Abstract:
1. A power transmission device of a clutchless compressor, the device comprising: a pulley rotated by a rotational force transmitted from a driving power source; a hub disposed in one side face of the pulley and connected to a driving shaft of a compressor; a drive-side connection member including a connection portion detachably connected to one side face of the pulley and a breaking portion connected to the connection portion and broken when a torque above a preset value is generated in the compressor; and a driven-side connection member including a plastic deformation portion formed on an outer peripheral face of the driven-side connection member, the driven-side connection member being connected to one side face of the hub and connected to the breaking portion, wherein after the breaking portion is broken into a driven-side remaining part connected on the driven-side connection member and a drive-side remaining part connected on the drive-side connection member, the plastic deformation portion is plastic deformed or is broken due to plastic deformation when a rotational shock is applied from the connection portion to the driven-side remaining part of the breaking portion.
