<p>PURPOSE: To reduce mechanical process and fastening stress thus attaining a secure fastening by abutting one of free ends of a bush having an inner and an outer screws, which are screwed with a fastening screw passing through fastening lugs of a first part and a female thread of a second part, on inner bearing faces of the fastening lugs via the fastening screw. CONSTITUTION: A fastening screw 8 passes through though holes 5a2, 5b2 of two pairs of fastening lugs 5a, 5b of a compressor (a first part) 5 of a cooler, flanges 11b, 12b of a common support (a second part) 2 provided to a crankcase 6 are female-threaded, a outer thread 13a of a bush 13 is screwed with female threads of the flanges 11b, 12b, and therefore one free end of the bush 13 abuts against bearing faces 5a1, 5b1 of the fastening lugs 5a, 5b. Consequently, a fastening stress of the fastening lugs 5a, 5b is made smaller, thus attaining a secure fastening by reducing mechanical process.</p> |
