PROBLEM TO BE SOLVED: To provide a pulley which achieves improvement of the workability in maintenance of a sheave, and to provide a deck crane including the pulley.SOLUTION: A pulley includes: a sheave 20 which is provided so as to rotate around a support shaft 32; and a protection cover 40 which is provided so as to cover an outer peripheral surface of the sheave 20. The protection cover 40 is movably disposed so as to be switched between a closed position, at which the protection cover 40 covers the outer peripheral surface of the sheave 20, and an open position, at which the protection cover 40 partially exposes the outer peripheral surface of the sheave 20.SELECTED DRAWING: Figure 3
