Abstract
A regenerative braking coordination device has a braking operating member receiving an input from a driver in the form of an operation amount, an input shaft operable for transmitting the operation amount, and a braking force boosting device operable to generate a hydraulic braking pressure corresponding to the operation amount transmitted by the input shaft. The device further includes a hydraulic pressure braking device to generate a braking force and an operation amount absorber for absorbing the operation amount of the input shaft. The operation amount absorber includes a cylinder, a piston dividing the interior of the cylinder into first and second hydraulic chambers and an orifice connecting the first and second hydraulic chambers. The orifice can be in the piston or in a flow channel.
