PURPOSE: To improve the durability of a vane type air pump, by making up a vane from the phenol resin contained with a filler having lubrication and reinforcement capacity, while molding a seal member being coherent to both sides of the vane, from a carbon system material impregnated with phenol resin.

CONSTITUTION: On the peripheral wall of a rotor 3, three long holes 7 are formed in parallel with its rotating center line, and a vane 8 is pierced into each long hole. At both side parts of each long hole, a seal member 10 being coherent to the vane 8 is installed. The vane 8 is made up by mixing a filler, which has the residual of lubrication and reinforcement capacity, with 50W60% phenol resin, while the seal member 10 is formed up by way of molding and sintering processes after having graphite powder carrying lubrication capacity impregnated with the phenol resin so that durability in the seal member and the vane as well as durability in a vane type air pump in turn are all improved.
