In the hole 59 of the upper receiving member 51, the hanging rod 39 is slightly pressed into a portion 60 radially smaller than the diameter D of the hanging rod 39, whereby the upper receiving member 51 is inserted into the hole 59. At 60, the hanging rod 39 is always in contact. In this state, the upper receiving member 51 moves together with the hanging rod 39 even if the hanging rod 39 bends or recovers as the outer tub 23 shakes.

The portion 60 radially smaller than the diameter D of the hanging rod 39 is
The entire inner peripheral portion of the hole 59 may be formed to protrude inward over the entire length. However, simply doing so causes the portion 60 to come into contact with the entire outer peripheral portion of the hanging bar 39 in a long range, making it difficult for the hanging bar 39 to be inserted into the upper receiving member 51, and assembling easiness. Will not be good.
