A support shaft is received in a socket for relative rotation. A first hollow space penetrates through the support shaft. A first hollow member extends in a first direction from the tip end of the support shaft. The first hollow member defines a second hollow space extending in the first direction. The second hollow space receives a rotation shaft. A second hollow member extends in a second direction opposite to the first direction from the tip end of the support shaft. The second hollow member defines a third hollow space extending in the second direction from the tip end of the first hollow space. The electronic apparatus allows penetration of the wire through the first and third hollow spaces. No additional space is required around the second hollow member for locating the wire. The electronic apparatus is thus allowed to enjoy a reduced size or volume.
