Document Type and Number:
Japanese Patent JP2018135633
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a window opening/closing device which includes a sash opening angle switching mechanism which can compactify depth and width of a base body and which does not cause increase in manufacturing cost.SOLUTION: A window opening/closing device 1 for opening/closing a sash includes: a worm 4 which extends substantially in an indoor outside direction by being supported by a base body 2 fixed to a window frame and which is coaxial with a driving shaft 3; a worm wheel 5 which meshes with the worm 4, and which oscillates around a vertical shaft core B1; an oscillation arm 6 which oscillates integrally with the worm wheel 5 and which extends in an outdoor direction horizontal plane; and a connection arm for connecting the oscillation arm 6 and the sash. The worm wheel 5 and the oscillation arm 6 are separate components. The oscillation arm 6 has a notch part 6E at a base end part 6A, and by protruding/retracting a locking piece 10 supported by the base body 2 and oscillating around the vertical shaft core B2 in the notch part 6E, a sash opening angle is switched between a fully-opened angle and a half-opened angle.SELECTED DRAWING: Figure 10
