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.

A door hinge is provided for a side-door of a vehicle whereby an impact applied to the side door in a direction transverse to the vehicle is absorbed at a connecting portion for connecting the side door to the body of the vehicle. The door hinge is comprised of a female and a male, and a connecting portion is provided uprightly on the male. Bearing portions are provided uprightly on the female, and the connecting portion and the bearing portions rotate relatively to each other with a shaft as a center of rotation. The connecting portion of the male is curved in such a manner as to protrude in the forward direction of the vehicle, and a point of application of a load and a support point in the male are offset from each other in the longitudinal direction of the vehicle. In a case where an impact load is applied to the side door from its outer side in the transverse direction of the vehicle, the connecting portion of the male becomes further curved in such a manner as to protrude further in the forward direction of the vehicle.
