20150144420 | ACOUSTIC EQUIPMENT - A distal end of an inserted pole makes contact with a bottom surface or tapering surface of a portion corresponding to a bottom of an insertion hole. A lever rotates about a pivot shaft, and a pressing surface facing from a recessed portion formed in the insertion hole presses a side surface portion of the pole. The pole pressed by the pressing surface is mainly received by ridge portions, particularly the ridge portions positioned on the opposite side with a central axis therebetween in relation to the pressing surface. The ridge portions are positioned on both sides of the pole with the cross section along the line A-A therebetween as viewed in the axial direction. As the lever is rotatably operated in the tightening direction, the pressing position gradually approaches the central axis, thereby increasing the pressing force. | 05-28-2015 |
