PROBLEM TO BE SOLVED: To reduce manufacturing cost of a tilt window opening and closing device by reducing assembling manhours of a link mechanism. SOLUTION: Housings 25a and 25b are held between both first links 21a, and both first links 21a are arranged to both end sides of an output shaft 26. By the constitution, in a joint section between both first links 21a and second link 21b, when falling off between both links 21a and 21b is prevented, a falling off prevention means is not necessary to apply to both first links 21a. Accordingly, the construction of a tilt window opening and closing device becomes simple and, at the same time, since assembling manhours can be reduced, manufacturing cost of the tilt window opening and closing device can be reduced. |
