Original Abstract Submitted

Disclosed is a fluid pressure supply apparatus. The fluid pressure supply apparatus may include a motor including a stator and a rotor, a motion conversion device which converts a rotational motion of the rotor into a linear motion, a piston which is connected to the motion conversion device and performs a linear motion, a housing which includes a cylinder, in which the piston is disposed to perform the linear motion, and a guide extending in a longitudinal direction of the cylinder and inserted into the piston and in which a fluid pressed by the piston is disposed in a space between an inner circumferential surface of the cylinder and an outer circumferential surface of 10 the guide, a first magnet disposed on the piston, and a first magnet sensor which is disposed on the guide and detects a change in a magnetic field of the first magnet according to the linear motion of the piston.
