Abstract:
1. A saddle type vehicle with a forward/reverse travel changeover mechanism in which a driving wheel and an engine for driving said driving wheel through a sprocket are mounted on a vehicle body frame and a seat for a driver is disposed above said engine, comprising: a main transmission for changing the speed of power from said engine and transmitting the power of the changed speed to said driving wheel; a forward/reverse travel changeover mechanism operatively connected to said main transmission for converting the direction of the power from said main transmission and transmitting the power of the changed direction; and said forward/reverse travel changeover mechanism includes: a projection formed by causing an output power shaft for outputting the power from said main transmission to project to the outside of a main transmission case of said engine; a sun gear provided on said projection for rotating integrally with said projection; a carrier rotatably supported relative to said sun gear around said projection; a planetary gear self-rotatably supported on said carrier and rotatably mating with said sun gear; an internal gear rotatably supported relative to said projection around said projection and mating with said planetary gear; an output sprocket rotatably supported integrally with said internal gear by said internal gear, which rotates around said projection adjacent to said main transmission with respect to said sun gear; and a shifter for selectively changing over the position of said carrier and said internal gear between a forward travel position at which said carrier and said internal gear are connected against relative rotation and a reverse travel position for preventing rotation of said carrier around said projection; said forward/reverse travel changeover mechanism being disposed outside said main transmission case.
