置。The interior of the housing is divided into a front chamber and a rear chamber that are always under negative pressure by a power piston and a diaphragm that is airtightly fixed to the power piston and the housing, respectively, and the power piston is airtightly connected to the rear wall of the housing. a large slidably extending cylindrical portion having a control valve mechanism actuated by a pushrod attached to the pedal to control communication between the rear chamber, the front chamber and the atmosphere; In a negative pressure booster incorporating a biasing mechanism that biases a valve plunger connected to the front end of the push rod in the control valve mechanism rearward, the biasing mechanism includes: a disc spring having an annular outer periphery that abuts the receiving portion of the power piston from the rear and has a finger-shaped portion on the inner periphery of the annular outer periphery; Consisting of a retainer having a spherical surface centered on the center of swing at the front end, and a cylindrical member slidably abutting the spherical surface of the retainer from the front and receiving the fingers of the disc spring from the rear. Negative pressure booster.
