The spring adjuster 4 passes through a guide block 13 which is inserted into the frame body 7a so as to be freely raised and lowered, and can slide vertically through the guide block 13, and its upper end is connected to the lower end of the torsion plate 11. and a spring adjusting shaft 15 whose lower end is connected to the lower end of the guide block 13 via a ratchet mechanism 14. The ratchet mechanism 14 includes fixed side ratchet teeth 14a fixed to the lower surface of the guide block 13, and a spring adjustment shaft 1.
As clearly shown in FIG. By rotating the lower end head 15a, the spring pressure of the spiral spring 12 can be increased or decreased by 60 degrees.

As clearly shown in FIG. 4, the connector 5 has a substantially L-shaped rotation hole 17 in the center that rotatably fits into a support shaft 18 protruding from the side surface of the guide block 13. Along with this, there is an engaging protrusion 1 on the upper and lower surfaces of the tip.
An L-shaped latch 19 having an L-shaped latch 19 and a screw 20 are fastened to the lower edge of the elevator window 2, and an engagement protrusion 19a of the latch 19 is fixed to the longitudinal engagement elongated hole 21 in the center.
The guide pin 23 is constructed of a receiver 22 that can be freely engaged and detached from the guide block 13, and a guide pin 23 that projects below the support shaft 18 on the side surface of the guide block 13 and that fits into the rotation hole 17.

FIG. 5 shows a horizontal sectional view of a unit window for a vehicle, and the window frame 1 consists of the above-mentioned vertical frame member 7 and a window frame body 25 made of an extruded aluminum material to which the vertical frame member 7 is bolted. The guide wall portion 25a of the window frame body 25 and the frame body 7a of the vertical frame member 7 are connected to the elevator window 2.
A vertical passageway is formed. Also, the vertical frame member 7
is covered by an inside frame 26 that is fitted and fixed into the window frame main body 25 from the inside of the car, so that the balancer mechanism 3 and the connecting fitting 5 are not visible from inside the car. In addition, in FIG. 5, 27 is a guide path for a sunshade roll curtain, 28 is a frame on the outside of the vehicle, 29 is a vehicle outer panel, and 30 is a vehicle inner panel.

In the above configuration, when the balancer mechanism 3 is attached to the elevator window 2, the latch 19 is tilted to the same height as the receiver 22 from the state shown in FIG. 1 to the imaginary line in FIG. After bringing into position,
Rotate the latch 19 around the support shaft 18, and
As shown by the solid line in the figure, the engagement protrusion 19a may be engaged with the engagement elongated hole 21. At this time, the latch 19
is always urged upward by the spiral spring 12 of the balancer mechanism 3, so the latch 19
will not be removed from the money receiver 22.

When the balancer mechanism 3 is attached to the elevator window 2, the spiral spring 1 of the balancer mechanism 3
Since the nut member 10 is pressed against the torsion plate 11 by the urging force of 2, when the elevating window 2 is stopped at an arbitrary height position, the nut member 10 and the torsion plate 11 are frictionally engaged, and the elevating and lowering is stopped.
