Abstract:

To provide a power transmission device capable of improving connection strength between a hub and a shaft by slightly raising a component cost.

In the power transmission device 10 for transmitting rotational force transmitted from an engine of an automobile to the shaft 21 of a variable displacement type compressor through the hub 14, a fastening means 30 for connecting the hub 14 and the shaft 21 is provided with a nut 34 screwed on a threaded shaft 32 of the shaft 21, and a washer 33 intervening between the nut 34 and the hub 14, and surface hardening treatment is applied to the washer 33. The fastening force of the nut 34 is imparted to the hub 14 through the washer 33, and thereby the hub 14 is prevented from being depressed, and surface hardening treatment is applied to the washer 33 to which the fastening force of the nut 34 is directly imparted, and thereby the washer 33 itself is not depressed or deformed.
