PROBLEM TO BE SOLVED: To provide a sliding key stably operatable under even a using environment of a high temperature and high load, inexpensively manufacturable and capable of effectively making the most of resources and a pulley unit using the sliding key. SOLUTION: This sliding key 1 is provided so as to be stably operatable under even the high temperature and high load, to be inexpensively manufacturable and to effectively make the most of resources by making the key 1 as a composite by integrally joining a metallic compact 2 and a resin compact 3 formed separately and forming at least sliding parts on both side surfaces by the resin compacts 3. |
