PROBLEM TO BE SOLVED: To improve the strength against rotational deviation and torque even in a rotary anode that rotates at high speed. SOLUTION: A rotary type anode device 100 incorporated into an X-ray tube includes a rotation mechanism 110 having a driving shaft 112, and an anode member 120 having a fit hole into which this driving shaft 112 is fitted, wherein the above fit hole is formed to be rotationally asymmetric to the central axis of the above driving shaft.
