Abstract: A vehicle brake device includes a hydraulic pressure generating device, a valve device, a pump and an accumulation section forming an accumulation chamber connected to a fluid passage between the valve device and the hydraulic pressure generating device or to a master chamber. A dead band is set in which the change of force of the magnitude corresponding to the hydraulic pressure in the master chamber does not substantially act on a brake operating member. A characteristic representing the relation between the pressure and the brake fluid quantity in the accumulation chamber is set based on a characteristic representing the relation between the pressure and the brake fluid quantity in a wheel cylinder and the dead band so that, when brake fluid is flowing into and from the accumulation chamber, a force of the magnitude corresponding to the master chamber hydraulic pressure does not act on the brake operating member.

Abstract: A liquid pressure control device includes a deformable part positioned in a deformed state between a housing and a case in an assembled state in which the housing and the case are assembled. When a first load is applied to the deformable part in a non-assembled state in which the case is separated further from the housing in a first direction than in the assembled state, the deformable part can place the housing and the case in a separation state in which a second end portion supported by a bottom wall is separated from a terminal in the first direction. When a second load greater than the first load is applied in the non-assembled state, the deformable part is deformed by the second load and can place the housing and the case in a contact state in which the second end portion and the terminal contact each other.

Abstract translation: 车辆制动装置包括液压产生装置，阀装置，泵和形成与阀装置和液压产生装置之间的流体通道连接到主室的蓄积室的积存部。 设定死区，其中与主室中的液压相对应的大小的力的变化基本上不作用在制动操作构件上。 基于代表轮缸中的压力和制动液量与死区之间的关系的特性来设定代表蓄积室中的压力和制动液量之间的关系的特性，使得当制动液流动时 进入和离开积聚室，与主室液压相对应的大小的力不作用在制动操作构件上。
