according to the present embodiment are approximately halves of those of the vibrations in the conventional washing machine 60 at the initial stages of the dehydrating operations hereinafter modified embodiments of the present invention will be described with reference to fig6 through 10 referring to fig5 a washing machine 30 according to a second embodiment of the present invention includes the same elements as in the washing machine 1 according to the first embodiment shown in fig1 and 2 however a suspension unit 31 of the present embodiment has a modified structure compared with the suspension unit 11 in fig1 and 2 that is the suspension unit 31 of the present embodiment has a single suspension bar 13 with respect to a pair of dampers 15 the suspension bar 13 has at the lower end thereof a t shaped joint 33 having two opposite forks as shown in fig6 a pair of elbow shaped rods 35 are fitted in the two forks of the joint 33 respectively the dampers 15 are combined with the lower ends of the rods 35 respectively fig7 is a graph for explaining vibrations at initial stages of dehydrating operations in the washing machine 30 in fig5 and the conventional washing machine 60 respectively as can be seen in fig7 the amplitude of the vibration in the washing machine 30 according to the present embodiment is approximately half of that of the conventional washing machine therefore the spring constant of the.
