<P>PROBLEM TO BE SOLVED: To provide a decorative panel which prevents a supporting pin from being mounted in a wrong direction, and a ventilation fan including the same. <P>SOLUTION: In the decorative panel 3 which has holding structures 12 for positioning a torsion spring 8 with a torsion ring part 9 sandwiched from the axial both sides, in two opposed locations at the back surface, on which a supporting pin 13 with a large diameter part formed at one end of an insertion part is inserted laterally from an insertion hole 19a into between holding pieces 15 and 17 and is fixed to the holding structures 12, and thus the torsion spring 8 is held by the holding structures 12 so that a locking leg 10 protrudes to the back surface, the holding structures 12 being inserted to an intake opening of the body in this state, and which is hung and supported by the body with the torsion spring 8, the holding piece 17 includes a rib 22 formed on a surface on an opposite side to the holding piece 15 to prevent the insertion part from interfering with the intake opening on contact with the large diameter part when the supporting pin 13 is inserted laterally from the insertion hole 19b into between the holding pieces 15 and 17. <P>COPYRIGHT: (C)2013,JPO&INPIT |
