PROBLEM TO BE SOLVED: To provide a range hood fan to simply and reliably lock an equalizing plate at a member on the hood side and release the locking. SOLUTION: A lock groove a1'-4 of a claw part a1-4 situated movably on one of a hood cover 6 or the equalizing plate 1 is locked in a lock hole a1'-1 of a lock piece a1-1 protruding in a relative direction from one of the equalizing plate 1 or the hood cover 6. This constitution prevents pull off the claw body a1-4 from the lock hole a1'-1 through lock relation between the lock groove a1-7 and the lock hole a1'-1 through a lock relation between the lock groove a1-7 and the lock hole a1'-1 without moving backward the claw body a1-4 even when an operation knob a2 is pushed by mistake against the energization force of a rebound spring a1-3. |
