Description

  The present invention relates to a shift lever device that operates an automatic transmission of an automobile, and more particularly to a type that is fixed to an instrument panel side of a vehicle body.

  Although the number of vehicles that provide shift lever devices on an instrument panel is increasing, space restrictions are large because an air conditioner, audio equipment, and the like are provided on the instrument panel. Therefore, it is well known that downsizing of the shift lever device is desired. However, the shift lever device has requirements for rigidity and strength such that it does not break even when a predetermined load is applied to the knob, and there are also requirements for the amount of movement of the shift cable connected to the transmission and its pushing and pulling force. It has been said that miniaturization is difficult.

Therefore, Patent Document 1 below discloses a shift lever device that includes an automatic transmission operating force support device and a transmission switching device, which enables shifting of the transmission with an extremely light operating force. A structure is disclosed.

The end portions of the pair are rotatably supported by shaft holes provided in the pair of shells, and one end portion penetrates the bearing hole and protrudes to the outside of the shell. The shift lever device is characterized in that a shift lever that locks one end of a shift cable connected to the transmission is fixed.

According to the present invention, the gap between the case housing and the shift lever is minimized by configuring the shift housing to sandwich the shift lever with a substantially U-shaped shell that is divided into left and right parts. The case housing can be greatly reduced in size. In addition, since the case housing is provided with mounting holes on the vehicle body so as to sandwich the bearing portion of the shift lever, it is possible to increase the support rigidity of the shift lever and the strength of the case housing, Sufficient rigidity and strength can be secured. Furthermore, one end of the shift shaft fixed orthogonally to the shift lever penetrates the case housing and protrudes outward, and the shift lever that locks the shift cable connected to the transmission is connected to the protruding end. Since it is fixed, there is no need to provide a space for locking the shift cable in the case housing, and the effect of reducing the size of the case housing can be obtained.

  In the shift lever device of the present invention, the shift lever is pivotally sandwiched between a case housing divided into left and right, and a mounting hole on the vehicle body side is provided in the case housing so as to sandwich the shift shaft.

A small-diameter shaft support 4 is provided in the part. One end of the shaft support 4 is integrally formed with an oval cross-sectional portion 4a and a threaded portion 4b. After a shift lever 5 having an oval fitting hole 5a is press-fitted into the oval surface 4a, a nut 6 is used. It is concluded. The shift lever 2 is formed with axially elongated holes 7 and 7 facing each other in the diametrical direction, and a compression rod 32 in which a position pin 8 passing through the elongated holes 7 and 7 is inserted perpendicularly and the compression rod 32 is always provided. A spring (not shown) to be pushed up is inserted. A shift knob 10 having a knob button 9 that pushes the compression rod downward is attached to the upper end of the shift lever 2.

  A case housing 1 for pivotally supporting the shift lever 2 includes shells 11 and 12 such as aluminum die castings having a substantially U-shape divided into left and right parts with the shift lever 2 as a center. A shaft hole 13 serving as a bearing portion for inserting the shaft support portion 4 and rotatably supporting the shaft support portion 4 and a detent groove 14 with which the position pin 8 engages are formed. The shells 11 and 12 are U-shaped when viewed from above, and the bolts 31 are inserted into the bolt insertion holes 16 a formed in the overlapping surface 15 of one shell 11, and the overlapping surface 15 of the other shell. Fastened to the screw hole 16b. A space formed when the left and right are overlapped becomes a shift groove 17 in which the shift lever 2 rotates.

  As shown in FIG. 5, the assembly is performed by fixing the shaft 3 of the pair of shells 11 and 12 to the shift shaft in a state where the shift shaft 3 is fixed and the compression rod 32 and the position pin 8 are assembled to the shift lever 2. The shells 11 and 12 are overlapped so that the position pin 8 is inserted into the detent groove 14. A resin bush 33 is inserted between the shaft support 4 and the shaft hole 13.
