ABSTRACT:
An improvement of a booster as may be used in a brake of an automobile is provided. The booster is provided with pseudo-reaction imparting means (spring) which imparts a pseudo-reaction which depends on the travel of an input shaft to the input shaft. An arrangement is made in accordance with the invention such that when an input applied to the input shaft exceeds a given value, only the pseudo-reaction from the pseudo-reaction imparting means (spring) is transmitted to a driver. The arrangement enables an increased output to be reliably obtained, even by a powerless female driver, whenever a braking force of an increased magnitude is required as when using the booster as an emergency brake.
