  • Patent number: 9222295
    Abstract: A window regulator includes: a guide rail including a rail main body part, an insert-through part provided at one end of the rail main body part and inserted into a housing, and a locking tab provided at the rail main body part. The housing includes a housing part housing the insert-through part, an engaging part engaging with a tip of the locking tab, and a guide part configured to guide the tip of the locking tab to the engaging part when the tip of the locking tab is brought into contact with the guide part. The engagement of the locking tab and the engaging part restricts movement of the housing in a longitudinal direction of the rail main body part toward the one end of the rail main body part.

  • Publication number: 20140007507
    Abstract: Disclosed is a window regulator that reduces thrust-down noises by minimizing the moment of rising even when the window glass reaches the lower edge, and improves the durability of an elastic member. The window regulator (10) is provided with: a carrier plate (12) that holds the window glass; a guide rail (11) that freely guides the carrier plate up and down; a direction switching member (13) disposed at the top end of the guide rail; inner cables (16, 17) that pass over the direction changing member, and are connected to the carrier plate (12); and a drive mechanism (14) that reciprocatingly drives the inner cables. An elastic member (28) is disposed on the lower edge of the carrier plate (12). A receiving section (27), which comes into contact with the elastic member (28) and controls the descent of the carrier plate, is disposed on the drive mechanism (14) housing (25). The receiving section (27) has an inclined surface (44) inclined in such a manner as to rise with increasing distance from the guide rail.
