Abstract:
1. A wiper for a vehicle comprising: an elongated wiper strip having a wiping portion for wiping a surface to be wiped and a base portion; at least one backing extending in a longitudinal direction of the wiper strip, the backing imparting rigidity and resiliency to the wiper strip; a blade holder for holding the wiper strip and the backing at longitudinally middle portions of the wiper strip and the backing, the blade holder including a blade holding portion, the blade holding portion surrounding the base portion and the backing at the longitudinally middle portions and holding the base portion and the backing to restrict movement of the base portion and the backing each in a direction perpendicular to the longitudinal direction, the blade holder also including a pair of side surfaces facing in opposite directions; a coupling member having a pair of side walls facing the corresponding side surfaces, the coupling member being attached to the blade holder such that the coupling member is allowed to rotate about a rotational axis perpendicular to each of the two side surfaces; and a wiper arm having a distal coupling portion attached to the coupling member, wherein an engagement projection is formed on an outer side surface of each of the side walls of the coupling member, each of the engagement projections has an upper end surface and a lower end surface, the upper end surface and the lower end surface extending in the longitudinal direction of the wiper strip, the upper and lower end surfaces being parallel to each other and facing in opposite directions, the distal coupling portion has an upper cover wall for substantially covering an upper surface of the coupling member and a pair of side cover walls for substantially covering the outer side surfaces of the corresponding side walls, each of the side cover walls of the distal coupling portion includes an engagement recess that has an opening facing a longitudinal distal end, when the distal coupling portion is attached to the coupling member, each of the engagement projections is inserted into the corresponding engagement recess through the associated opening and is moved longitudinally in a state in which the corresponding engagement recess is engaged with the upper and lower end surfaces of the engagement projection in the vertical direction, the distal coupling portion has a stopper portion, the blade holder includes a stopper wall portion, and the stopper wall portion contacts the stopper portion in the longitudinal direction in a state in which the distal coupling portion is arranged at such a longitudinal position relative to the coupling member that each engagement recess and the corresponding engagement projection are not engaged with each other.
