DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a partially sectional front view of the first embodiment, and FIG.
, And FIG. 3 also shows a partial cross section of the side surface, 1 is an operation lever, 2 is a stopper for guiding the movement of the operation lever as shown in FIGS. 1 and 3 above, 3 is a stopper pin and 4 is a hole. A bracket 5 is provided near the stopper 2, and a projection 6 is formed on the upper surface of the bracket 5.
Eye 8 is fixed.

The spring 7 has a planar form as shown in FIG. 2, and a first curved portion 9 is formed between the eyeball 8 and both ends, one of which approaches the other. An outwardly projecting second curved portion 10 is formed on the side of the curved portion 9 near the end portion side from the curved portion 9, and R of the curved portion 10 is set to be substantially the same as the diameter of the operation lever 1. ing. As shown in FIGS. 1 and 2, a state in which a part of the lower part of the operation lever 1 is accommodated in the curved portion 10 is an H (hold) position.

The first embodiment is constructed as described above. The operation of the first embodiment will be described with reference to FIG. 4. In FIG. 4, the position of the spring 7 shown by the solid line is H. For example, in order to move to the U (up) and D (down) positions, the operating lever 1 may be moved as it is as shown by the reciprocating arrow A in FIG. Can be For example, if the user once moves to the U position and releases his hand, the spring 7
The operation lever 1 returns to the H (hold) position by the force of.

In order to bring the operation lever 1 to the position of N (neutral), the operation lever 1 may be moved in the direction of arrow B in FIG. In this case, the operating force is obtained because the spring 7 is expanded, and the operating lever 1 returns to the H position when the hand is released. To bring it to the R (reverse) position, the operation lever 1 may be moved as shown by the arrow C in FIG. In this case, an operating force is obtained by the expansion and bending of the spring 7, and when the hand is released as it is at the position R, the operation lever 1 is moved to H by the reaction.
It returns to the position of.

The positions of the spring 7 and the operating lever 1 in each of the above-mentioned states are indicated by two-dot chain lines in FIG. In this case, the relationship between the stroke and the operation force is a linear relationship as shown in the table of FIG. The shift pattern based on the position of the shift lever at that time is shown in FIG.
It is as shown in.

In the first embodiment, the spring 7 is provided in a horizontal direction, that is, at a right angle to the operation lever. However, the present invention is not limited to this. This is shown in the second embodiment shown in FIG. 7, FIG. 8, and FIG.

In these figures, the same reference numerals as those in the first embodiment denote the same members as those in the first embodiment.
In the second embodiment, as shown in FIG.
Is fixed to a projection 22 provided inside the frame 21, one end of the stopper pin 3 is extended, and this is accommodated in the spring 7.

Even with such a configuration, basically the same operation and effects as those of the first embodiment can be obtained.

The above is an embodiment in which the stroke and the operating force have a linear relationship. However, in the present invention, the operating force of the operating lever is changed in two steps only by providing auxiliary fulcrums on both outer sides of the spring. it can.

That is, as shown in FIG. 10, when an auxiliary fulcrum 31 is provided outside the curved portion 9 of the spring 7 and an auxiliary fulcrum 32 is provided outside the auxiliary fulcrum 31 in FIG.
As is clear from comparison with
When the operating lever 1 is moved in the direction of the arrow D in the drawing to move the operating lever 1 to the (up) position, the position of the eyeball 8, that is, the position of the fulcrum E initially becomes the rotation fulcrum. However, if the user continues to move, the position of the auxiliary fulcrum 31, that is, the position of the fulcrum F, becomes the rotation fulcrum. In this case, since the position of the rotation fulcrum has changed in two stages,
The operating force has also changed in two stages accordingly. Of course, if the hand is released, the operation lever 1 returns to the H (hold) position. In the other positions, D (down), N (neutral), and R (reverse), the operation lever can be similarly moved by a two-step operation force. FIG. 11 is a graph showing the relationship between the stroke and the operating force in these cases.

As described above, the operation lever can be easily operated by the two-stage operation force, and in this case, a feeling that the shift operation is surely performed can be obtained. In this case, if a rubber mold or a resin roller is used for the auxiliary fulcrum, the hitting sound can be prevented.

In any of the above-mentioned embodiments, if a resin roller is provided at the load point of the spring, it is possible to prevent hitting and abrasion.

[0021]

According to the invention, D (down), U
The spring force acts on the moving member in any of the (up), R (reverse), and N (neutral) positions, so that when the hand is released, the lever returns to the H (hold) position by the force of the spring. . Therefore, the driver only has to operate assuming that the shift operation lever is always at the H (hold) position.

Moreover, since the operating force is almost proportional to the stroke, the operating feeling is good.

From a structural point of view, since all operating forces are realized by one spring, the structure is simple and compact.

Further, the two-step operation force can be realized only by making a very simple modification.
