Claims

[Scope of utility model registration request]

A switch that opens and closes a damper by screwing it into a cylindrical guide member that has a thread groove formed on its outer circumferential surface and is rotated by a reversible rotary motor and is moved up and down by the rotation of the motor, and also detects the fully open and fully closed positions of the damper. In a damper opening/closing mechanism for a rooftop ventilation fan in which the rotation of the motor is controlled by a mechanism, the switch mechanism includes two shafts installed in a switch box provided close to an opening/closing movement area of the damper. , a rotating body that is slidably inserted into one shaft and has a leaf spring wound around it, and a wire that is screwed into the other threaded shaft, winds the leaf spring, and has one end attached to the damper. It consists of a pulley around which the other end is wrapped, which rotates and moves in the axial direction as the damper moves up and down, and at least one switch that is cut and turned off as the pulley moves in the axial direction. Features a fully open/closed damper detection mechanism for rooftop ventilation fans.
