Wiper blade and wiper for vehicle

A wiper blade comprising:

• an elongated wiper strip including a base portion and a wiping portion, which wipes a wiped surface;
• a leaf spring backing that extends along a longitudinal direction of the wiper strip and provides the wiper strip with rigidity and resilience;
• a blade holder directly or indirectly coupled to a wiper arm, wherein the blade holder is coupled to the backing to restrict movement of the backing in the longitudinal direction, the blade holder includes a blade holding portion that surrounds the base portion of the wiper strip and the backing at a longitudinally central portion of the wiper strip and the backing, and the blade holding portion holds the wiper strip and the backing to restrict movement of the wiper strip and the backing in a direction orthogonal to the longitudinal direction;
• two cases opposed to each other and arranged at two longitudinal ends of the blade holder, wherein each of the cases includes a case holding portion surrounding the base portion of the wiper strip and the backing, and each case holding portion holds the wiper strip and the backing to restrict movement of the wiper strip and the backing in the direction orthogonal to the longitudinal direction;
• a movement restriction member coupled to and engaged in the longitudinal direction with the backing and the blade holder to restrict relative movement of the backing and the blade holder in the longitudinal direction;
• and
• a coupling member that is pivotally coupled to the blade holder and coupled to the wiper arm, wherein
• the movement restriction member is fitted and coupled to the backing and the blade holder in a certain direction, and
• the coupling member includes a separation restriction portion that restricts separation of the movement restriction member in a direction opposite the certain direction.
