Abstract
To incorporate a viscous coupling type power transmission apparatus for a four-wheel driven automotive vehicle with an antiskid braking system, viscous torque transmission from a first rotary transmission shaft (coupled to the front wheel shaft) to a second rotary transmission shaft (coupled to the rear wheel shaft) is intermitted by a clutch mechanism provided for the power transmission apparatus whenever a foot brake is applied. That is, when a foot brake pressure is applied to the brake member of the power transmission apparatus, the clutch mechanism is disengaged via a cam ring to decouple the first rotary transmission shaft from the second rotary transmission shaft.
