Abstract
To facilitate subassembly of a power transmitting (viscous coupling) apparatus without use of a hub, the apparatus comprises a multistep shaft formed with an input portion and a multistep shoulder portion steppedly narrowed in diameter from the input portion to the opposite side; a casing fitted to the multistep shaft from the opposite side of the shaft and formed with an output portion; and two sets of resistance plates engaged with and arranged along the axial direction of each of the multistep shaft and the casing, within a working chamber formed between the shaft and the casing, so as to intervene between two other resistance plates.
