Claim:
A reclining apparatus for use with a vehicular seat having a seat cushion and a seat back rotatable relative thereto, comprising: a first angle adjusting mechanism provided at a first side of the seat in a seat width direction; a second angle adjusting mechanism provided at a second side of the seat in the seat width direction, the first angle adjusting mechanism and the second angle adjusting mechanism adjusting an angle of a second frame relative to a first frame, the first frame forming a main structure of a first portion of the seat, and the second frame forming a main structure of a second portion of the seat; a connecting shaft extending in the seat width direction and being eccentric to a center of a rotating shaft of each of the first angle adjusting mechanism and the second angle adjusting mechanism; a first actuating mechanism including a first rotating shaft side rotating member rotating relative to the center of the rotating shaft of the first angle adjusting mechanism, a first connecting shaft side rotating member that rotates integrally with a first end portion of the connecting shaft, and a first transmitting means for transmitting the rotation between the first rotating shaft side rotating member and the first connecting shaft side rotating member; a second actuating mechanism including a second rotating shaft side rotating member rotating relative to the center of the rotating shaft of the second angle adjusting mechanism, a second connecting shaft side rotating member that rotates integrally with a second end portion of the connecting shaft, and a second transmitting means for transmitting the rotation between the second rotating shaft side rotating member and the second connecting shaft side rotating member; an electric drive source supplying a drive force to the first actuating mechanism for driving thereof, the connecting shaft transmitting the drive force from the first actuating mechanism to the second actuating mechanism; a first housing including a first closed space accommodating the first actuating mechanism completely, the first end portion of the connecting shaft being inserted into the first housing; and a second housing including a second closed space accommodating the second actuating mechanism completely, the second end portion of the connecting shaft being inserted into the second housing.
