Abstract
In a power transfer device for four-wheel drive including a differential arranged to split the driving torque from a power transmission into two torque delivery paths, a first output shaft assembly in drive connection to the differential to transfer the split driving torque to front or rear-wheel drive axles and a second output shaft assembly in drive connection to the differential to transfer the split driving torque to rear or front-wheel drive axles, one of the output shaft assemblies being composed of a pair of split shafts, a shift mechanism includes a clutch sleeve slidably mounted on one of the split shafts for rotation therewith and shiftable between a first position where it is engaged with the other split shaft and a second position where it is disengaged from the other split shaft, a manually operated plug member rotatably coupled within a corresponding bore in the peripheral wall of a housing of the transfer device, and a fastening bolt threaded into the peripheral wall of the housing to fasten the plug member to the housing at a rotated position, the plug member having an inner end portion integrally provided with an eccentric cam pin which is engaged with an annular g…
