PROBLEM TO BE SOLVED: To provide a structure of a window opened and closed in a sliding movement or a push-opening movement by which a tilt of an inner window provided in a C-shaped inner frame is prevented and smooth opening and closing operation is obtained. SOLUTION: A whole window 1 comprises a plurality of inner windows 10, the C-shaped inner frames 20 onto which the inner windows 10 are journaled, respectively, and an outer frame 30 having a plurality of tracks on which all of the inner frames 20 are placed further. An angle adjusting structure is provided at a joint part of a vertical frame 23 and a lateral frame of the C-shaped inner frame 20. With the angle adjusting structure, the vertical frame 23 and a lower lateral frame 22 of the C-shaped inner frame 20 are adjusted to tilt to each other to have a skew angle slightly larger than 90 degrees so that the vertical frame 23 may have an outward skew angle to the lower lateral frame 22. When used, the outward tilt of the vertical frame 23 and a torque generated by a weight of the inner window 10 are made to be balanced so that the vertical frame 23 and the lower lateral frame 22 of the C-shaped inner frame 20 may be in a state of joint at 90 degrees.
