[Prior Art] Transmissions for converting and extracting the driving force of an internal combustion engine include gear-type transmissions and belt-type transmissions, and gear-type transmissions with less transmission loss of driving force are often used. has been done. A gear-type transmission converts and extracts the driving force of an internal combustion engine according to the gear ratio of the switched gear train by switching the meshing state to one of a plurality of gear trains. Further, the transmission is provided with a switching mechanism for switching the meshing state of the transmission gear train, and is also provided with a shift lever for operating this switching mechanism.

There are various types of shift levers for transmissions, such as a direct type that directly shifts the yoke of the transmission, a direct type with a remote control shaft that shifts the yoke by providing a remote control shaft in the transmission, a cable type, and a rod type.

An example of a shift lever for a direct type transmission is shown in FIG. In the figure, 102
1 is a transmission, 136 is a shift shaft group, and 146 is a shift lever. When the shift lever 146 is selectively operated, a shift and select lever 148 provided on the shift lever 146 is selectively engaged with one of the shift yokes 138 provided on the shift shaft group 136. Next, when the shift lever 146 is operated to shift, any one of the shift shaft groups 136 selectively engaged by the shift and select lever 146 is moved in the axial direction, and the shift gear trains 114 of the plurality of transmission gear trains 114 provided in the transmission 102 are moved. Switch the meshing state to either one. As described above, as a device for directly operating one of the shift shaft groups by the shift lever of the transmission, the method described in Utility Model Publication No. 1-3209
This has already been disclosed in Publication No. 9.

Further, as a shift lever for a direct type transmission with a remote control shaft, there is one shown in FIG. In the figure, 202 is a transmission, 236 is a shift shaft group, 240 is a remote control shaft, and 246 is a shift lever. When the shift lever 246 is selectively operated, a shift and select lever 248 provided on the remote control shaft 240 is selectively engaged with one of the shift yoke groups 238 provided on the shift shaft group 236, respectively. Next, when the shift lever 246 is operated to shift, the shift and select lever 248 is selectively engaged with the shift shaft group 2 via the remote control shaft 240.
38 is moved in the axial direction to switch the meshing state to any one of the plurality of speed change gear trains 214 provided in the transmission 202. As described above, a system for semi-directly operating a group of shift shafts using a shift lever of a transmission via a remote control shaft has already been disclosed in Japanese Utility Model Publication No. 61-37060.

[0006]

In the conventional shift lever of a transmission, the shift lever housing was directly attached to the transmission case.

[0007] For this reason, the mounting position of the shift lever is restricted, and vibrations on the transmission case side are transmitted to the body side, which is disadvantageous in practical terms.

[0008] Furthermore, if the shift lever is too far away from the transmission case, there is an inconvenience that the transmission side and the shift shaft may become distorted.

[0009]

[Means for Solving the Problems] In order to eliminate such inconveniences, the present invention provides a transmission that is operated to change gears via a remote control shaft operated by a shift/select operation of a shift lever attached to a shift lever housing. A cross joint is provided in the middle of the remote control shaft, one end of a communication member is fixed to the shift lever housing, and the other end of the communication member is attached to the transmission side via a first vibration isolating member, and the shift lever The present invention is characterized in that the housing is attached to the body side via the second vibration isolating member.

0010

[Operation] According to the invention as described above, when shifting the transmission, the remote control shaft is operated by the shift/select operation of the shift lever, and the transmission is shifted by the operation of the remote control shaft. At this time, the first and second vibration members prevent vibrations from the transmission side from being transmitted to the body side, and the cross joint in the middle of the remote control shaft prevents the transmission side and the shift lever from getting twisted. There is.
