Test equipment is used.

This opening/closing body testing device generally includes a return means such as a spring that biases the opening/closing body in the closing direction, and a tensioning means that intermittently pulls a member such as a belt connected at one end to the opening/closing body using a cylinder or the like. However, in addition to the above-mentioned means, a test device for an opening/closing body provided with a locking mechanism is provided with a lock release means for releasing the locking mechanism. Then, with the lock mechanism released by the lock release means, the opening/closing body is opened by the pulling means, and then, by releasing the tensile force by the pulling means, the opening/closing body is moved to close by the return means. In this way, the opening/closing body is repeatedly opened and closed.

However, in the conventional opening/closing body testing device, as shown in FIG. It was worn,
The structure was such that the belt A and the opening/closing body B were mechanically connected. Therefore, for example, the lock release means does not operate normally, or the wire E
If an abnormality occurs such as the lock mechanism not being released even though the release member (outer handle) G of the lock mechanism provided on the opening/closing body B is operated in the release direction via the engagement member F, the lock A situation occurs in which the opening/closing body B is forcibly pulled in the opening direction by the above-mentioned tensioning means without being released, and the opening/closing body B and its locking mechanism are damaged, making it impossible to continue the test. .

Further, according to the above configuration, it is necessary to drill holes in the opening/closing body B for inserting the bolts C and C, and to tighten the bolts C and C.
In addition, since the mounting position of the bracket D to the opening/closing body B cannot be adjusted, the opening/closing body B has no installation position on the vehicle body.
