Document Type and Number:
Japanese Patent JPH04359820
Kind Code:
A
Abstract:
PURPOSE: To provide a small-sized control knob lock part which can be moved in the rotating direction and in the rectilinear direction. CONSTITUTION: A lock ring 40 is rotated clockwise on a mounting bush 60 to engage an internal thread of the lock ring 40 with the end part 62 of an outer thread of the mounting bush 60. The tapered thread of the lock ring 40 is gradually engaged with the tapered thread of the mounting bush 60, whereby the chamferred thread of the mounting bush 60 is engaged with the flat base end part of the lock ring 40 so that especially the fastening part in the annular wall part 68 moves inward radially. Accordingly, the lock ring 40 presses the fastening element 80 to the shaft part 26 of the control knob 20, thereby preventing radial and axial movement.
