The window unit of the invention comprises four peripheral channel members linked with corner members to form a window frame. Two glass panels are spaced by this frame to form an inner chamber, the louver blind structure of the invention being located completely therein. The louver blind structure comprises a plurality of horizontal slats pivotally supported at both their extremities and each having an integral toothed wheel engaging a complementary rack on an actuator bar, the latter positioned adjacent to a side peripheral channel member and being free to move upwards or downwards along it. This upward or downward movement imparts a pivoting movement to the slats. The louver blind structure further comprises a support channel member supporting a reversible electrical motor having a driving shaft. This shaft has an eccentric stud which engages the actuator bar and must therefore be kept properly alined so as to resist radial forces exerted thereon. When the driving shaft rotates, it imparts a linear upward or downward movement to the actuator bar, thus pivoting the slats consequently. The alignment of the shaft is done by means of an L-shaped plate bored and threadingly engaged by an alignment sleeve, the latter being coaxially engaged by the driving shaft and disposed adjacent the actuator bar. This alignment of the shaft reduces the chances of breaking the actuating parts of the louver blind structure.
