On the other hand, if an execution instruction is input (S21: Y), that is, if an operator such as an assistant presses any button of the input device 80, the control unit 91 determines that an alarm factor is present at that time.

Further, in the case of an alarm factor that the difference between the command position of the lifting / lowering actuator 71 and the current position exceeds a predetermined value when the posture of the person being assisted is not appropriate, the assistance device 1 is temporarily stopped. The alarm factor is eliminated.

Then, the assistant can cause the assistance device 1 to continue the assistance-related operation again without turning off the power of the assistance device 1.
  • the input device 80 is a device used when an instruction to perform assistance related operations of the assistance device 1 is issued. Therefore, the operator does not perform a special operation for releasing the alarm stop state.
