Claim Text:
1. A vehicle body attachment structure for an electric brake actuator for a vehicle brake system including an input device to which braking operation by an operator is input and an electric brake actuator for generating a hydraulic brake pressure, based on at least an electric signal according to the braking operation, wherein the electric brake actuator includes: an electric motor that drives, based on the electric signal; a driving force transmission section for transmitting a driving force of the electric motor; and a cylinder mechanism for applying a pressure to brake fluid by moving a piston along an axial direction by the driving force transmitted from the driving force transmission section, wherein a mount portion for attaching the electric brake actuator to a vehicle body is provided in a vicinity of a center of gravity of the electric brake actuator; wherein: the electric brake actuator is provided with a penetration hole penetrating along a direction substantially perpendicular to an axial line of the cylinder mechanism, the electric brake actuator is supported by a fixing member penetrating through the penetration hole; a first boss portion is provided at one end portion along an axial direction of the penetration hole; a second boss portion is provided at another end portion along the axial direction of the penetration hole; and a third boss portion is provided along a vertical downward direction perpendicular to the axial line of the penetration hole, and wherein the electric brake actuator is supported at three points formed by the first to third boss portions.
