A sliding door is coupled to a casing having therein a receiving space, a port received in the receiving space, a first opening formed at the casing, and a first guide rail fixed to the casing to face the receiving space and positioned proximate to the first opening. The sliding door includes a frame body and a door body. The frame body is received in the receiving space and has a second guide rail, a resilient arm, and a second opening corresponding in position to the first opening. The door body is disposed between the casing and the frame body and slides along the first guide rail and the second guide rail to selectively block or unblock the first opening and the second opening. Accordingly, the sliding door structure is selectively opened or shut as needed, so as to protect the port.
