The rear regulating portion 43a abuts the first spring end portion 36a urged in the rear direction from the rear direction to the front direction, and regulates the movement of the first spring end portion 36a in the rear direction. The left regulating portion 43b has a protruding shape and projects forward, and a side surface is formed on the right side thereof, and the hooking portion is formed by this side surface shape. The left regulating portion 43b abuts on the first spring end portion 36a by this side surface to regulate the movement to the left. The right regulating portion 43c constitutes a side surface located on the right side of the rear regulating portion 43a, and abuts on the first spring end portion 36a to regulate the movement to the right. In the embodiment, an example in which the right regulating portion 43c is provided in the cutout portion 42c of the upper folded portion 42e is shown, but the present invention is not limited to this. For example, the right regulating portion 43c may be provided in the hole portion 42d of the lower folded portion 42f, that is, at a position adjacent to the front regulating portion 43d.

A hole 42d is formed in the lower folded portion 42f provided on the reinforcing member 42 located below the rear regulating portion 43a. The front end of the hole 42d constitutes the front regulating 43d. The front regulating portion 43d abuts on the first spring end portion 36a from the front and restricts the forward movement of the first spring end portion 36a indicated by the arrow E in FIG. The rear regulating portion 43a and the front regulating portion 43d described above position the first spring end portion 36a in the front-rear direction. At the time of assembly, the first spring end portion 36a is locked to the first regulating portion 43 through the hole portion 42d and the notch portion 42c.

The hole portion 42d and the notch portion 42c are formed large. The larger the hole 42d and the notch 42c, the greater the degree of freedom of the spring 36, and the easier it is to handle. Therefore, the spring 36 can be easily attached when the washing machine 1 is assembled.

Further, the front regulating portion 43d regulates the forward movement of the first spring end portion 36a indicated by the arrow E in FIG. As a result, the urging force of the spring 36 suppresses the urging force of pushing the spring 36 forward. Therefore, it is possible to prevent the inside of the hollow portion of the coil portion 36c of the spring 36 from coming into contact with the shaft 38. By suppressing the contact of the spring 36 with the shaft 38, friction is eliminated, so that the opening / closing torque at the time of opening / closing the lid 3 can be reduced, whereby the lid 3 can be smoothly opened / closed.

Further, the position where the first spring end portion 36a abuts on the rear regulating portion 43a is different from the position where it abuts on the front regulating portion 43d. That is, as shown in FIG. 10, the length L1 from the coil portion 36c of the spring 36 to the position where the first spring end portion 36a abuts on the rear regulating portion 43a is from the coil portion 36c of the spring 36 to the front regulating portion 43d. The length to the position where it comes into contact with the coil is larger than L2, that is, the rear regulating portion 43a is located farther from the coil portion 36c than the front regulating portion 43d. In this way, the first spring end portion 36a is between the rear regulating portion 43a that regulates the backward movement of the first spring end portion 36a and the coil portion 36c of the spring 36 that generates the urging force of the spring 36. By locating the front regulating portion 43d that regulates the forward movement of the spring 36, the movement of the spring 36 pushing the spring 36 forward by its urging force can be effectively suppressed by the principle of the lever. As a result, it is possible to prevent the inside of the hollow portion of the coil shaft of the spring 36 from coming into contact with the shaft 38, so that the generation of friction due to the contact is avoided, and the opening / closing torque at the time of opening / closing the lid 3 is increased. Since it is reduced, the lid 3 can be opened and closed smoothly.

The second spring end portion 36b is locked to the second regulating portion 44. The second regulating portion 44 to which the second spring end portion 36b is locked is a slit opened in the forward direction. At the time of assembling the washing machine 1, the second spring end portion 36b is attached and detached through the slit, and the spring 36 can be easily attached.

As shown in FIG. 11B, the second regulation portion 44 is a slit portion 44d provided on the bottom surface portion 42b, and the slit portion 44d has a rear regulation portion 44a, a left regulation portion 44b, and a right regulation portion 44c. It has. Note that FIG. 11B is a bottom view of the second regulation unit 44 viewed from the F direction shown in FIGS. 7 to 10.

The rear regulating portion 44a regulates the backward movement of the second spring end portion 36b, the left regulating portion 44b regulates the leftward movement, and the right regulating portion 44c regulates the rightward movement. When the spring 36 is attached, the second spring end portion 36b is urged backward and is in close contact with the rear regulating portion 44a, and is positioned by the rear regulating portion 44a, the left regulating portion 44b, and the right regulating portion 44c. ..

The slit portion 44d is opened in the forward direction, and when the lid 3 is closed with the second spring end portion 36b locked in a locking hole (not shown) provided in the top cover 5, the second spring portion 44d is opened. The spring end portion 36b rotates in the forward direction of the slit portion 44d.

The difference in the modified example is that the notched portion 42c in FIG. 8 is changed to the hole portion 46, which is a hole provided in the upper folded portion 42e, as shown in FIGS. 12 to 14. The first spring end portion 36a is locked to the hole portion 46 by being passed through the hole portion 46. When the first spring end portion 36a is attached, the first spring end portion 36a is urged to the rear wall of the hole portion 46 by the urging force in the rear direction of the spring 36. Other configurations are the same as those of the embodiments described in FIGS. 1 to 11.

With this configuration, the movement of the first spring end portion 36a in the front-rear and left-right directions is restricted in all directions, so that the first spring end portion 36a is prevented from falling out from the hole portion 46 when the lid 3 is opened and closed. As a result, the first spring end portion 36a is positioned in the front-rear and left-right directions, so that the spring 36 can be suppressed from moving in the front-rear and left-right directions when the shaft 38 is attached, and the attachment work of the shaft 38 becomes easy.

And have. With this configuration, since the movement of the spring 36 being pushed forward is suppressed, the contact of the coil portion 36c of the spring 36 with the shaft 38 is suppressed, and the opening / closing torque at the time of opening / closing the lid 3 can be reduced.

According to the washing machine 1 in the embodiment, the reinforcing member 42 includes a left regulating portion 43b that regulates the left movement of the first spring end portion 36a and a right regulating portion 43c that regulates the right movement. .. As a result, the first spring end portion 36a is positioned in the left-right direction, so that the first spring end portion 36a is prevented from falling off in the left-right direction, and the spring 36 moves left and right when the shaft 38 is attached. Since this can be suppressed, the work of attaching the shaft 38 becomes easy.

According to the washing machine 1 in the embodiment, the position where the first spring end portion 36a abuts on the rear regulating portion 43a and the position where the first spring end portion 36a abuts on the front regulating portion 43d are different. As a result, there is a difference in distance between the position where the first spring end portion 36a abuts on the rear regulating portion 43a and the position where the first spring end portion 36a abuts on the front regulating portion 43d. , The movement of the spring 36 pushing the spring 36 forward by its urging force can be effectively suppressed.

According to the washing machine 1 in the embodiment, it is a regulation unit of either the front regulation unit 43d or the rear regulation unit 43a, and the left regulation unit 43b or the right regulation unit 43c is on the side far away from the coil unit 36c. At least one of these regulatory parts can be provided.

If the left regulation portion 43b and the right regulation portion 43c are arranged in the lower folded portion 42f, that is, the hole portion 42d, which is the regulation portion on the near side, the movements of the front side, the right side, and the left side on the side closer to the coil portion 36c are generated. Since it is regulated, it becomes difficult to insert the first spring end portion 36a. On the other hand, when one of the left regulation portion 43b or the right regulation portion 43c is arranged in the upper folded portion 42e which is the regulation portion on the far side, the regulation in the hole portion 42d which is the regulation portion on the near side is regulated by the left regulation portion. Only one of 43b or the right regulation part 43c. Therefore, the hole portion 42d can be formed to be larger in the left-right direction by that amount, and the work of attaching the spring 36 becomes easier. Further, when the left regulation unit 43b and the right regulation unit 43c are arranged in the far side regulation unit, it is not necessary to provide the left regulation unit 43b and the right regulation unit 43c in the hole portion 42d which is the near side regulation unit. .. Therefore, the hole portion 42d can be formed larger in the left-right direction, and the work of attaching the spring 36 becomes easier.

According to the washing machine 1 in the embodiment, either the front regulation portion 43d or the rear regulation portion 43a far away from the coil portion 36c is formed in the upper folded portion 42e of the reinforcing member 42. As a result, the first regulating portion 43 including the rear regulating portion 43a and the front regulating portion 43d can be provided on the same reinforcing member 42, so that the reinforcing member 42 can be easily processed, the strength can be improved, and further assembly can be performed. Sometimes the positioning of the first spring end 36a becomes easy.
