The present invention relates to an air pressure massager. The air pressure massager according to the present invention comprises: a cylinder； a piston vertically reciprocating inside the cylinder； a main hose connected to the cylinder so as to be a passage for supplying and recovering air by the vertical reciprocation of the piston； a valve connected to the main hose so as to open and close the supply of air pressure； an air bag connected to the valve so as to perform an acupressure function by using the transferred air pressure； and a driving part for providing rotational power, and further includes: a rotary shaft coupled to the driving part； a first eccentric cam coupled to the rotary shaft； a first press bar of which the upper end portion comes into contact with the lower end portion of the first eccentric cam and of which the lower end portion is coupled to the upper end portion of the piston； a second eccentric cam coupled to the rotary shaft； a second press bar of which the lower end portion comes into contact with the upper end portion of the second eccentric cam； and a link for connecting the first press bar and the second press bar. The air pressure massager is configured such that when the first press bar moves downward by the eccentric rotation of the first eccentric cam, the second press bar connected to the first press bar by the link also moves downward, and when the second press bar moves upward by the eccentric rotation of the second eccentric cam, the first press bar connected to the second press bar by the link also moves upward.
