FIELD: automotive industry; automobile brake systems.
SUBSTANCE: invention relates to pumps used in brake systems of automobiles furnished with pneumatic boosters. Proposed rotor has blade holder, at least, one blade and drive member to transmit torque to blade holder. Intermediate member is arranged in places of force transmission between drive member and blade holder. Said intermediate member is fixed in radial direction relative to blade holder, being made of material resistant to friction wear caused by movement of drive member relative to blade holder. Intermediate member is provided with two parallel lugs connected by plate and arranged square to plane of plate to transmit torque to holder from side of drive member.
