<P>PROBLEM TO BE SOLVED: To enhance reactivity when more stepping force is applied by instantaneously applying oil pressure higher than in automatic braking control execution to a secondary master cylinder in response to stepping force increasing operation during the automatic braking control execution in a vehicular braking device provided with a first opening/closing valve between an oil pressure generating source and an input hydraulic chamber of the secondary cylinder and a second opening/closing valve between a booster hydraulic chamber and the input hydraulic chamber of the secondary master cylinder. <P>SOLUTION: A one-way valve 125 allowing communication of brake fluid from a booster hydraulic chamber 59 side to an input hydraulic chamber 92F side is connected in parallel with a second opening/closing valve 124. <P>COPYRIGHT: (C)2003,JPO |
