A computer device using a shielding door comprises a door; at least one post fixed to the door; at least one pivotal portion installed to the shielded surface and including at least one groove for receiving the post and thus the post can rotate in the groove. The groove includes a first receiving chamber and a second receiving chamber. The first receiving chamber receiving the post which has two shaft portions; and the second receiving chamber provides a space so that the other portion of the post can move therein. The first receiving chamber has two lateral walls. Each lateral wall has a respective hole so that the two shaft portions run across the two holes and positioned therein. An elastomer has a free end for confining the shaft portions. Thereby, the shaft portions will not leave from the holes and thus rotate therein steadily.
