Abstract
A vacuum type brake booster device comprising a booster shell divided into front and rear halves, a booster piston accommodated in the booster shell, and tie rods extending through the booster piston for connection of the front and rear halves. The tie rod is firmly held upright at a prescribed position on the rear half wall by the combined action of a mounting support on the rear half wall, a stepped tie rod flange, an elastic sealing member disposed in said mounting support between the rear half wall and the stepped flange, a retainer ring inside the mounting support. Accordingly, the tie rod thus firmly secured to the rear half is readily aligned with and pass through a through hole in the front half to expedite the assembly of the front and rear halves and, in addition, use of the elastic sealing member contributes to the simplification of the construction.
