First, second and third pivotal levers are interconnected through a link mechanism in order to operate a latch mechanism which includes a latch plate and a pawl plate. When the first lever assumes its latch position and the third lever assumes its first angular position, pivoting of the second lever toward its second angular position induces a pivoting movement of the first lever toward its unlatch position thereby to release the latched condition of the latch mechanism. When the first lever assumes its latch position and the third lever assumes either its second or third angular position, pivoting of the second lever toward its second angular position has no effect of the first lever thereby holding the latch mechanism in the latched condition. When the first lever assumes its unlatch position, pivoting of the second lever toward its second angular position has substantially no effect on the first lever irrespective of angular position which the third lever assumes and the third lever is prevented from assuming its third angular position.
