PURPOSE:To improve the workability of a fixing work or a cleaning work by a method wherein some slits are arranged at lower portions of a main body of hood and a front hood and some fixing fitting of which attaching and removing may easily be performed are arranged at the slits. CONSTITUTION:A front hood 6 is installed to a main body 1 of a hood in such a way as at first an upper engaging claw 8a is engaged with an engagement piece 8b, a fitting 7b is manually moved in a direction toward a reduced diameter of a spring 7d to form a clearance between the fittings 7a and 7b. The fixing fitting 7 is inserted into slits 2a and 2b which are aligned at the lower portions while the main body 1 of the hood and the front hood 6 are inserted into this clearance. When a hand is released from the fittings while they are located at the deepest position, the fittings 7a and 7b may fasten and fix the main body 1 of the hood and the front hood 6 with a tension force of a spring 7d and then their insertion fittings can be completed. Then, removal of the front hood 6 from the main body 1 of the hood can easily be carried out under an opposite sequence of the operation of the insertion fitting operation. Therefore the workability in fixing work or cleaning is remarkably improved. |
