FIGS. 9A and 9B are reprints of FIGS. 1 and 3 of Patent Document 1. FIG.
The operating lever device for a traveling vehicle of Patent Document 1 is provided with an operating lever 4 that can be rotated in the front-rear direction by a hand, a push button 38 disposed above the operating lever 4, and a lower side of the push button 38. A shift up button 44 and a shift down button 45 and an interlocking rod 36 inserted into the operation lever 4 are provided. The shift-up button 44 and the shift-down button 45 are used for shifting the traveling speed, and are used to select an eight-speed speed. The control lever is connected to the control mechanism through the electric wire 201 (new reference numeral) in the operation lever 4. Connected switch.
Thus, the wiring structure is simplified by placing the electric wire 201 directly below the upshift button 44 and the downshift button 45, specifically, along the side of the interlocking rod 36 (in the vehicle width direction).

However, in the operation lever device of Patent Document 1, as shown in FIG. 9A, the operation lever 4 has a dimension Wc in the vehicle width direction that is larger than the dimension Lf in the front-rear direction. The degree of freedom of arrangement of the operation lever device (select lever device) with respect to the room width is low. For example, if it is arranged in the vicinity of the steering handle, the degree of freedom in designing the instrument panel is reduced.
Recently, there are an increasing number of vehicles in which a monitor of a navigation device is attached to an instrument panel. In particular, in the case of a small vehicle, the design of the instrument panel, for example, the position of the monitor, the monitor, is smaller than that of a normal vehicle. The degree of freedom of design such as the size and the container tends to be low. For this reason, it has been desired to reduce the dimension of the select lever device in the vehicle width direction.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a select lever device for an automatic transmission that solves the problem that the dimension of the select lever device in the vehicle width direction is increased and is reduced in thickness.

The select lever 22 also has a longer diameter De (De> de) that is a dimension in the vehicle longitudinal direction (direction of the arrow 27) than a minor diameter de that is a dimension in the vehicle width direction (the direction of the arrow 17). It is set. W is the width of the select lever 22 and is equal to the minor axis de (de = W).

The operation of the automatic transmission select lever device described above will now be described.
The select lever 22 shown in FIG. 8 has a larger longitudinal axis De (De> de) in the vehicle longitudinal direction than the minor axis de in the vehicle width direction, so that the lever corresponding to the selector lever operation in the longitudinal direction (direction of arrow 27). There is an advantage that the width W of the select lever 22 can be reduced while maintaining rigidity, and as a result, the dimension in the vehicle width direction of the select lever device 15 can be reduced.
As a result, it is possible to increase the degree of freedom of arrangement of the select lever device 15 of a small car that has no margin in the vehicle width direction as compared to a normal car, and to increase the degree of freedom of design of the instrument panel 13 (see FIG. 1). be able to.

  Further, since the lock pin rod 124 and the push button switch electric wire 133 are disposed in the front and rear in the inner pipe 122 of the select lever 22, the width W of the select lever 22 is set within the outer diameter Dr of the lock pin rod 124. The thickness t1 of the pipe 122 (see FIG. 6) and the thickness of the outer pipe 123 need only be added to each other, and the width W of the select lever 22 can be further reduced. As a result, the vehicle of the select lever device 15 can be reduced. There is an advantage that the width dimension can be reduced.

  The select lever device for an automatic transmission according to the present invention is applied to a four-wheeled vehicle in the embodiment, but can also be applied to a three-wheeled vehicle and can be applied to a general vehicle.

  The select lever device of the automatic transmission of the present invention is suitable for a four-wheeled vehicle.
