PURPOSE:To allow a casing and a cowling to be accurately and easily attached to and detached from a preset position in a comparatively broad space by making an apron composed of synthetic resin and obtaining the mounting structure whose attaching and detaching operation is possible from the outer circumferential surface. CONSTITUTION:The upper end peripheral section 38 of an apron 30 is fit in an engagement groove 39 provided at almost all the circumference on the bottom outside surface of a bottom cowling 17 and is provided with a primary sealing function for sea water and the like. On the other hand, the lower end peripheral section 40 is made to contact a shoulder section 41 provided at the outside rear of a casing 13. Then, it is fixed with a tapping screw whose attaching and detaching operation is possible from the lateral direction on the outside surface of the apron 30. As a result, attaching and detaching operation can be done in a comparatively broad space and the apron 30 can accurately and easily be attached to and detached from the preset position of the causing 13 and the bottom cowling. In addition, by making the apron 30 composed of synthetic resin, the salted corrosion of a female screw section with which the tapping screw 34 is engaged can be prevented and attaching and detaching are enabled for a long period of time. |
