A patient transfer apparatus of the present invention is configured in that a top movable board of a patient movable bed is easily movable onto a patient bed mattress by using a transfer arm and a wheeled chassis moving on the transfer arm, so as to cause minimum inconveniences to a patient and allow for a transfer with ease when the patient who is not able to move freely is transferred between the patient bed and the patient movable bed. In addition, a linkage device is installed beneath the top movable board to easily incline the top movable board toward the body of the patient. Therefore, the patient can be taken onto or removed from the patient movable bed merely by lying on his/her side from the posture of lying on his/her back, thereby minimizing inconvenience to the patient caused by a patient transfer, and enabling the patient transfer to be easily performed with a smaller number of people. Further, the patient transfer apparatus of the present invention eliminates the necessity of external power source for patient transfer, and has the advantages of a simple configuration and reduced cost.
