The shaft (20) of the metal roller (22) is slidably fitted into this long hole, and the shaft (20) is moved to the second position by a compression spring or the like.
You may make it urge toward the side piece (8) side.

〔The invention's effect〕

Since the present invention is configured as described above, the following effects can be achieved.

(A) Since two resin rollers and one metal roller roll along the inner surfaces of the first side piece and the second side piece of the guide rail, there is almost no sliding resistance and light force is exerted. The window glass can be moved up and down.

(B) Since the metal roller can appear and disappear with respect to the carrier plate, even if there is some deviation in the distance between the first side piece and the second side piece, the metal roller appears and disappears. It can be absorbed and there is no risk of sticking.

(C) The reaction force when the durable metal roller is pressed against the second side piece is divided into two parts, and the two resin rollers weaker in strength than the metal roller receive the reaction force. In addition, it is less likely that the movement of the window glass will be hard and unpleasant metal noise will be generated, unlike the conventional one in which all the rollers are made of metal.

That is, the second side piece of the guide rail comes into contact with the metal roller, but the first side piece facing the second side piece comes into contact with the two resin rollers having appropriate elasticity. The metal hard contact feeling with the roller can be absorbed by the soft contact between the first side piece and the resin roller, so the moving feeling of the window glass becomes soft and the metal noise when the metal roller rolls. Is also well absorbed.

(D) Since the resin rollers and the metal rollers are constantly in pressure contact with the first side piece and the second side piece of the guide rail by the urging means, the rollers move in the guide rail. The window glass does not rattle, and when an impact load is applied to the window glass, the carrier plate elastically tilts with respect to the guide rail as described above, so that the impact can be absorbed and alleviated. You can
Less likely to be damaged.

(E) The risk of rust is only one metal roller, and even if rust occurs on the rolling surface of this metal roller,
Since the adverse effect due to this can be absorbed by the two resin rollers, it is possible to smoothly guide the window glass for a long time as compared with the case where all the rollers are made of metal.

(F) Since only one expensive metal roller is used,
It can be manufactured at a lower cost than when all the rollers are made of metal.
