Title:
DYNAMIC DAMPER
Document Type and Number:
Japanese Patent JP2012225487
Kind Code:
A
Abstract:

To provide a dynamic damper, in which movability of a movable member is not disturbed, and a rolling element can be reliably fixed.

The dynamic damper is equipped with a body part 32 in which a rolling chamber 40 is formed, the rolling elements 42 which are accommodated in the rolling chamber 40 and roll in the rolling chamber 40, and the movable member 35 which presses the rolling elements 42 in a direction parallel with the rotational center axis of the rolling elements 42 and thereby pushes to the inner side face of the body part 32 facing the surface of the rolling elements 42 facing the body part so as to fix the rolling elements 42. The movable member 35 is composed of a pressing part 36 contacting with the side faces of the rolling elements 42 and a shaft part 37 to make the pressing part 36 movable, and the pressing part 36 is covered with the body part 32 and accommodated in the rolling chamber and is shaped as having a gap with respect to the radially directed surface of the rolling chamber 40. The shaft part 37 is exposed to outside the rolling chamber, while the rolling chamber 40 is a closed space formed from the body part 32 and the shaft part 37, and is arranged in oil filled in a torque converter.
