Claims

[Claims for Utility Model Registration] Installed between a fixed frame fixed to an opening for a skylight and an opening/closing frame covered with a plate-like member and pivotally supported to be tiltable with respect to the fixed frame. An automatic opening/closing device for a skylight, comprising: a motor fixedly installed with respect to the fixed frame; a gear train rotationally driven by the motor; a final stage receiving gear of the gear train; and the opening/closing frame. In an automatic skylight opening/closing device comprising a link mechanism interposed between the gear train, the main gear of one specific reduction stage in the gear train is capable of meshing with and disengaging from the main gear of the specific reduction stage. An integral body consisting of a received gear that is slidable in the axial direction as shown in FIG. a rotor having a conical portion attached to be rotatable relative to a connecting member; a means for limiting a relative rotation angle of the rotor; and a means for restricting the relative rotation in a direction of restoration. A biasing spring means; a plurality of grooves provided in the conical surface of the rotor in the strand direction; and engaging with at least one of the plurality of grooves to rotate the rotor. A skylight comprising: a manually operated member that locks and slides in the axial direction by pressing a conical surface; and a compression spring that biases in a direction to restore the sliding movement. Automatic opening/closing device.
