Abstract
A wiper device including: a yoke for supporting a wiper strip; an auxiliary lever including a coupling protrusion coupled to a coupling hole prepared in the yoke and formed of synthetic resin; and a main lever including an assembly protrusion coupled to an assembly hole prepared in the auxiliary lever and formed of the synthetic resin, wherein the auxiliary lever includes: a first vibration prevention portion protrusively formed to contact an upper surface of the yoke on a cross section taken along a width direction of the auxiliary lever in a position where the coupling hole is disposed; and a second vibration prevention portion in which an outer circumference surface of the coupling protrusion is formed in a tapered form so that the coupling protrusion coupled to the coupling hole is fit in a direction in which the coupling protrusion is coupled to the coupling hole.
