ABSTRACT:
A mechanism for automatically regulating tension of wires employed in a window regulator comprising a drum being provided for rotational movement within said housing, and having a first side surface provided with a first ratchet teeth, a second side surface provided with a first engaging portion for engaging a first wire end, and a peripheral surface as winding surface; a ratchet plate being adjacent to said drum coaxially, and having a surface provided with a second ratchet teeth engaging said first ratchet teeth and a second engaging portion engaging a second wire end; a spiral spring having one end engaged with said ratchet plate and having the other end engaged with said housing, and urging said ratchet plate in such direction that said first ratchet teeth and said second ratchet teeth are moved idly; an elastic member axially urging said drum toward said ratchet plate; and a shaft for operating said drum to rotate by means of engaging with said drum. The mechanism of the present invention can employ a spiral spring having a larger diameter, and therefore, functions of regulating tension of wires and of balancing the force for raising a window glass with the force for lowering the window glass operate smoothly.
