Abstract: A shelf for bus wherein shelf brackets are fitted into first and second rails to enable the shelf brackets to be uniformly intervened therebetween, thereby allowing shelf plates to be identical in length thereof thus, reducing production cost. A lens is rotably and slidably opened and closed relative to a shelf plate, enabling easy replacement of the lens and lamp. The shelf includes a first rail extensively secured lengthwise to a roof frame of the bus, a second rail securely installed at a side panel of a bus interior in the same length as that of the first rail, a shelf bracket formed at both ends thereof with a first and a second fitting part and secured at the first and second rails for sliding while fitted into the first and the second rails, and a shelf plate fixed at an upper surface of the shelf bracket.
