  • Patent number: 9447623
    Abstract: A door checker includes a stopper provided to a tip portion of a check lever and defining a door opening limit by engaging with stopper surfaces provided to an outer surface of a peripheral edge of a through-hole in a support body. The stopper is formed from paired first stopper portions engageable with paired first stopper surfaces arranged side-by-side with the through-hole therebetween, and paired second stopper portions engageable with paired second stopper surfaces. The first stopper portions are formed from metal-made protrusions integrally projecting from opposite sides of a tip portion of a lever core plate, and projecting from an outer surface of a synthetic resin-made covering portion. The second stopper portions are formed from synthetic resin-made portions of the outer surface located between the first stopper portions and swollen on opposite sides in a direction orthogonal to an arrangement direction of the first stopper portions.
