The outer side of the) means.

Hereinafter, the port surface 81a1 and the support surface 81a2 of the first upper port section 81a will be referred to as the first upper port surface 81a1 and the first support surface 81a2, respectively, and the second upper port section 82a will be described. The port surface 82a1 and the support surface 82a2 of the () are referred to as the second upper port surface 82a1 and the second support surface 82a2, respectively.

In the first balancer 91, the first position limiting portion 91p may contact the first support surface 81a2. Alternatively, in the first balancer 91, the gap between the first position limiting portion 91p and the first support surface 81a2 is such that the first upper discharge port 83a is inserted into the first upper port insertion tube 63a. It may be arranged shorter than the length (L).

The first support surface 81a2 may be in contact with the first position limiting portion 91p. Alternatively, the first support surface 81a2 is spaced apart from the first position limiting portion 91p, and the spaced interval is the length L in which the first upper discharge port 83a is inserted into the first upper port insertion tube 63a.

May be shorter than

Therefore, the problem that the upper discharge ports 83a and 84a are detached from the upper port insertion pipes 63a and 64a can be prevented.

The balancer 90 may be disposed outside the gasket bodies 61 and 62, and an inner surface of the balancer 90 may be concave to cover a portion of the outer circumferential surface 61 of the gasket body. The first balancer 91 may surround a portion of the first region, and the second balancer 92 may surround a portion of the second region. The first and second position limiting portions 91p and 92p are provided at positions corresponding to the first and second upper discharge ports 83a and 84a, respectively, and the first and second upper discharge ports 83a and 84a are formed of a gasket body ( 61, 62 is disposed higher than the center (O). Therefore, the inner surfaces of the first and second position limiting portions 91p and 92p may be inclined in a direction away from the vertical line OV passing through the center O of the gasket bodies 61 and 62 from the upper side to the lower side.

The first support surface 81a2 which is the outer surface of the first upper port section 81a and the inner surface of the first position limiting portion 91p face each other, and the second surface that is the outer surface of the second upper port section 82a. The inner surface of the support surface 82a2 and the second position limiting portion 92p oppose each other. Therefore, the first and second support surfaces 81a2 and 82a2 may be inclined in a direction away from the vertical line OV as the upper side goes to the lower side.

Meanwhile, the first position limiting portion 91p may include protrusions protruding toward the first upper port sections 81a and 82a or the gasket bodies 61 and 62 on the inner side.

It inclines and the inner surface of the 2nd support surface 82a2 and the 2nd position limiting part 92p inclines in the same direction. Therefore, the balancer 90 stably supports the distribution pipe 80 and can prevent the distribution pipe 80 from being removed from the gasket 60.

On the other hand, the balancer (90) has the advantage of preventing the removal of the distribution pipe 80 when using the washing machine, if the repair of the washing machine is necessary, it may cause difficulty in separating the distribution pipe (80) from the gasket (60). .

The lower discharge ports 83b and 84b are located below the upper discharge ports 83a and 84a, and are located in a direction in which the upper ends of the first and second pipe sections 81 and 82 are separated from each other by the position limiting portions 91p and 92p. Opening is prevented, so even if the lower port sections 81b and 82b are not supported by the balancer 90, the possibility that the lower discharge ports 83b and 84b are removed from the lower port insertion pipes 63b and 64b is very low. Therefore, the balancer 90 may be disposed such that the inner surface of the balancer is spaced apart from the outer surface of the lower port sections 81b and 82b.

An interval between the lower port sections 81b and 82b and the balancer 90 may be greater than an interval between the upper port sections 81a and 82a and the balancer 90. That is, the distance between the outer surface of the first lower port section 81b and the inner surface of the first balancer 91 may be greater than the interval between the first support surface 81a2 and the first position limiting portion 91p. The distance between the outer surface of the second lower port section 82b and the inner surface of the second balancer 92 may be greater than the distance between the second support surface 82a2 and the second position limiting portion 92p.

In addition, the gasket 60 is formed of a flexible material, so that the interval between the lower port sections 83b and 84b and the balancer 90 is inserted into the lower port insertion pipes 63b and 84b. Even if the length is slightly smaller than that, the lower discharge ports 83b and 84b can be artificially separated from the lower port insertion pipes 63b and 64b.

Therefore, during repair of the washing machine, the upper discharge port is easily removed after separating the lower discharge ports 83b and 84b from the lower port insertion pipes 63b and 64b without removing the balancer 90 from the tub 30. 83a and 84a can be separated from the upper port insertion tubes 63a and 64a.

It is bent in the direction away from the gasket bodies 61 and 62. At least a portion of the upper port section 810a may be located in the assembly space AS. For reference, in FIG. 23, P1 denotes a curve forming the upper guide section 810d, and P2 denotes a shape in which the upper port section 810a is bent from the upper guide section 810d.

The upper guide section 810d may be located at an outer lower portion of the assembly space AS. The position limiting portion 91p of the first balancer 93 is an assembly space between the upper portion of the gasket bodies 61 and 62 (that is, the portion belonging to the upper semicircle with respect to the center O of the gasket body). (AS) may be specified. At this time, the assembly space AS is opened by the gap G between the lower end of the first balancer 93 and the gasket bodies 61 and 62, and the upper guide section 810d passes through the opened portion from the lower side. Thus, the upper port section 810a may be drawn into the assembly space AS.

Meanwhile, the upper discharge port 83a may extend in the horizontal direction from the upper port section, and the first balancer 93 may extend to a lower side than the upper discharge port 83a. Specifically, in the first balancer 93, the lower end of the position limiting portion 91p defining the assembly space AS extends further to the lower side than the upper discharge port 83a.
