A wiper device 1k that supports the wiper blade 2a (not shown in FIG. 3) at its tip.
2 d 1nft, the 1 Neuper 1k 2 d
A wiper spring 2e serving as a suppressing means for pressing the wiper blade 2a against the front windshield 1 is interposed between the wiper blade 2a and the head 2b together with a pressing force adjusting means 5 to be described later. And, on the inner surface of the Dana 2C described in "-", a vibration sensor 1/3 is arranged as a chatter detection means for detecting the chatter state of the wiper 2.
Between the wiper arm 2d and the head 2a, a T1-shaped pressing force adjustment stage 5 made of a shape memory alloy is provided in series with the wiper spring 2e. When the temperature is higher than a predetermined temperature, the pressing force adjusting means 5 operates as shown in FIG.
It has the property of being in such an elongated state that it shrinks and deforms as shown in FIG. 4 when it is heated to a temperature above a predetermined temperature. Therefore, the wiper spring 2e is expanded by the contraction movement of the pressing force adjusting means 5, and the wiper blade 2a is expanded.
The front window is configured to increase the pressing force on the lath 1, while the expansion movement of the pressing force adjusting means 5 causes the wiper spring 2e to be accommodated, thereby reducing the pressing force on the wiper blade 2a.

As a result, wiper spring 2
As the amount of cotton e is absorbed, the pressing force of the wiper blade 2a is reduced to a small extent, and as a result, the chattering state of the wiper 2 is eliminated. Therefore, the raindrop wiping effect can be more effectively exerted, and the running safety of the vehicle can be improved. Incidentally, the pressing force adjusting means 5 can also be constituted by shape memory alloy idiot wax pellets.
