摘要： PROBLEM TO BE SOLVED: To provide a drive nut which can prevent any exterior of a cargo from being broken, and be easily driven, but not easily torque-driven when it is driven. SOLUTION: A flange 4 with an outer circumferential edge 11 chamfered in an arc is provided on an upper part of a nut body 1 with a female screw formed on an inner circumferential surface thereof, and a plurality of ridge- shaped projecting bars 14 for locking purpose are provided in a perpendicular direction downwardly from a bearing surface 13 of the flange 4 at specified intervals on an outer circumferential surface 12 of the nut body 1. Since no sharp edge is formed on the flange differently from a conventional nut, a packing material of the cargo is not hooked thereby. In addition, the ridge-shaped projecting bar 14 is not deformed, and a high tightening torque can be ensured.

摘要： PROBLEM TO BE SOLVED: To provide a bolt capable of maintaining an attitude of the same and fastening the same appropriately without generating trouble in fastening such as seizure even if the bolt is obliquely screwed in a nut. SOLUTION: The bolt includes a head part and a shaft part extending out from the head part. The shaft part includes a first fixed diameter column shaped part, a transition part, a column shaped connecting part, and a second fixed diameter column shaped part. The first fixed diameter column shaped part has a fixed first diameter along an axial direction and has thread ridges of a designated pitch formed on a side surface. The transition part has a tapered shape of which diameter gradually reduces as it separates from the head part along the axial direction, coaxially projects from a tip of the first fixed diameter column shaped part, and has thread ridges of a designated pitch formed on a side surface. The column shaped connecting part has a diameter smaller than the first diameter along the axial direction and coaxially projects from a tip of the transition part. The second fixed diameter column shaped part has a fixed second diameter smaller than the first diameter along the axial direction, coaxially projects from a tip of the column shaped connecting part, and has thread ridges of the designated pitch formed on a side surface. Tops of the thread ridges formed on the side surface of the transition part are cut out. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To provide a compact bolt capable of remarkably reducing the generation of seizure by forming the bolt so that it is normally screwed to a female screw member or idly turned. SOLUTION: In this bolt 1, length of a nearly conical tapered part 12 extended from a fixed diameter part 11 of a shaft part 10 is set in a range of 1-2 pitches of a screw part 20 formed in the periphery of the shaft part 10, and taper angle of the tapered part is set at nearly 60 degree. With this structure, range of angle of inclination wherein engagement of the bolt 1 with a nut 70 is formed as small as possible, and probability that the bolt 1 is normally driven to the nut 70 and probability that the bolt 1 is idly turned without being driven to the nut 70 are raised to remarkably reduce the generation of bite and seizure.

摘要： PROBLEM TO BE SOLVED: To provide a bolt which is hardly seized up and hardly strips threads even if the bolt is inclinedly screwed. SOLUTION: The outside diameter of an annular salient 3 formed at the tip of a bolt shaft 1 is made slightly smaller than the inside diameter of a female thread 4 which pairs with the outside diameter of the salient, the shape of the cross section of the outside diameter is made capable of engaging with a screw groove of the female thread 4, and a non-threaded portion 6 is formed between the annular salient 3 and a male thread 2.

摘要： PROBLEM TO BE SOLVED: To provide a bolt capable of guiding itself inside a screw hole of a female screw component with a compact guide portion and screwing the bolt into the female screw component without galling. SOLUTION: The bolt 1 has a reduction diameter portion 12 at a tip of a shaft portion, and the minimum value d1 for a thread-top diameter of an imperfect thread portion 20b formed on the reduction diameter portion 12 is larger than the root-bottom diameter of an imperfect screw portion 20a of an uniform diameter portion 11. A thread-top diameter of the uniform diameter portion 11 at the bolt 1 is smaller than a root diameter of a nut 70, and the bolt 1 is engaged with a screw hole 71 of the nut 70. The minimum value d1 for the thread-top diameter of the reduction diameter portion 12 can be set to be approximately the same as an inner diameter d3 of the nut 70. Therefore, both the bolt 1 and the nut 70 can be engaged with each other without generating a gap between a guide portion 15 of the bolt 1 and the screw hole 71 of the nut 70, and the bolt 1 is surely prevented from galling with the nut 70.

摘要： PROBLEM TO BE SOLVED: To provide a bolt which can surely prevent the scoring and seizure with a female screw member by interrupting the screwing when an appropriate screwing posture with respect to the female screw member is not yet achieved. SOLUTION: The bolt 1 has a small diameter guide portion 116 formed at the tip end of its body portion 15. The guide portion 116 has an screw thread 31 having the hand of helix opposite to that of the screw thread 30 formed on a constant diameter portion 115. By this configuration, if the posture of the bolt 1 does not become appropriate by its own weight when the bolt 1 has been inserted into a nut 100, the bolt 1 cannot be screwed into the nut 100 so far as the posture of the bolt 1 is not changed to be suitable for the nut 100. Therefore, it is impossible that the bolt 1 is fitted in the nut 100 in the unsuitable state, such as a tilting state, etc. As a result, the scoring and seizure of the bolt 1 with the nut 100 can be surely prevented.

摘要翻译：要解决的问题：提供一种螺栓，当不能获得相对于内螺纹部件的适当的拧紧姿态时，可以通过中断旋拧来确保地防止用内螺纹部件进行打分和卡住。解决方案：螺栓1具有形成在其主体部分15的尖端处的小直径引导部分116.引导部分116具有螺纹31，螺纹线31具有与形成在螺纹30上的螺纹30相反的螺旋针恒定直径部分115.通过这种构造，当螺栓1已经插入螺母100中时，如果螺栓1的姿态由于其自身重量而不适合，则螺栓1不能拧入螺母100中，只要螺栓1的姿势没有改变为适合于螺母100.因此，螺栓1不可能在诸如倾斜状态等不适当状态下装配在螺母100中。结果，可以可靠地防止螺栓1与螺母100的打击和卡住。版权所有（C）2005，JPO＆NCIPI
