An air flow adjusting apparatus includes first, second, and third air passages, and a flow adjusting plate. The first air passage is to be connected to a load. The second air passage is to be connected to an atmosphere. The third air passage is to be connected to an air source and branches to be connected to the first and second air passages. The flow adjusting plate opens/closes a first connecting portion between the first and third air passages and a second connecting portion between the second and third air passages in an interlocked manner. The flow adjusting plate opens/closes the first and second connecting portions with a sum of opening areas of the first and second connecting portions being always set constant.
