PURPOSE: A behavior analysis apparatus for vehicle wiper system is provided to achieve an improved accuracy of measured value by automatically and simultaneously measuring an attack angle and operating angle. CONSTITUTION: An operating angle measuring device(5) is mounted to a wiper retainer(2) which is coupled through a wiper link(1) and performs an angular motion. An attack angle measuring device(4) is mounted to the front end of a wiper arm(3) having a blade for wiping a glass(G). The attack angle measuring device includes a base having a slider shaped as a sphere so as to reduce friction when the attack angle measuring device moves along the surface of the glass; a support plate disposed onto the base; a fixing jig coupled onto the support plate, and which has a screw; a support end rotating between the fixing jig and support plate; and an arm coupler mounted to the wiper arm. The support end has a potentiometer embedded within the support end, wherein the potentiometer performs an angular motion together with the arm coupler, and converts the displacement produced from the angular motion into an electrical signal.
