ABSTRACT:
A window regulator includes a main arm, a first sub-arm, and a second sub-arm. The main arm has a hole through it. A flange member surrounds the hole. The first sub-arm includes a shaft section which projects through the hole and is secured to the second-sub arm. In one embodiment, the distal edge portion of the flange member is curved. In a second embodiment, the flange member extends transversely from the main arm, and a low-friction member is between the distal edge portion of the flange member and a surface portion of the first sub-arm. In a further embodiment, the main arm and the second sub-arm have sliding surfaces in contact with each other, and a concave lubricant holding portion is provided on one of the sliding surfaces. The window regulator reduces noise during raising and lowering of the window and ensures rigidity of the first sub-arm.
