ことができる。According to the above embodiment, the bottom member 10 is made of synthetic resin. Therefore, the cost of the rotary tank 8 is reduced compared to the conventional case where the bottom member is made of stainless steel. Moreover, since the degree of freedom in designing the bottom member 10 is improved, it is possible to reliably seal the both by a simple configuration in which the packing 13 is sandwiched between the body portion 9 and the bottom member 10.

るため、シールが一層安定する。When the bottom member 10 is sandwiched between the ridge 9a and the caulking protrusion 9b of the body 9, the packing 13 is attached to the upper end of the connecting portion. Therefore, the pressing force acting on the bottom member 10 from the protruding portion 9a is transmitted to the packing 13, and the packing 13 is reliably held in the elastically deformed state, so that stable sealing performance is obtained. With this,
Due to the difference in shrinkage that occurs when different materials such as stainless steel and synthetic resin are combined, the packing 13 is not attached to the portion where the difference in dimension shrinkage is large, but the difference in dimension shrinkage is small by attaching it to the upper end of the caulking. Since it can be sealed in parts, the seal is more stable.

向上する。Further, the bottom member 10 was press fitted into the inner peripheral surface of the body portion 9. Therefore, even if there is a difference in shrinkage amount between the body portion 9 and the bottom member 10 due to a temperature change or the like, since the two are held in close contact with each other, the watertightness is improved. The body 9 was formed by welding the ends of the stainless steel plate. Therefore, it is possible to eliminate the overlapping portion such as in the case where the end portions of the stainless steel plates are overlapped and caulked, so that the strength and weight balance of the body portion 9 are improved. At the same time, when caulking the lower end portion of the body portion 9 to the bottom member 10, it becomes difficult to form a gap between them, so that the watertightness is improved.

ルできる。As is apparent from the above description, the rotary tub of the combined washing machine of the present invention has the following effects. According to the means described in claim 1, the bottom member is made of synthetic resin. Therefore, the cost of the rotary tank is reduced as compared with the conventional case where the bottom member is made of stainless steel. With this,
Since the degree of freedom in designing the bottom member is improved, the bottom member and the tubular member can be reliably sealed with a simple configuration. According to the means described in claim 2, both can be reliably sealed with a simple structure in which the seal member is simply sandwiched between the tubular member and the bottom member.

できる。According to the third aspect of the invention, when the bottom member is sandwiched between the two sandwiching portions of the tubular member, the seal member is attached to at least one of the upper end portion and the lower end portion of the connecting portion. Therefore, the pressing force acting on the bottom member from the sandwiching portion of the tubular member is efficiently transmitted to the seal member, so that the seal member is reliably held in the elastically deformed state, and as a result, stable sealing performance is obtained. According to the means described in claim 4, the protrusion formed on one of the tubular member and the bottom member is inserted into the hole formed on the other. Therefore, the engagement between the protrusion and the hole can restrict the movement of the bottom member due to the difference in contraction rate.

度および重量バランスが向上する。According to the means described in claim 5, the bottom member is press-fitted into the inner peripheral surface of the cylindrical member. Therefore, even if there is a difference in shrinkage amount between the tubular member and the bottom member, they are kept in close contact with each other, and as a result, the watertightness is improved. According to the means described in claim 6, when the upper end of the bottom member is fitted to the lower end of the tubular member, at least one of them is tapered. Therefore, it becomes easy to fit the upper end of the bottom member to the lower end of the tubular member. According to the means described in claim 7, in forming the tubular member, the end portions of the stainless plate are welded.
For this reason, since the overlapping portion can be eliminated, the strength and weight balance of the tubular member are improved.
