A double-sided reclining apparatus, comprising a first reclining device equipped with a reclining-lever handle and a second reclining device. Each reclining device includes a base to be fixedly connected to a seat cushion and an arm adapted to be fixedly connected to a seat back and rotatably supported on the base through a pivot shaft. The arm has a first toothed portion. A cam and a toothed cam follower are in cam-connection with each other. The toothed cam follower has a second toothed portion meshable with and unmeshable from said first toothed portion, said cam and said toothed cam follower are cooperative with each other for causing meshed-engagement of the second toothed portion with the first toothed portion through a rotary motion of the cam in a first rotational direction to lock the reclining device, and for causing disengagement of the second toothed portion from the first toothed portion through a rotary motion of the cam in a second rotational direction opposed to the first rotational direction to unlock the reclining device. The cam included in the outside reclining device is mechanically linked to the cam included in the second reclining device through a connecting pipe. A cam profile of the cam included in the second reclining device is formed with at least one raised portion.
