Abstract: An air pressure adjusting device includes a supplying device and a reception circuit configured to receive a detection signal that includes information indicating an air pressure of a tire. The supplying device includes a piston that supplies air to the tire by being moved by rotation of the tire. The air pressure adjusting device includes a switching unit and a controller. The switching unit is configured to be switched between a first state, in which the switching unit allows movement of the piston, and a second state, in which the switching unit prohibits movement of the piston. The controller is configured to control the switching unit. The controller is configured to obtain the information indicating the air pressure of the tire from the detection signal received by the reception circuit, switch the switching unit to the second state when the air pressure of the tire is greater than or equal to a threshold, and switch the switching unit to the first state when the air pressure of the tire is less than the threshold.
