The invention provides a vacuum booster and an automobile, which relate to the technical field of automobiles. The vacuum booster comprises a shell and a diaphragm arranged in the shell, wherein the shell comprises an integrally formed step-shaped structure, and the step-shaped structure comprises a first wall, a second wall and a connecting surface for connecting the first wall and the second wall; the included angle between the connecting surface and the second wall is smaller than a first angle, and the surface of the diaphragm is attached to the inner wall of the included angle. Accordingto the scheme, the problem that the vacuum booster leaks due to the fact that the shell and the diaphragm in the vacuum booster are prone to wrinkling, flanging and disengaging in the assembling process can be solved, and the good sealing effect is achieved.

    本发明提供一种真空助力器及汽车,涉及汽车技术领域,所述真空助力器,包括:壳体,所述壳体包括一体成型的台阶状结构,所述台阶状结构包括第一壁、第二壁和连接所述第一壁和所述第二壁的连接面;设置于所述壳体内部的膜片;其中,所述连接面和所述第二壁的夹角小于第一角度,所述膜片的表面与所述夹角的内壁贴合。本发明的方案可解决真空助力器中的壳体与膜片在装配时易产生的褶皱、翻边以及脱出,从而造成真空助力器泄漏的问题,达到良好的密封效果。
