PURPOSE:To improve the operation efficiency, by performing the speed change operation and switching for two-wheel drive and four-wheel drive simultaneously with one operation lever, in the car speed change gear which switches low-speed and high-output four-wheel drive and four-wheel drive of the efficient operation in the high speed region. CONSTITUTION:The shift rail to operate subspeed change gear S, operation rail 50 provided with three shift positions for two-wheel drive, high-speed four-wheel drive, and low-speed four-wheel drive on one straight line, and a fixed rail are arranged closely in parallel. Arm 57 is so provided among these three rails so that arm 57 and the shift rail may be one body and arm 57 may be fitted slidably to other two rails, and shift fork 59 to operate clutch device N between rail 50 and the fixed rail is fitted slidably. As a result, the speed change operation and the switching operation for two-wheel drive and four-wheel drive are performed simultaneously with one operation lever 54, so that the operation efficiency can be improved. |
