A dual lock seat reclining mechanism includes left and right devices and a connection member connecting the left and right devices. Each device includes a base member to be fixed to a seat cushion, a swing tooth plate adapted to be fixed to a seat back and swingably mounted on the base plate through a center shaft, and a look tooth member having an external toothed portion for engaging with an internally toothed portion of the swing tooth plate. An operation member or lever is swingable between the base member and the swing tooth member, for moving the look tooth member toward and away from the internal toothed portion of the swing tooth plate for locking and unlocking. The operation member has a pin slidably received in an elongate arc hole of the base plate. A link has an outer bent portion engaged with the pin in the elongate hole, and an inner portion connected with one end of the connection member for transmission of rotation.
