Abstract: In a vacuum brake booster, a valve mechanism having a negative pressure valve which communicates and cuts off between a negative pressure chamber and a variable pressure chamber according to a retractable movement of the plunger with respect to a valve body, and an atmosphere valve which communicates and cuts off between the variable pressure chamber and the atmosphere is assembled in a shaft hole of a valve body. In addition, the plunger and the key member are assembled in the shaft hole. In addition, in the vacuum brake booster, when the valve body is in the forward moving position and the plunger is moved rearward from the forward moving position, a protrusion tilting and holding the key member with respect to the valve body is provided.
