ABSTRACT:
A wiper blade is provided with an improved lever to yoke connection. The lever has a yoke-fitting part at each end defining a hooking hole with an opening which opens towards the opposite hooking hole. The yoke-fitting part includes an engaging part and a projection which defines the opening. The yoke has a lever-fitting part including a lever-setting shaft for engagement with the hooking hole. To prevent the yoke from dropping off the lever, a protrusion is provided on the lever. The particular wiper blade allows easy assembly and improved strength of the yoke.
