaft. In addition to the strength equivalent to the pressing force of the knurling 2 on the end 1"' into the lever hole 5, when the shaft end 1"' is swaged to the 'i+'J surface of the lever 4, the entire flange end surface of the shaft is The knurled protrusions provided on the periphery bite into the blade, creating a large resistance that greatly increases the torsional strength of both the shaft and lever parts, and prevents loosening due to overload of the blade resistance.
なお、フランジ部の突起はフランジを鍛造する際同時成

ある。As mentioned above, in the wiper link pivot device according to the present invention, -ζ has a flange at one end of the shaft having a diameter larger than the outer diameter of the shaft base, and a shaft end connected to this flange and having approximately the same diameter as the shaft base. A knurled protrusion is provided on the entire circumference of the 011'i surface on the shaft end side of the flange, a knurling is provided on the outer periphery of the shaft end, and after the shaft end is press-fitted into the hole of the lever, the shaft end surface is swage to connect the shaft and lever.
In addition to the strength equivalent to the pressing force of the knurling on the end face of the shaft into the lever hole as in the past, the row 1 groove-shaped protrusion provided all around the flange end face of the shaft bites into the end face of the lenoma, so that the shaft and the renoma are strong. This has a great effect in that the bonding strength of the blade can be greatly improved and loosening due to overload of the blade resistance can be prevented.
