Abstract:
1. An automobile door checker connected between a body and a door of an automobile, the door checker comprising: a case secured to one of the body and the door; a check plate that runs movably through the case and the check plate is linked to the other of the body and the door; a shoe holder that is held by the case and the shoe holder is able to move towards and away from the check plate; a shoe that is disposed in the shoe holder, the shoe comprising a first segment having a high frictional surface and a second segment having a low frictional surface for sliding on the check plate accompanying relative movement between the case and the check plate; and a check spring that resiliently urges the shoe holder toward the check plate within the case in order to press the shoe against the check plate; wherein the shoe is axially supported in the shoe holder so that the shoe can swing from a neutral position to forward and backward swing limits along the lengthwise direction of the check plate; wherein a return-to-neutral means for exhibiting a return force that makes the shoe return to the neutral position is connected to the shoe; wherein the contact area between the shoe and the check plate is arranged so that the frictional force in the contact area becomes smallest when the shoe reaches the shoe swing limits; and wherein the first segment includes a surface formed by embedding material having a high frictional coefficient.
