<p>According to the present invention, a housing coupling structure of a machine component is a structure fixating a housing receiving a machine component to a specific position, and a groove-shaped mount unit of which both end parts are opened is formed in the housing. The housing coupling structure comprises a coupling bush made of a synthetic resin material, coupled to be attached and detached from the mount unit. The coupling bush has a ring-shaped cross-section extended in a longitudinal direction of the mount unit to enable a screw thread to be formed on an inner circumferential surface by self-tapping. A rotation preventing unit composed of a non-circular cross-section is provided on one side of the mount unit to prevent the coupling bush from rotating with respect to the mount unit while the coupling bush is coupled to the mount unit. The coupling bush has a head unit to prevent rotation in correspondence to a shape of the rotation preventing unit.</p> |
