Abstract
A door checker which can be advantageously utilized for driving automotive equipment such as a seat belt reacher system in synchronization with the opening and closing action of the vehicle door. By appropriate arrangement of a spring and a taper in the door checker member, the force required to open and close the door is not unduly increased. By proper arrangement of the spring, the side thrust from the door checker member is always directed in one direction, whereby the structure for supporting the side thrust is simplified.
