PROBLEM TO BE SOLVED: To provide a sliding key which enables reduction of a manufacturing time, a price, and manufacturing processes, and though does not cause operation failure or inoperability even in a high-temperature and high-load use environment, and to provide a continuously variable transmission using the sliding key.SOLUTION: A sliding key 1 for rotation prevention and power transmission engages with a slide cylinder to be slidable in an axial direction of a rotation shaft, and engages with the slide cylinder to follow the rotation shaft to be rotatable around the rotation shaft. The sliding key has resin layers 3 having a sintered metal substrate 2 and a resin composition using an aromatic polyether ketone-based resin as a base. The resin layers 3 are laminated through injection molding, and integrally provided to have a thickness of 0.1-0.7 mm on a surface sliding with at least the slide cylinder of the sintered metal substrate 2. |
