PROBLEM TO BE SOLVED: To provide a centrifugal force applying device capable of automatically altering the angle-of-rotation position of a microchip, and a specimen liquid analyzer. SOLUTION: The centrifugal force applying device 2 which constitutes the specimen liquid analyzer 100 includes a rotary stand driving force transmission mechanism 27 for applying rotational driving force to a chip rotary stand 23 and a rotary stand rotating mechanism 25, and the transmission part 25c of the rotary stand rotating mechanism 25 is pushed up by rectilinearly advancing and moving the pusher 27g of the rotary stand driving force transmission mechanism 27 to transmit moving force in an upward direction to a cam 25a having upper and lower end cam surfaces having a plurality of inclined surfaces formed thereto. Moving force in a lower direction is applied to the cam 25a by the restoring force of a coil spring 25f. The rotary direction due to twist force at the time of contraction in the winding direction of the coil spring 25f is equal to the winding direction of the coil spring 25f and the rotary direction at the time of restoration from the contracted state of the coil spring 25f and the direction reverse to the winding direction of the coil spring 25f become the same.
