Abstract
In a door checker for an automobile, including an intermediate recess which is formed in a side face of a check lever and deeper than a ball guide groove and into which a check ball is fitted by a biasing force of a check spring in order to generate a moderation resistance at a position of at least one medium opening degree of a door, the intermediate recess is formed so that a second opening width in a direction intersecting a centerline of the ball guide groove is larger than a first opening width along the centerline of the ball guide groove. Thus, the feeling of moderation upon fitting between the check ball and the recess is improved, and the generation of an abnormal sound during passing of the check ball through the recess by rapidly opening or closing the door is prevented.
