PURPOSE:To eliminate the need to support an enclosure body during work and hence maintenance efficiency by clamping a flange section hinged with the bottom of a main body case of said enclosure body with the bottom of the main body case and its support section, rotating the enclosure body when the enclosure body is removed, and moving a notch section to a position where said notch section corresponds to the support section. CONSTITUTION:A plurality of support plates 7 are laid out in the outer periphery section of an opening section 10 at as proper span on a bottom 6 of a main body case 1. A plurality of notched sections 8, which allow the support plates 7 to pass by, are laid out on a motor base 5 at a position meeting with a plurality of support plates 7. When a plurality of screws 11, which mount the motor base 6 with a base plate 6, are removed, the motor base 5 is supported with the support plates 7 fixed with the base plate 6. When the motor base 5 is rotated, the position of the notched sections 8 corresponds to that of the support plates 7 of the bottom plate 6, which can be removed from the main body case 1 together with a motor 4 and a blade. They can be mounted on a procedure reverse to removing work. |
