Abstract

An electric braking device includes: a first valve unit for adjusting a first differential pressure between a master cylinder side liquid pressure and a wheel cylinder side liquid pressure; a storage unit forming a fluid storage chamber; second valve units for adjusting a second differential pressure between the master cylinder side liquid pressure and a storage chamber side liquid pressure; an electric pump for discharging the fluid in the storage chamber; and a control unit which, while operating the electric pump during a time from initiation of braking force application until a request value acquired by a request braking force acquiring unit reaches a maximum value, controls the first valve unit such that the first differential pressure becomes zero, and controls the second valve units such that the second differential pressure becomes zero.
