Claims

[Scope of utility model registration request]

A U-shaped type having a side wall portion fixed to the vehicle body side and upper and lower flange portions extending in the same direction at approximately right angles from the upper and lower ends of the side wall portion, with a shaft hole for connection formed in the upper and lower flange portions. A molded check bracket,
A check arm that is engaged at one end with a holding mechanism on the door side and has a shaft hole for connection formed at the other end, and is inserted and fitted into the shaft hole for connection formed in the check bracket and the check arm. and a connecting member that swingably connects the check arm to the check bracket, the door check holding the door at a predetermined position when the door is opened by the check arm connected to the check bracket and the holding mechanism. In the above connection member structure, an elastically deformable cylindrical cotter pin is fitted into the connection shaft hole formed in each of the check bracket and the check arm and swingably supports the check arm on the check bracket; A member inserted into the cotter pin from one end of the cotter pin, which has a head shape that can be engaged with a fastener, a shaft portion with a male screw, and a shaft portion located directly below the head. A bolt consisting of a truncated cone-shaped tapered part formed integrally with or separately from the head and shaft part, and the tapered part is fitted into one end of the cotter pin when inserted into the cotter pin. and a female threaded portion that is inserted from one end of the split pin and is threaded onto the shaft portion of the bolt that protrudes from the other end, and a female threaded portion that is formed integrally with or separately from the female threaded portion and that is connected to the bolt. and a nut having a truncated cone-shaped tapered part that is fitted into the other end of the cotter pin when screwed together, and is fitted to both ends of the cotter pin by adjusting the tightening of the bolt and nut, respectively. By adjusting the degree of fitting of the tapered part into the end of the cotter pin and adjusting the degree of expansion of the outer circumference of the cotter pin fitted into the shaft hole, the degree of fit between the shaft hole and the cotter pin can be adjusted. Door check connecting member structure that allows for adjustment.
