Abstract

A door checker for an automobile includes a case secured to a door, and a check plate mounted to extend through the case and supported on a body. A pair of detent members and resilient means for urging the detent members against opposite sides of the check plate are accommodated in the case. The check plate is provided with notches in which the detent members are brought into engagement to retain the door at a predetermined medium opening degree, and with a full-opening stopper means adapted to receive an outer side of the case to define an opening limit for the door. In the door checker, a section of each of the opposite sides of said check plate, where each of the detent members is moved from the medium opening degree to the opening limit for the door, is formed as a continuous surface having no unevenness. Thus, a door-opening load can be prevented from changed quickly during movement of the door from a predetermined medium opening degree to the opening limit, thereby preventing the quick opening of the door to the opening limit against a user'"'"'s wish.

Claims

1. A door checker for an automobile, comprising a case secured to one of a body and a door of the automobile, and a check plate mounted movably to extend through said case and supported on the other of said body and said door, a pair of detent members and resilient means being accommodated in said case, said detent members being mounted to come into contact with opposite sides of said check plate, said resilient means being adapted to exhibit repulsive forces to urge said detent members against the opposite sides of said check plate, said check plate being provided with notches in which said detent members are brought into engagement to retain the door at a predetermined medium opening degree, and with a full-opening stopper means adapted to receive an outer side of said case to define an opening limit for the door,

wherein a section of each of the opposite sides of said check plate, where each of said detent members is moved from the medium opening degree to the opening limit for the door, is formed as a continuous surface having no unevenness.

2. A door checker for an automobile according to claim 1, wherein said continuous surfaces are formed as slants rising toward the opening limit for the door.

3. A door checker for an automobile according to claim 2, wherein said slants are formed to generate frictional forces between said slants and said detent members for retaining the door at the opening limit.
