PROBLEM TO BE SOLVED: To provide a continuous type centrifuge which continuously performs the solid-liquid separation of earth and sand water with a simple structure and capable of dealing with mud water supply of boring execution without requiring filters, etc. SOLUTION: A rotating body 6 internally formed with a closed vacant chamber 62 by matching of an upper bowl body 60 and a lower bowl body 61 is perpendicularly axially rotated by a pivoting rod 5. An injection port 50a and a drain hole 51a are respectively disposed at the top and bottom of the pivoting rod 5 in the closed vacant chamber and a spring up disk 52 is disposed at the middle thereof. An annular retaining chamber 64 segmented by annular opening/closing means 63 is formed on the peripheral part side in the closed vacant chamber. The opening/closing means is constituted to operate to partition the closed vacant chamber and the retaining chamber cooperatively with the vertical parting movement of both bowl bodies when the peripheral edge of the rotating body is opened by this movement. The opening and closing of the opening/closing means and the opening and closing of the peripheral edge of the rotating body are reversely interlocked, by which the solid contents are released from the peripheral edge at every deposition of the solid contents to the retaining chamber.
