LINKAGE SHAFT UNIT OF A WIPER SYSTEM TO FORM A HANGING SILL, A THREAD AND A NULL SERRATION IN A BODY OF THE LINKAGE SHAFT, TO FORM A SERRATION INSIDE A COMBINATION MEMBER OF A PLATE AND TO COMBINE THE COMBINATION MEMBER IN THE THREAD

摘要

PURPOSE: A linkage shaft unit is provided to firmly fix a plate in a body of the linkage shaft, to prevent the separation of an injection base to the exterior and to remove potential defect factors between the linkage shaft and the plate. CONSTITUTION: A hanging sill is formed in an outer circumference of a body(42) of a linkage shaft(40) to prevent the backward movement of a plate(44). A thread(58) is formed in front of the plate to combine a combination member(56). Therefore, the plate and an injection base(48) to be combined on the linkage shaft are firmly fixed without separating from the linkage shaft.
