摘要： To provide a practical chuck device which is not only capable of providing more reliable and stable retention between the rotary body or the main body and the rotary sleeve, but also has excellent mass-productivity. A chuck device in which a rotary sleeve (2) provided to a main body (1) is rotated, and by the rotation of an annular rotary body (3) which rotates together with the rotary sleeve (2), jaws (4) which are screwed together with the rotary body (3) are expanded, contracted, advanced, and retracted, and a tool is gripped by the jaws (4); the chuck device comprising a retaining engaging body (5) for engaging with the rotary body (3) or the main body (1) and preventing the rotary sleeve (2) from coming out of the rotary body (3) or the main body (1); wherein the retaining engaging body (5) is provided so as to be fixed to a proximal end side of the rotary sleeve (2); a rotation transmission part for directly or indirectly transmitting the rotation of the rotary sleeve (2) to the rotary body (3) is provided to the retaining engaging body (5); and the rotation of the rotary sleeve (2) is transmitted to the rotary body (3) via the retaining engaging body (5), and the rotary body (3) rotates together with the rotary sleeve (2).
