A flange (3b) is formed at an intermediate portion of the transmission shaft (3), and a rear portion of the flange (3b) is passed through the inside of the bearing member (7). As a result, the transmission shaft (3) is supported by the fixed base (1) so that it can rotate but does not move in the axial direction. A worm portion (3c) that meshes with the teeth of the gear portion (2a) of the drive lever (2) is formed between the small diameter portion (3a) and the flange (3b) of the transmission shaft (3). An annular groove (8) is formed in the rear part of the transmission shaft (3) protruding from the rear surface of the fixed base (1), and the rear part thereof is a prismatic part (3d).

The handle device (4) includes a handle base (9) fixed to the rear portion of the transmission shaft (3) and a handle (10) rotatably attached to the handle base (9). .. A hole (11) is formed in the front surface of the handle base (9), and the rear portion of the transmission shaft (3) is fitted in the hole (11). A square cross section (11a) is formed at the rear end of the hole (11), and a prismatic section (3d) of the transmission shaft (3) is fitted in this section. Further, the tip of the set screw (12) screwed into the handle base (9) from the outside is fitted in the annular groove (8) of the transmission shaft (3). As a result, the handle base (9) is fixed so as not to rotate or move axially with respect to the transmission shaft (3). The handle base (9) is formed with a notch (13) that is open at the rear side and the radially outer side by cutting out the rearward and radially outwardly protruding portion in the plane including the axis of the transmission shaft (3). A recess (14) having a rectangular cross section is formed so as to extend forward from the front end of the notch (13). The base end of the handle (10) is fitted in the notch (13) of the handle base (9), and is rotatably supported by the pin (15) that is perpendicular to the axis of the transmission shaft (3). .. A cylindrical surface portion (10a) centered on the pin (15) is formed at the base end of the handle (10), and a leaf spring (16) that is pressed against the cylindrical surface portion (10a) is formed in the recess (14). It is provided. Two notches (engaging portions) (17) (18) are formed in the cylindrical surface portion (10a) of the handle (10) at predetermined intervals in the circumferential direction. The cross section of the spring (16) has a semicircular shape with the handle (10) side being convex, and both ends thereof are pressed against the corners of the recess (14). A protrusion (engagement portion) (19) that selectively engages with one of the two notches (17) (18) of the handle (10) is formed in the center of the spring (16). ing. A knob (20) is rotatably attached to the rotating end of the handle (10).

At this time, in the axial direction of the transmission shaft (3), the turning end of the handle (10) extends rearward and radially outward from the base end, and the knob (20) is substantially parallel to the transmission shaft (3). ing. In this state, when the handle (10) is rotated around the transmission shaft (3), the transmission shaft (3) also rotates, and the worm part (3c) and the gear part (2a) of the drive lever (2) are rotated. ), The drive lever (2) is rotated, and the arm of the window stay (not shown) is rotated to open and close the shoji attached to the window stay. At this time, since the handle (10) is fixed in the operating position by the spring (16) and the handle (10) does not rattle, the handle operation is smooth.

When the handle (10) is rotated clockwise about the pin (15) from the state of FIG. 2, the protrusion (19) of the spring (16) causes the first notch (17) of the handle (10). Then, the spring (16) is elastically deformed by being pushed by the cylindrical surface portion (10a) of the handle (10). When the handle (10) is further rotated in the same direction, the handle (10) is folded and the protrusion (19) of the spring (16) is folded into the second notch () of the handle (10) as shown in FIG. Fit in 18) and hold the handle (10) in the folded position. At this time, with respect to the axial direction of the transmission shaft (3), the rotating end of the handle (10) extends forward and radially outward from the base end and does not significantly project rearward. Therefore, the handle (10) does not disturb the opening and closing of the curtain.

When the handle (10) is rotated counterclockwise around the pin (15) from the state of FIG. 4, the handle (10) is returned to the operation position of FIG. 2 again. Also at this time, the spring (16) is elastically deformed to allow the handle (10) to rotate.
