The pin 71 is provided in the housing 40 with the vertical direction as the axial direction. The driven gear 72 is rotatably provided with respect to the pin 71. A driven gear 72 meshes with a drive gear 524 of the output mechanism 521. One end of the arm body 73 is connected to the driven gear 72. The other end of the arm body 73 is connected to the lower part of the shoji 2. With the shoji 2 closed, as the driven gear 72 rotates in one direction around the axis of the pin 71, the other end of the arm body 73 pushes the lower part of the shoji 2 toward the outdoors, and the shoji 2 opens. . With the shoji 2 open, as the driven gear 72 rotates in the other direction around the axis of the pin 71, the other end of the arm body 73 pulls the lower part of the shoji 2 indoors, and the shoji 2 closes. .

A method for the operator to manually open and close the shoji 2 will be explained. The fitting between the fitting protrusion 44 of the casing 40 and the fitting hole 61h of the cover 60 is released, and the cover 60 is removed from the casing 40. The upper surface 513u of the second shaft 513A of the second reduction gear 513 is exposed in the operation hole 43 of the housing 40. The second shaft 513A can be rotated in one direction around the axis using a tool such as a flathead screwdriver through the operation recess 513d of the second shaft 513A. The large diameter gear 513B rotates together with the second shaft 513A. The large diameter gear 514B of the third reduction gear 514, which is meshed with the large diameter gear 513B, rotates. The transmission gear 523 that meshes with the small diameter gear 514C of the third reduction gear 514 rotates. The driven gear 72 that meshes with the drive gear 524 rotates. As the driven gear 72 rotates in one direction around the axis of the pin 71, the other end of the arm body 73 pushes out the lower part of the shoji 2 to the outside, and the shoji 2 opens.

When the second shaft 513A is rotated in the other direction around the axis (opposite direction to the above), the second reduction gear 513, the third reduction gear 514, the output mechanism 521, and the driven gear 72 are rotated in the opposite direction to the above. move. The other end of the arm body 73 pulls the lower part of the shoji 2 indoors, and the shoji 2 is closed.

In the side-sliding window 100 configured in this manner, the driving force of the electric motor 501 is transmitted to the output mechanism 521 by the reducer 511 including the second reduction gear 513. The output mechanism 521 transmits the driving force to the shoji 2. As a result, the shoji 2 is electrically opened and closed. Since the second reduction gear 513 is manually operable, the shoji 2 can be easily opened and closed manually.

In the side sliding window 100 described above, the second shaft 513A of the second reduction gear 513 is manually rotatable. Thereby, by rotating the second shaft 513A, the large diameter gear 513B provided on the second shaft 513A can be rotated, and manual rotational force can be transmitted to the shoji 2.

In the side sliding window 100 described above, the operation hole 43 is formed in the housing 40 . An upper surface 513u of the second shaft 513A of the second reduction gear 513 is exposed in the operation hole 43.
Thereby, when the cover 60 is removed from the housing 40, the second shaft 513A can be manually rotated, and the rotation operation can be performed smoothly.

In the side sliding window 100 described above, the cover 60 covers the operation hole 43 and the screw hole 45 of the housing 40. Thereby, it is possible to suppress water from entering the inside of the casing 40 through the operation hole 43 and the screw hole 45, and it is possible to improve waterproofness.

In the side-sliding window 100 described above, the cover 60 mainly covers the top, both sides, and the front of the housing 40. When it is desired to change the color tone, design, and material of the cover 60, it is sufficient to replace only the cover 60 without replacing the housing 40 and the unit body 50. The boundary between the upper housing part 41 and the lower housing part 46 is covered with the cover 60 and is not exposed.

The various shapes and combinations of the constituent members shown in the embodiments described above are merely examples, and can be variously changed based on design requirements and the like without departing from the spirit of the present disclosure.
