<p>PURPOSE: A device is provided to increase a strength in an axial direction and in turn also the natural frequency of a turbosupercharger, to improve accessibility to a constitution part situated at the internal part of the turbosupercharger, and to reduce its maintenance cost. CONSTITUTION: This device is constituted such that at least one of coupling elements(22,23) formed as a part of which a main leg consists and at least one of coupling elements(24,25) formed as the constitution part of a bearing casing(17) are arranged in a manner that the main leg(1) and the bearing casing(17) are intercoupled in a state to effect shape coupling in a vertical direction. Further, at least one additional coupling element(40) situated capably of dissociation is situated in a manner that the main leg(1) and the bearing casing(17) are axially intercoupled in an engaging state.</p> |
