Abstract: A fastening member includes a bolt and a nut for attaching a compressor to a vehicle body. A non-circular relative rotation prevention portion is formed below a head portion of the bolt. A washer is non-rotatably press fitted around the relative rotation prevention portion. Before the attachment, the head portion and the washer are temporarily fixed with a space generated therebetween. An elastic body, which is attached to the compressor, is disposed between the washer and the nut. A cylindrical member is provided at an inner circumference of the elastic body. As a result, when the nut is screwed, an axial force of the nut is transmitted to the washer via the cylindrical member, and the space between the washer and the head portion is reduced, completing the attachment.

Abstract: The present invention provides a fastening member and a compressor apparatus capable of improving workability of assembling.

Abstract: An upper bush is secured to a bracket of a compressor unit, and a lower bush is abutted against a panel member of a vehicle body through a washer. A coil spring is interposed between the upper and lower bushes. A pipe member is inserted through the upper and lower bushes and the coil spring. A bolt is inserted through the pipe member and screwed into the panel member of the vehicle body. The compressor unit is resiliently supported floatingly by the coil spring. Vibration of the compressor unit is damped by friction generated by sliding contact between the pipe member and raised portions of the upper bush. When the vibration amplitude is large, respective projections of the upper and lower bushes abut against each other to suppress the vibration while absorbing impact.
