Title: VENTILATION SYSTEM COMPONENT AND VENTILATOR
Abstract:
A ventilation terminal (1) installed in a duct comprises: a flange member (4) provided with a cylindrical connecting tube portion (2), and a flange portion (3) projecting from one end portion of the connecting tube portion (2) in the radially expanding direction; and a grill member (5) that has a ventilating portion (5a) having a ventilating structure, and frame portions (5b) rising from the periphery of the ventilating portion (5a), the grill member (5) being detachably attached to the flange member (4) inserted into the frame portions (5b). The grill member (5) has at least a pair of protrusions projecting inward of the frame portions (5b) with a difference in protrusion direction being 180 degrees. The flange portion (3) is provided with: a pair of arched latching structures (9) projecting in the radially expanding direction of the connecting tube portion (2) with a difference in protrusion direction being 180 degrees; and curved slits (10) adjacent to the respective latching structures (9) on the center side of the connecting tube portion (2) and having the same curvature as the latching structures (9). The distance between the distal ends of the pair of latching structures (9) is equal to or greater than the distance between the frame portions (5b) of the grill member (5).
