Patent ID: 7861372

Claim:
An automobile door checker comprising: a case secured to one of an automobile body and a door pivotally supported on the automobile body, a check plate that runs movably through the case and is coupled to the other one of the body and the door, a detent member slidably fitted into and retained by the case so as to retain the door at a predetermined open position in cooperation with a detent face of the check plate, and a resilient member that is provided in a compressed state in a housing chamber defined between an outer end face of the detent member on a side opposite to the check plate and an inner end face of the case opposite the outer end face, said resilient member operable to generate a detent force between the detent member and the detent face, wherein the resilient member substantially and tightly fills the housing chamber; and wherein the resilient member comprises a hard portion having a relatively high modulus of elasticity, and a soft portion having a relatively low modulus of elasticity.
