座金及び座金付き締め具
Document Type and Number:
Japanese Patent JP4834313
Kind Code:
B2
Abstract:
A washer (1) has a body (2) having an axis (A1) and provided with a first face surface (3) located at one axial side and adapted to cooperate with a nut (10), a second face surface (4) located at an opposite axial side and adapted to cooperate with an object (19, 19') to be assembled or disassembled, and at least one additional turning resistant surface (5) adapted to cooperate with a bolt (12), the additional turning resistant surface of the body (2) being formed as a frictional surface providing a friction between the body and the bolt to frictionally impede the bolt (12) from turning and at the same to allow the bolt to be displaced in an axial direction when the nut (10) is turned. The second face surface (4) of the body (2) is formed to provide a friction between the body and the object (19') and therefore to impede the body (2) from turning, and the first face surface (3) of the body is formed with a smaller frictional characteristic than the second face surface (4) of the body (2) to at least reduce dragging of the body into turning by the turning nut (10). A fastener is provided with such a washer (1).
