(Embodiment 1)
As shown in FIG. 1 to FIG. 5, the suction port 1 is formed on the lower surface, the fan motor 2 is provided inside, and one end side is placed on the peripheral portion of the suction port 1 of the main body 3 installed on the wall surface 22 such as a kitchen. A plurality of supported guard wires 4 are arranged in a substantially inverted conical shape, have an oil droplet circulation hole 5 on the other end side, and are provided with a screw hole 7 into which a mounting screw 6 is screwed at the center. A hub 9 provided with an anti-rotation hole 8 is provided at an outer position of the hole 7, a guard portion 10 is formed, and a substantially reverse L-shape is formed on the side wall 11 in a reverse hook shape attached to the hub 9 which is the lower surface of the guard portion 10. Slot 12 having a groove is provided at equal intervals in the circumferential direction, and is provided with a detent pin 14 that engages with the through hole 13 of the mounting screw 6 and the detent hole 8 provided in the hub 9. And the rotation prevention means 16 is formed by the rotation prevention hole 8 provided in the hub 9 and the rotation prevention pin 14. It has a bowl shape and is formed larger than the diameter of the hub 9, and has a cylindrical portion 17 inserted into the outer periphery of the support portion 15. The cylindrical portion 17 swings in a slot 12 formed in the support portion 15. Protrusions 18 that can be freely engaged are provided in the same number and at the same intervals as the slots 12 to form the oil receivers 19, and recessed portions in which the protrusions 18 are received and locked at the back of the slots 12 formed in the support portion 15. A holding portion 20 is formed, and a tapered surface 21 is formed at the entrance of the slot 12.

  In the above configuration, when the oil receiver 19 is attached, the oil receiver 19 is formed in the slot 12 of the support portion 15 that is non-rotatably attached to the hub 9 provided in the guard portion 10 via the anti-rotation means 16 by the attachment screw 6. When the cylindrical portion 17 is inserted into the outer periphery of the support portion 15 so that the projected protrusion 18 is engaged, and the oil receiver 19 is rotated to the right by approximately half a turn or less along the slot 18, the protrusion 18 Moves to the back of the slot 12, and when the oil receiver 19 stops rotating in this state and is released, the oil receiver 19 is lowered by its own weight, and the protrusion 18 engages with the concave holding portion 20. The oil receiver 19 is attached.
