Conventionally, upper and lower pulleys are attached to the upper and lower parts of the guide member that guides the window glass holding member up and down.
A drum is placed on the side between the upper and lower pulleys, a wire is stretched between the drum and the upper and lower pulleys in a triangular shape, and the holding member is moved up and down via the wire by rotation of the drum using a handle, etc., and the window is closed. A window regulator that opens and closes glass has been proposed.

該ブレーキ部材２７の摩擦トルクT2は、上記
摩擦ブレーキコイルスプリング１９の空転トルク
T1より大きくロツクトルクT3より小さく設定す
る（T1＜T2＜T3）。 The friction torque T 2 of the brake member 27 is equal to the idling torque of the friction brake coil spring 19.
Set the locking torque to be greater than T 1 and smaller than T 3 (T 1 < T 2 < T 3 ).

てゆく。 If the window regulator is configured as described above, when the handle 17 is rotated in the downward direction D of the window glass 2, the wire 21 is unwound from the drum body 13, and the wire 22 is unwound from the drum body 1.
3 and the window glass 2 is lowered.

けワイヤ２１が引つ張られて張設されるまで、ド
ラム本体１３のみが僅かに回転する。 When the window glass 2 is lowered to its lowest position, the wire 21 is loosened and the wire 22 is tightened. Next, when the handle 17 is rotated in the upward direction U of the window glass 2, the friction torque of the brake member 27 is increased.
Since T 2 is larger than the idling torque T 1 of the friction brake coil spring 19, the support member 18 is fixed by the brake member 27, and the drum body 1
Only the drum body 13 rotates slightly until the wire 21 is stretched by the amount of loosening at the edge of the wire insertion hole 13a of No. 3.

本のワイヤで本案の機能を果すこともできる。 Then, when the wire 21 is tightened to the extent that it is loosened, the operating force of the handle 17 is greater than the friction torque T 2 of the brake member 27, so the support member 18 rotates while being pulled by the wire 21, and the wire 21 The wire 22 is wound around the drum body 13 in a state where there is no slack, and the wire 22 is wound around the drum body 13.
The window glass 2 is then unwound from the window and the window glass 2 is raised. In addition, in the above embodiment, the handle 1
Although a manual type using a motor 7 has been exemplified, it goes without saying that it is also applicable to an electric type using a motor. Furthermore, in the embodiment, the wires 21, 2
2. However, by passing part of the wire through the holding member 4 and fixing it to the holding member 4, 1.
A book wire can also perform the function of the present invention.

A friction brake coil spring is wound around the boss part of the drum body to which the wire on the lower pulley side is fixed, and the boss part of the support member to which the wire on the upper pulley side is fixed, and a brake member is provided on the support member. Therefore, the relationship between the idling/locking torque of the friction brake coil spring and the friction torque of the brake member can absorb the slack in the wire when the window glass is raised, so that the window glass can be raised and lowered smoothly. In addition, since there is less play compared to the type that uses a ratchet, the wire can be stretched steplessly and the looseness when assembling the drum can be set roughly.
