A side cover structure of an electric connecting box includes a connecting box main body, an upper cover, and a side cover covering a side opening at the connecting box main body. The side cover includes a vertical shaft through upper and lower supporters, and the connecting box main body includes a bearing. The shaft is engaged slidably and rotatably around the bearing. The bearing includes a stopper preventing the side cover from drawing out upwardly when the side cover in closed condition is moved upwardly, and a receiver supporting the side cover higher than that in closed condition when the side cover is moved upwardly and rotated toward a direction to open. The bearing includes curved upper and lower bearings, and the upper bearing has a top end portion, and a bottom end of the top end portion acts as the stopper to abut on the lower supporter. |

1. A side cover structure of an electric connecting box, comprising:
a connecting box main body, including a side opening for electric connection, a curved upper bearing and a curved lower bearing; an upper cover; and a side cover covering the side opening of the connecting box main body, and including a vertical shaft through upper and lower supporters, wherein the shaft is engaged with the bearing slidably in a direction of an axis thereof and rotatably around the axis, wherein the upper bearing includes a top end portion extending along a circular direction longer than the lower bearing, and a bottom end of the top end portion acts as a stopper abutting on an upper step of the lower supporter when the side cover is moved upwardly, so that it is prevented that the side cover is moved furthermore and drawn out upwardly, and wherein a top end of the upper bearing acts as a receiver supporting the upper supporter, a top end of the lower bearing acts as a receiver supporting the lower supporter, and a bottom edge of a vertical peripheral wall of the upper cover abuts on a top surface of the flange of the side cover when the side cover is rotated to be opened, so that the side cover is supported at a higher position when rotated to be opened than when closed, the upper cover cannot be mounted on the connecting box main body completely, and an incomplete closing of the side cover is detected. |
