PROBLEM TO BE SOLVED: To provide a dynamic vibration absorbing device having a simple structure, capable of dispensing with maintenance, facilitating mounting on a vibration object, and preventing occurrence of change with age, and having excellent damping performance of vibration. SOLUTION: This dynamic vibration absorbing device 1 has a shaft member 2 whose one end is attached to a vibration body O for suppressing vibration, in which an engaging part 5 is formed at the other end, and which has predetermined mass and a movable member 6 having an insertion hole 6a in which the shaft member 2 is inserted and an abutting face 6b whose one end face is held in the engaging part 5 and which is formed to abut on the shaft member 2 and have a predetermined clearance for the shaft member 2 at the inner periphery of the insertion hole 6a. The abutting face 6b of the movable member 6 repeats collision against the shaft member 2 by vibration of the vibration body O to absorb vibration of the vibration body O.
