Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for supporting a synthetic resin support of a floor type shift lever of a so-called automatic vehicle.

[0002]

2. Description of the Related Art Conventionally, as this type of support supporting structure, there is a structure shown in FIG. 4, for example. That is,
In this conventional structure, the synthetic resin support 11e of the shift lever 1e is inserted into the lever bracket 2e, and the holes 25 and 25 formed in the lever bracket 2e and the through hole 19 formed in the support 11e. Bolt to 9
These are intended to be connected by inserting. With this structure, it is possible to swing the shift lever 1e using the bolt 9 as a pivot.

[0003]

However, in the above-mentioned conventional structure, the lever bracket 2e has the support 11e.
Since the bolt 9 is used as a means for connecting the
The bolt 9 itself not only causes an increase in the number of parts as a whole, but also requires a washer 90 and a nut 91 as other parts for tightening the bolt 9. Also,
It is necessary to perform screw tightening work for each of these parts, and the number of assembling steps also increases. Therefore, conventionally, the cost of parts and the cost of assembly work have increased.

Incidentally, conventionally, a pin made of metal or synthetic resin, for example, is penetrated from one side of the lever bracket to the support without using a bolt, and the tip of this pin is bored on the opposite side of the lever bracket. There are some parts that do not require parts such as nuts or screws to be tightened by pressing them into the holes and fixing them. However, even with such means, it is necessary to separately manufacture and prepare a special pin. In addition, work steps such as inserting this pin into the hole of the support or lever bracket are also required. Therefore, there is still room for improvement in terms of manufacturing cost.

The present invention has been devised under such circumstances, and the shift lever is composed by a structure that does not require separate parts such as bolts and pins and has a simple assembling work. The problem is to properly connect and support the resin support to the lever bracket.

[0006]

In order to solve the above problems, the present invention takes the following technical means.

That is, according to the invention of the present application, flat support projections serving as rotation fulcrums of the shift lever are integrally formed on both sides of the synthetic resin support of the shift lever, and the support is inserted therein. A pair of side wall portions of the lever bracket which face each other are provided with a notch groove for inserting and guiding the support projection of the support into a support hole formed in each of the pair of side wall portions, and , The cutout groove is outside the angular region in which the end portion of the support protrusion rotates inside the support hole when the support protrusion is inserted into the support hole and the shift lever is oscillated within a certain angle range. It is characterized by being placed in.

[0008]

In the present invention, the flat-shaped support projections provided on both side surfaces of the synthetic resin support of the shift lever are supported by the lever bracket from the positions where the notches formed in the lever bracket are formed. The support can be inserted into the hole, and the support can be connected to and supported by the lever bracket. Further, in such a connected support state, when the shift lever is oscillated within a constant angle range, the support protrusion inserted into the support hole rotates at a constant angle. Since the groove is provided outside the angular region in which the end of the support protrusion rotates, there is no problem that the end of the support protrusion fits into the cutout groove when the shift lever is operated. Does not happen. Therefore, the support protrusion of the support is properly inserted and held in the support hole of the lever bracket even if the notch groove is left open without providing a means for closing the notch groove with an appropriate member. It is possible to allow the shift lever to perform an appropriate swing operation with the support protrusion as a fulcrum.

As described above, according to the present invention, by inserting the flat support protrusion integrally formed with the synthetic resin support into the support hole of the lever bracket, the synthetic resin support of the shift lever is properly attached to the lever bracket. It can be connected and supported. Therefore, unlike the prior art, it is not necessary to use separate parts such as bolts and pins as means for connecting and supporting the shift lever support to the lever bracket. As a result, the total number of parts is reduced,
In addition, it is possible to eliminate the work process of inserting another component such as a bolt or a pin into the support or the lever bracket, simplify the series of assembling work, and reduce the manufacturing cost.

Is formed in an arc shape centered on the axis L. These support protrusions 13 and 13 are the support 11
The support 11 is integrally molded at the time of resin molding.

A detent pin 3 is provided on the side surface of the support 11 so as to project therefrom. The detent pin 3 is configured to perform a descending operation (or an ascending operation) when an operation button (not shown) of a grip portion attached to the upper portion of the shaft 10 is pressed, and the lever bracket. The shift lever 1 is locked by engaging with the recessed groove portion 29 of the detent plate portion 28 provided on the No. 2 to prevent an inadvertent shift operation.

The lever bracket 2 has a top opening-like form in which a space 20 for accommodating the support 11 of the shift lever 1 is formed. Also, on one of the lower front portion or the lower rear portion of the lever bracket 2,
An opening 21 for inserting the support 11 into the lever bracket 2 from the lower side of the lever bracket 2 is also formed.

Support holes 23, 23 for fitting and holding the support protrusions 13, 13 of the support 11 are respectively formed in the lower portions of the pair of left and right side wall portions 22, 22 of the lever bracket 2.
Are provided coaxially. In addition, these support holes 23,
Notch grooves 24, 24 are provided in a row at 23, respectively. The width S of each of the cutout grooves 24 is formed to be slightly larger than the width S1 of each of the support projections 13 of the support 11, and each support projection 13 is formed from the location of the cutout groove 24 to each of the support holes 2 described above.
It is set so that it can be inserted and guided into the inside. In addition,
The locations where these notch grooves 24 are formed are as described below.
The support protrusions 13 of the support 11 are connected to the cutout grooves 24.
It is designed so that it will not pass through and fall out of the lever bracket 2.

In order to assemble the support 11 of the shift lever 1 and the lever bracket 2 described above, first, with the upper side of the support 11 facing upward, the support 11 is opened from the opening 21 of the lever bracket 2 to the lever bracket 2.
