Abstract

A door checker for an automobile includes: a case fixed to one of a body and a door of the automobile; a check lever movably penetrating the case, oscillatably axis-supported by the other of the body and the door, and provided with a rack on one side face; a pinion meshed with the rack and rotatably housed in the case; a movable shoe housed in the case so that the movable shoe can be engaged with and disengaged from a tooth portion of the pinion; and a check spring for biasing the movable shoe in the direction of engagement with the pinion. The door is held at an arbitrary opening degree by an engaging force of the movable shoe with the pinion due to a biasing force of the check spring. Thus, it is possible to easily set a large number of steps in an opening degree for holding the door.

Claims

1. A door checker for an automobile, comprising:

a case fixed to one of a body and a door of the automobile;

a check lever movably penetrating the case, oscillatably axis-supported by the other of the body and the door, and provided with a rack on one side face;

a pinion meshed with the rack and rotatably housed in the case;

a movable shoe housed in the case so that the movable shoe can be engaged with and disengaged from a tooth portion of the pinion; and

a check spring for biasing the movable shoe in the direction of engagement with the pinion,

wherein the door is held at an arbitrary opening degree by an engaging force of the movable shoe with the pinion due to a biasing force of the check spring.

2. The door checker for an automobile according to claim 1, wherein shoe pushing-up means is provided in the case so as to separate the movable shoe from the pinion with relative movement of the case and the check lever.

3. The door checker for an automobile according to claim 1, wherein a rotational axis of the pinion is arranged in parallel with an axis for oscillatably connecting the check lever to the other of the body and the door.

4. The door checker for an automobile according to claim 2, wherein a rotational axis of the pinion is arranged in parallel with an axis for oscillatably connecting the check lever to the other of the body and the door.
