PROBLEM TO BE SOLVED: To provide a share pump which can compress an adhesive fluid to a pressure chamber adequately according to the rotation number of a feed disk, not depending on the temperature of the adhesive fluid. SOLUTION: In this share pump, an adhesive fluid in a fluid feeding groove 16 on a pump disk 48 which is contacted to a feed disk 9 is rotated together in the rotating direction of the feed disk 9, by the rotating behavior of the feed disk 9 in a pressure chamber 10, in the relative rotation time of the first and the second rotary members 2, (3), and the adhesive fluid is compressed into the pressure chamber 10 so as to drive a piston. In such a share pump, a volume variable part 50 to increase the groove cross section area following to the temperature reduction is provided to the fluid feeding groove 16 of the pump disk 48, and the compression flow rate increase part following to the temperature reduction of the adhesive fluid is absorbed by the increase of the groove cross section area of the volume variable part 50 following to the temperature reduction of the adhesive fluid, and the actual feeding flow rate to the pressure chamber 10 is regulated into an adequate value according to the rotation of the feed disk 9.
