Abstract
A centrifugal compressor includes: an impeller including a main body portion and a plurality of blades provided on an outer peripheral surface of the main body portion; an intake flow path facing the impeller in a rotational axis direction; and a throttling mechanism including a throttling member provided in the intake flow path, a ratio obtained by dividing a distance between an outer peripheral end of a leading edge of the blade and the throttling member by a maximum protruding height of the throttling member protruding from an inner wall surface of the intake flow path is equal to or less than 4.
