An improved method for manufacturing a lever for an automotive door checking device and the lever produced by the method. According to the invention, the mold employed for the molding of the sliding part of the lever has a gate at one of the two longitudinal ends of the cavity wall so that the molten resin containing reinforcing fibers flows in and fills up the cavity along the longitudinally extending direction corresponding to the sliding direction of the sliding part. As a result, the reinforcing fibers embedded in the sliding part are one-dimentionally oriented to the sliding direction thereof, which provides anti-wearing property, durability and good sliding characteristics of the lever.
