Description

[Detailed Description of the Invention] The present invention relates to a compressor constituting a vehicle cooling compressor, and an object of the present invention is to make the installation of the compressor strong and easy.

Another object of the present invention is to allow the use of various mounting brackets and to allow the mounting angles such as the positions of the suction port and discharge port to be selected as appropriate.

Conventional vehicle cooling compressors have been installed on the engine by forming two protruding mounting ears on the front and rear of the cylindrical casing, and bolting these mounting ears to a bracket fixed to the engine. .

However, since this conventional example uses mounting ears that are formed protrudingly at a predetermined position on the compressor, a specific bracket must be created depending on the type of engine to which it is installed, making it very convenient.
