手。 An input shaft connected to a driving power source, a sealed rotary casing that surrounds the input shaft so as to be relatively rotatable and is filled with a viscous fluid, and a rotary casing provided coaxially with the input shaft on the output side of the casing. A plurality of drive disks are provided on the outer peripheral surface of the input shaft so as to be slidable in the axial direction at appropriate intervals, and the plurality of drive disks are provided on the inner peripheral surface of the casing. Donut-shaped driven disks are provided so as to be able to slide in the axial direction and are alternately overlapped with each other with a slight spacing between them, and the driving disks and the driven disks are moved by a pressing member that moves in the radial direction due to centrifugal force during rotation. In a fluid coupling equipped with a pressing means that allows the discs to slide in a direction that reduces the gap between each disc, a coil spring-like shape memory that hardens at a desired temperature and shortens the coil length is applied between each adjacent driven disc. A heat-treated shortened metal member having a shape memory effect and a spacer for securing a gap between the driven disks are arranged, and the shortened metal member is cured at the desired temperature and expanded by the same amount as the total shortened dimension of the shortened metal member. A fluid coupling characterized in that an elongated metal member having a shape memory effect and subjected to shape memory heat treatment in the shape of a coil spring presses the pressing member in a direction of increasing the pressing force of the pressing member.
