PROBLEM TO BE SOLVED: To solve problems in a method of preventing side slip in fixing an object, such as occurrence of fatigue failure causing a serious accident when a bolt is fastened hard and an increased fastening torque exceeds the limit, an easier design to increase gaps of holes to avoid the increased difficulty of designing and processing to increase positions of holes of an object and the precision of the hole diameter, and occurrence of displacement of the holes of the object because of unexpected external force even if the holes are fixed at appropriate positions with gaps. SOLUTION: A plurality of projected portions 6 and 7 each having a triangle shape in section are formed on surfaces that are in contact with a hole or a cut-out of objects 1 and 2 processed to be fixed, in a manner that the objects 1 and 2 pass through a connecting member 3 for pinch and contact. The portions 6 and 7 incline toward the center of the connecting member 3 whose portion in the direction to prevent side slip is taken as a base. COPYRIGHT: (C)2004,JPO
