In a two-shaft pivotal mechanism for opening/closing and supporting a cover of the invention, a second pivot shaft connecting a pivoting member and the cover projects integrally from one of a pivoting member and a connecting piece on the cover, and an attachment hole for supporting the second pivot shaft is formed in another of the pivoting member and the connecting piece, so that the pivoting member and connecting piece are pivotally connected. The pivot limiting portion is provided between the connecting piece and the pivoting member, and limits pivotal operation therebetween to a predetermined angular range. A first pivot shaft connecting the pivoting member and a receptacle projects integrally from one of the pivoting member and the receptacle, and an attachment hole supporting the first pivot shaft is formed in another of the pivoting member and the receptacle, so that the pivoting member and the receptacle are pivotally connected.
