Description
【発明の詳細な説明】 （技術分野） 本、発明は丸軸の抜は防止方法に関するものである。[Detailed description of the invention] (Technical field) The present invention relates to a method for preventing removal of a round shaft.

う欠点があった。(Prior art) Conventionally, in order to fit a round shaft into a predetermined member and prevent the round shaft from coming off, an annular groove is formed on the outer periphery of the round shaft at a predetermined position, and an E-ring is fitted into the annular groove. The commonly used solution is that the annular groove must be cut using a lathe, so it is only a matter of manual labor, and methods using split pins and spring pins are also widely used, but for round shafts. This method has the disadvantage that processing is troublesome because it is necessary to form a cotter pin and a spring pin insertion hole.

である。(Structure) The structure of the present invention will be explained below based on one embodiment.
A guide hole 1α is formed at the end of the guide hole 1α. 2 is a T-shaped fastening member, and a straight part 2a is inserted into the guide hole la.
An engaging portion 2'C having an arcuate inner surface 2b that comes into contact with the outer shell of the round bar 1 is formed. When the straight part 2α of this fastening member 2 is inserted into the guide hole la of the round bar l, the retaining part 2C is deformed and restored by its own elasticity, and its arcuate inner surface 2b is brought into contact with the outer surface of the round bar 1 and fastened. The member 2 is locked to the round bar 1.

した丸軸の抜は防止方法。A guide hole □ is formed in a direction perpendicular to a predetermined position of the round shaft, and the straight part of a T-shaped fastening member consisting of a straight part that can be inserted into the guide and a retaining part that comes into contact with the outer surface of the round shaft is inserted into the guide hole. At the same time, the engaging part is deformed and restored by its own elasticity and comes into contact with the outer surface of the round shaft, thereby locking the fastening member to the round shaft.
