PURPOSE:To remove an apron easily by engagingly locking a rear side apron vertically to a bottom cowl through an engagingly locking means and moving the rear side apron in a specified direction against the bottom cowl through the engagingly locking means, thereby releasing the engagingly locked state. CONSTITUTION:Fitting bolts 44 are removed to take a front side apron 40 out of a propulsion unit so as to expose a fitting bolt 46. This fitting bolt 46 is removed, and a rear side apron 42 is pulled horizontally backward. Accordingly, elastic dampers 60 so far engagingly locked at the small diameter parts 52A of fitting holes 52 are moved to the large diameter parts of the fitting holes 52. As the head parts of the elastic dampers 60 are smaller in diameter than the large diameter parts 52B, the whole engagingly locking means slips out downward, and thus the apron 42 can be removed. As a result, a cutout 64 is exposed at the rear part of a bottom cowl 22, and the engagingly locked state against the hook of a disengaging mechanism is released through the cutout 64 so as to remove a top cowl. |
