Wiper device having improved durability
A wiper device having improved durability includes: an arm head having one end fixed to a pivot shaft installed on a vehicle; and a retainer having one end coupled to the arm head to rotate relative to the arm head and the other end coupled to a blade for wiping a glass of the vehicle, wherein the retainer includes: a body formed of synthetic resins; and a reinforcement member that is coupled to a portion of the retainer, which is adjacent to the arm head, and is formed of a metal material.
1. A wiper device having improved durability, the wiper device comprising:
an arm head having one end fixed to a pivot shaft installed on a vehicle; and
an elongated retainer having one contoured end coupled to the arm head to rotate relative to the arm head and an opposite end coupled to a blade for wiping a glass of the vehicle,
wherein the retainer comprises:
an elongated body formed of synthetic resins, one end of which partially forms the contoured end; and
a reinforcement member that is coupled to within a portion of the elongated body, which is adjacent to the arm head, and is formed of a metal material,
wherein the reinforcement member is a member having a plate shape, and an exterior edge contour of the reinforcement member follows the contour of the one end of the retainer, the reinforcement member being manufactured by trimming a metal having the plate shape to have the same shape as the shape of the end of the retainer via molding, and
wherein the exterior edge of the reinforcement member includes a first lock back portion and a second lock back portion, and the first lock back portion and the second lock back portion are grooves formed concavely to accommodate a stopper disposed in the arm head.
2. The wiper device of claim 1 , wherein the reinforcement member is coupled to the body by an insert molding method.
3. The wiper device of claim 1 , wherein the reinforcement member comprises a pair of reinforcement members disposed symmetrically to each other, and the pair of reinforcement members are disposed to be spaced apart from each other.
