Abstract
A housing assembly for a tandem brake booster comprises a front shell, a rear shell coupled at its outer peripheral rim within an annular stepped flange of the front shell, and a partition wall member assembled within the front shell to subdivide the interior of the coupled shells into two chambers and having an annular radial flange interposed between an annular shoulder of the stepped flange and the outer peripheral rim of the rear shell. The annular stepped flange is formed with a plurality of circumferentially spaced radial projections engaged with the outer peripheral rim of the rear shell. The outer peripheral rim of the rear shell and the annular radial flange of the partition wall member each are formed with a plurality of circumferentially spaced radial recesses which are arranged to permit removal of the rear shell and the partition wall member from the front shell when opposed to the corresponding radial projections of the front shell. The outer peripheral rim of the rear shell is further formed with a second radial recess the inner end of which is radially inwardly spaced from the radial projections of the front shell, and the partition wall member is further formed with an axial projection engaged with the second recess of the rear shell to be radially inwardly spaced from the radial projections of the front shell.
