Title:
WIPER DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/063047
Kind Code:
A1
Abstract:
Provided is a wiper device with which the chattering phenomenon of a wiper blade is suppressed with a simple structure, and which can easily improve the quietness of the wiper device. A wiper blade 30 is provided with a tilt mechanism TM1 that tilts the wiper blade 30 relative to a surface 11a such that the center Ct1 of a U-shaped hook part 23b is disposed more to the front in a wiping direction than the center Ct2 of blade rubber 50. This makes it possible to correctly tilt the blade rubber 50 relative to the surface 11a during each of forward wiping and return wiping of the wiper blade 30. Therefore, it is possible to inhibit the occurrence of defects caused by the blade wiper 50 not being able to correctly tilt relative to the surface 11a (chattering phenomenon, reversing defect, premature wear of rubber, increase in lift during high-speed travel, etc.). The present invention makes it possible to easily improve the quietness of the wiper device 10 without adding new components.
