Claims

[Scope of utility model registration request]

One hole of the cylindrical chuck body is provided with an annular inner groove along the circumferential direction, and an outer groove is also provided on the outside of the chuck body concentrically with the inner groove, and these inner grooves and outer grooves are At least two or more communication holes are provided so as to communicate with each other in a point-symmetrical position with respect to the cross-sectional center position of the chuck body, and through these communication holes, the circumference near the tip is provided in the hole portion. A cylinder having a proximal end portion of a rod-shaped elastic material protruding into the inner groove such that its surface is exposed is fitted into the outer groove, and further has an inner diameter equal to the outer diameter of the chuck body at the position where the outer groove is provided. A chuck device characterized in that the base end portion of the elastic material is held in the outer groove by fitting the body into the chuck body.
