PROBLEM TO BE SOLVED: To provide a washing machine enabling a user to safely and securely execute appropriate countermeasures by conducting an operation stop or an alarm output through an abnormal state at an occurrence of abnormality of a tub tilting device. SOLUTION: When a control part 71 activates a load drive circuit 72, a drive mechanism 31 rotates a working gear 32. Thereby a male screw 34 mating with a female screw of the gear 32 up/down acts to shift the hanging rod 4 in the same directions. Adjusting a rotational angle of the gear 32 to each of a plurality of the rods 4 inclines a water tub 5 hung by the rods 4. With rotations of the gear 32, pulse signals having the number corresponding to the rotational angle and generated by a magnet and a hole IC provided on the gear 32 are sent to the control part 71 via a pulse sensing circuit 74. The control part 71, when receiving no pulses from the sensing means even though activating the drive circuit 72 to shift the rods 4 in a target direction, judges the occurrence of the abnormality to conduct the operation stop or the alarm output.
