Document Type and Number:
Japanese Patent JP2017089717
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a fastening tool capable of restricting a fastened state of an item to be fastened from being released in useless manner.SOLUTION: An oscillating operation of a lever 51 performed by fingers of a user is prohibited by a lower recess part 43 arranged at a fastening part 4. A reason for it consists in the fact that since an inner side surface lever of the lower recess part 43 is arranged near the extremity end part of the lever 51, it is difficult for a user to apply fingers against the lever 51. A user inserts a screw driver B into a part 515 to be inserted arranged at the lever 51 to perform an oscillation work for the lever 51. That is, it is necessary to apply the screw driver B in order to perform an oscillation work for the lever 51 and it is difficult for a user to perform an oscillation work for the lever 51 with user's fingers. Accordingly, a useless releasing of an engagement of the fastening part 4 to a fastening part 3 by an engaging structure 5 is restricted, so that a problem in which a useless releasing of the fastened state of an item A to be fastened is eliminated.SELECTED DRAWING: Figure 1
