Abstract:
1. A flywheel comprising: a flywheel cover including at least one recessed portion; a sensor plate attached to the flywheel cover, the sensor plate including at least one first portion, with the first portion of the sensor plate axially confronting the at least one recessed portion; and a plurality of coupling portions fixedly coupling adjacent portions of the flywheel cover to adjacent portions of the sensor plate, respectively, with the adjacent portions of the flywheel cover being disposed circumferentially adjacent to the at least one recessed portion in both circumferential directions of a center axis of the flywheel relative to the at least one recessed portion, respectively, with the adjacent portions of the sensor plate being disposed circumferentially adjacent to the first portion in both circumferential directions of the center axis of the flywheel relative to the first portion, respectively, with the coupling portions being formed at circumferentially spaced apart locations with a circumferential spacing therebetween, the at least one recessed portion and the first portion being circumferentially disposed within the circumferential spacing between the coupling portions, the first portion having less rigidity than the adjacent portions of the sensor plate such that the first portion deforms as the adjacent portions of the sensor plate are deformed in response to deformation of the flywheel cover.
