Reception device

A reception device mounted on an operated object that is remotely controlled based on a control signal, comprising:

• a reception part configured to receive the control signal from a transmission device;
• and a controller configured to performs a process of outputting a motor driving instruction value corresponding to the control signal received by the reception part as a motor driving instruction value for controlling a driving amount of a motor,
• wherein the controller performs:
• a hold process for holding and outputting a value corresponding to the control signal during a reception period as the motor driving instruction value when the control signal is not receivable;
• and
• a failsafe gradual change process for gradually changing the motor driving instruction value from the value during the hold process toward a failsafe value determined for failsafe when a period of the hold process reaches a certain period,
• wherein the controller is configured to variably set a gradual change period by the failsafe gradual change process.
