性を容易に高めることができる。Therefore, when a large impact is applied from the outside of the vehicle body 10, the door body 3 is deformed and at the same time moves relatively inward on the side sill 2 as illustrated in FIG. Then, the inclined surface 14 of the door main body stepped portion 15 becomes the inclined surface 16 of the side sill stepped portion 17.
Since the lower part of the door body 3 is locked to the side sill 2 which is a part of the vehicle body 10, the displacement to the inside of the vehicle compartment 4 is strongly suppressed, and the stepped portions 15 and 17 are Since the inclined surfaces 14 and 16 reliably engage with each other, the reliability of the restraining action against the inward displacement of the door body 3 can be easily enhanced.

いる。Further, when the central portion of the door body 3 is deformed to a relatively large extent inside the vehicle compartment 4 as in the case where a lateral impact is applied to the central portion of the door body 3, the door body is accompanied by this. The lower part of 3 inclines toward the inside of the passenger compartment 4, and therefore the inclined surface 14 of the stepped portion 15 of the door body also inclines toward the inside of the passenger compartment 4,
Although it is pulled to the central portion of the door body 3, since the inclined surface 14 is originally inclined inward and downward, the inclined surface 14 is firmly engaged with the inclined surface 16 of the side sill stepped portion 17 without slipping. As a result, the locked state of both inclined surfaces is hard to come off.

に抑制できるものである。That is, a stepped portion having a front inwardly inclined surface is formed on the front end surface of the front and / or rear door body, and the stepped portion is provided on the inner side in the vehicle width direction and on the rear outer side. A stepped portion with an inclined surface is formed on the rear surface of the front pillar and / or the center pillar, respectively, and a stepped portion with an inclined surface toward the rear inward is formed on the front and / or rear of the door body. By forming it on the end face, and inside the vehicle width direction of the stepped part, a stepped part with an inclined surface to the front outside is formed on the front surface of the center pillar and / or the quarter panel, respectively. When the door body is about to be displaced into the vehicle compartment due to a collision from, the inclined surfaces of the facing step portions are engaged with each other, and the front and rear peripheral portions of the door body are locked to the vehicle body, Similar to the above example, the door Body is one that can be reliably prevented from being displaced toward the cabin internal.
