Title:
WINDOW REGULATOR FOR AUTOMOBILE
Document Type and Number:
Japanese Patent JP3666711
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve durability, and to decrease the number of parts by pivotally attaching first and second pulleys lifting and lowering a glass window to an internal panel, disposing a large-diametral pulley between the internal panel and a guide member and reducing the bending stress of a wire.
SOLUTION: When a motor 29 is operated by working a switch in a car, a drum 28 is rotated, a wire 31 is driven and a first pulley 16 and a second pulley 17 are turned centering around pins 18, 19. A window-glass support member 11 retained to the wire 31 is lifted and lowered with the driving of the wire 31. Sliders 12 are guided by tire guide surface of a guide member 9, and elevated and brought dot together with a window glass 6 at that time. Even when the diameters of the first and second pulleys 16, 17 are enlarged, the pulleys 16, 17 do not interfere in the window-glass support member 11 while the curvature of the wire 31 is increased, and large bending stress is not generated. When the pulleys 16, 17 are revolved, large vibrations are not generated. Accordingly, the number of parts is decreased, and durability can be improved.
