Abstract
A clamping member fastenable to a bolt, wherein the clamping member includes a bowl-shaped main body having a bolt-inserting opening formed through a bottom center portion thereof. A leaf spring clip is embedded integratedly in the bottom center portion of the bowl-shaped main body. The leaf spring clip includes a plurality of spring claws extending from a periphery of the bolt-inserting opening toward a center of the bolt-inserting opening in an oblique and upward direction. The plurality of spring claws are engagable with a bolt and fasten the clamping member to the bolt responsive to a direct pushing action of the main body of the clamping member over the bolt with the bolt passing through the bolt-inserting opening, without requiring any tools or rotating action of the clamping member relative to the bolt. The bolt has a thread thereon and the thread may have an upper surface portion formed into a convexly arched surface and a lower surface portion formed into a concavely arched surface, the thread being engagable with the plurality of spring claws such that the spring claws engage over the convexly arched upper surface portion of the thread of the bolt responsive to a direct pushing action of the main body of the clamping member over the bolt.
