Abstract
A shift lever apparatus combines an automatic transmission mode and a manual transmission mode. An end portion of a position pin engages with a guide lever. The guide lever comprises a guide hole. When the guide lever is swingably supported by a transverse shaft and a shift lever is moved into the manual transmission mode, an upside edge of the guide hole stops and lowers the end portion of the position pin. Thus, the position pin can swing between an R range and an L range.
Claims11
A shift lever apparatus for an automatic transmission, comprising:
- a base bracket adapted to be fixed to a vehicle body;
- a shift lever comprising a shift lever main body supported on the base bracket through a transverse shaft for allowing the shift lever main body to swing in a front and rear direction, and so arranged as to allow the shift lever main body to move between an automatic transmission (A/T) mode shift slot and a manual transmission (M/T) mode shift slot,
- a position pin comprising first and second end portions for engaging with detent notch portions formed in first and second side wall portions of the base bracket when the shift lever main body is in the A/T mode shift slot,
- a push button mounted on an upper portion of the shift lever main body, and
- a projecting portion formed in the shift lever main body;
- a selector lever swingably mounted on the transverse shaft, said selector lever comprising an opening for receiving the projecting portion so as to move together with the shift lever main body when the shift lever main body is in the A/T mode shift slot and for disengaging from the projecting portion so as to allow the shift lever main body to swing in the front and rear direction and to turn on electric switches when the shift lever main body is in the M/T mode shift slot;
- and
- a guide lever, swingably mounted on the transverse shaft, comprising a guide hole for engaging with the first end portion of the position pin, said guide hole comprising an upside edge for limiting upward movement of the first end portion of the position pin and thereby causing the position pin to incline so that the second end portion descends to a lower position relative to the second side wall to allow the position pin to swing between an R range and an L range in detent notch portions when the shift lever is changed into the M/T mode shift slot.

A shift lever apparatus for an automatic transmission, comprising:
- a base bracket member adapted to be fixed to a vehicle body, the base bracket member comprising a top portion formed with an automatic transmission mode shift slot and a manual transmission mode shift slot which are connected by a switching slot, and first and second side wall portions each formed with a detent notch portion;
- a shift lever assembly comprising a shift lever main body which is supported on the base bracket member through a transverse shaft for allowing the shift lever main body to swing in a front and rear direction, and which is formed with a projecting portion, and a base member which is swingably mounted on the transverse shaft for allowing the main body to swing in the front and rear direction, the main body being swingably mounted on the base member through a longitudinal shaft for allowing the main body to swing in a left and right direction and thereby to move between the automatic transmission mode shift slot and the manual transmission mode shift slot through the switching slot, the shift lever assembly further comprising a position pin having first and second end portions for engaging with the detent notch portions formed in the first and second side wall portions of the base bracket member when the shift lever main body is in the automatic transmission mode shift slot, the shift lever assembly further comprising a push button mounted on an upper portion of the shift lever main body, for moving the position pin upward and downward, and
- a selector lever swingably mounted on the transverse shaft, and formed with an opening for receiving the projecting portion of the shift lever main body so as to move together with the shift lever main body when the shift lever main body is in the automatic transmission mode shift slot and for disengaging from the projecting portion so as to allow the shift lever main body to swing in the front and rear direction when the shift lever main body is in the manual transmission mode shift slot;
- and
- a guide lever swingably mounted on the transverse shaft, and formed with a guide hole for engaging with the first end portion of the position pin, said guide hole having an upside edge for limiting upward movement of the first end portion of the position pin and thereby lowering the second end portion of the position pin when the shift lever main body is moved into the manual transmission mode shift slot.
