Claims

[Scope of utility model registration request]

A shaft 36, which is a rotation shaft, is installed along the rotation axis of a grip part 30 having a recess 32 formed by recessing the door lock knob 2 etc. so that it can be gripped, and a flange-like support flange 39 is integrally attached to the shaft 36. A rotary drive shaft 50 is mounted so as to be rotatably supported in the inner hole 43 of the drive shaft socket 42 in the mounting portion 31 which is provided and rotationally driven via a ball bearing 40, and is gripped by the chuck 51 of the power tool. A support flange 45 facing the support flange 39 is installed in the drive shaft socket 42 erected along the rotation axis, and a compression coil spring 48 is installed between the support flange 39 and the support flange 45. Rotary drive shaft 5
Rotating force is transmitted between the mounting part 31 and the grip part 30 by the friction of the compression coil spring 48 by rotationally driving the door lock knob 2 with a work tool or the like, and the grip part 30 is rotated by the door lock knob 2.
When a rotational load of more than a predetermined value is received from, for example, the compression coil spring 48 slips between the support flange 39 and the support flange 45 via the drive shaft socket 42, causing both of them to idle. A tightening device for a door lock knob, etc., characterized in that the grip portion 30 is not rotated with a driving force exceeding a required value.
