であつた。 It is desirable that the operation shaft for opening and closing the drain valve of a washing machine should be able to move in an articulated manner, but in order to achieve this in an articulated manner, structures such as those shown in FIGS. 1 and 2 have conventionally been adopted. In Figure 1, a tension spring 2 is connected to the free end side of a cam 1, one end of which is pivotally supported, so that the cam 1 moves articulately when it rotates left and right from its dead center. At this time, the drain valve is opened and closed by pulling the wire 3 connected to the cam. In FIG. 2, the operating shaft 4 has a square cross section and is sandwiched between two leaf springs 5 so that it can rotate articulately. However, these configurations were difficult to assemble and were not suitable for assembly line work.

ヤー１８を接続している。 In view of these points, this proposal aims to save power without using a separate spring, and as explained based on Figure 3 and below, 6 is a control base made of synthetic resin; A conical recess 7 is integrally formed on the side surface, a bearing cylindrical portion 8 is integrally formed at the tip of the recess, and notches 9 are provided at four locations at the tip of the cylindrical portion. 10 is a decorative board adhered to the surface of the control base. Reference numeral 11 denotes a pivot that is inserted into the bearing tube 8. The pivot is made of synthetic resin and has a hollow shape, and has a cam 12 integrally formed at its tip.
A convex portion 13 is formed on the side surface of this pivot 11, and circumferentially long through holes 14 are bored at both ends of the convex portion to reduce the elasticity of the convex portion in the direction of protrusion and retraction. increasing sex. This pivot 11 is inserted into the bearing cylinder part 8, and the convex part 13 is fitted into the notch 9 of the bearing cylinder part, and a pin 16 is inserted into a hole 15 bored in the shaft to prevent it from coming out. . An operating knob 17 is attached to one end of the pivot 11 installed in this way.
A wire 18 for opening and closing the valve is connected to the cam 12 at the other end.

メントは小さく、耐久性を増すことができる。 As described above, in the present invention, since the convex portion 13 of the pivot fits into the notch 9 of the bearing cylinder, the pivot can be articulately rotated by the operation knob 17, and power saving is generated. There is no need to use a separate spring for tightening, the number of parts is reduced, and assembly is easy. In addition, by simply inserting the pivot 11 into the bearing cylinder part 8, the convex part 13 on the shaft side will fit into the notch 9 in the bearing cylinder part.
Since they fit together, no great force is required to fit them together. Also, since through holes 14, 14 are bored at both ends of the protrusion 13 provided on the pivot side, this protrusion 〓〓〓〓
The elastic force in the protruding and retracting direction becomes large, and the pivot shaft 11 can be rotated with a small force. Furthermore, since the bearing cylinder part 8 is formed at the tip of the conical recess 7 formed in the control base, the distance a from the connecting part of the bearing cylinder part and the conical recess to the tip of the bearing cylinder part is small. As a result, even if the wire 18 is connected to the tip of the pivot, the moment applied from the wire to the bearing cylinder portion 8 via the pivot is small, and durability can be increased.
