Problems solved by technology

[0003] However, the operator's handle installed on the window opening and closing device can only be rotated by the amount of backlash between the worm and the worm wheel due to the position after operation, and the knob side hangs downward.
Such movement hinders the operability of the handle, and also leaves an impression of looking cheap. Therefore, there is a problem of degrading taste as a door and window equipped with such a window opening and closing device.

Abstract

The invention discloses a window opening and closing device, and a door and a window. The window opening and closing device (10) has a device main body (11) fixed on a window frame of door and window and a handle (12) arranged on the device main body (11) to freely rotate. The device main body is provided with a freely rotary worm (17) installed with the handle (12), a worm wheel (19) engaged and rotating with the worm (17), a connecting bar (30) delivering the movement of the worm wheel (19) to a movable portion of door and window and a worm guider (41) engaged with a shaft portion (36) of the worm (17) to prevent the handle (12) from moving. The worm guider (41)can prevent the worm from moving so as to prevent the handle from moving when the handle (12) drops.
