摘要:
A bolt fastening method enabling the same effect as when reducing the coefficient of friction of a thread surface without changing the coefficient of friction of the thread surface so as to realize an increase in a bolt axial force generated when fastening the bolt and a bolt fastening device realizing the bolt fastening method are provided.The bolt fastening method of the present invention is a bolt fastening method for when using a bolt having a bolt head and a bolt shank provided with an external thread to fasten fastened members, characterized by intentionally biasing surface pressures of a thread surface and a bolt bearing surface generated when fastening the bolt by imparting a lateral load parallel to the bolt bearing surface to the bolt head and, in that state, imparting a rotational torque rotating the external thread to the bolt head so as to fasten the bolt.

While a video information providing host is sending video information to a user terminal through a transmission line corresponding to a request received from the user terminal, an operation history information writing unit writes an operation history for various operations for video information of the user terminal as operation history information to an operation history storing unit. The operation history information is written for each of a plurality of types of video information and for each of users who use user terminals that access each of the types of video information or each of user terminals that access each of the types of video information. While a video information editing unit is editing requested video information corresponding to a request received from a user and corresponding to operation history information, the video information editing unit sends the edited video information to a user terminal that the requesting user operates.
