Patent ID: 7004268

Claim:
A vehicle, comprising: a prime mover; a pair of drive wheels; a pair of transmissions for transmitting power of said prime mover to said respective drive wheels, each of said transmissions including an output control device for controlling output direction and speed of said corresponding transmission; a traveling operation device for setting a traveling speed of said vehicle and selecting a traveling direction of said vehicle between forward and rearward directions; a steering operation device for turning said vehicle leftward or rightward; an operational relay member interlockingly interposed between said traveling operation device and said output control devices of said pair of transmissions, wherein said operational relay member is moved in a first direction by operating said traveling operation device so as to set equal output direction and speed of both of said transmissions; and an actuator interlockingly connected to said operational relay member, wherein said operational relay member is moved in a second direction by actuation of said actuator so as to set differential output directions and speeds of both of said transmissions, and wherein the actuation direction of said actuator is decided depending upon whether said traveling operation device is operated for forwarding traveling or backward traveling and depending upon whether said steering operation device is operated for leftward turning or rightward turning.
