A patient transfer apparatus includes a transfer arm for moving a top movable board on which the body of the patient is supported； a transfer arm housing fixed on a patient-moving bed frame so as to move the transfer arm； and a side protector laid on a patient bed so as to serve as a guide rail for enabling the transfer arm to easily move over the patient bed. The patient transfer apparatus enables the patient to simply lie on his/her side from a recumbent position such that the patient can be loaded or unloaded onto/from the patient-moving bed, thus minimizing inconveniences to the patient and easily moving the patient with fewer staff members.
