A hinge assembly for joining a cover to a main body of a foldable device includes a hollow housing ( 10 ), a spring ( 20 ), a shaft ( 30 ), and a positioning pin ( 40 ). The housing includes an open end, an opposite rear end ( 11 ). The spring is received in the housing. The shaft includes a cam portion ( 34 ) received in the housing, and a shaft portion ( 32 ) passing through the spring and extending out through the rear end. One end of the spring biases the cam portion, and an opposite end of the spring biases the rear end. The pin is transversely retained in the housing near the open end, and is rotatable relative to the shaft and movably engaged with a cam surface of the cam portion. When the rear end is urged in an axial direction by the spring, the cam surface causes the pin to rotate the housing.
