To provide a filament fixation mechanism capable of sufficiently fixing a filament without being welded to the filament.
This filament fixation mechanism is provided with: first and second members 20 and 30 arranged oppositely to each other by interposing an end 4AT of the filament; a holding plate 40 sandwiched between the first and second members 20 and 30 along with the end 4AT of the filament; and a bolt 50 fastening the second member 30 to the first member 20. The first member 20 has arm parts 22 and 23 projected from a column part 21 in a direction intersecting with the fastening direction of the bolt 50. The second member 30 has hook parts 32 and 33 erected at both ends of a flat plate part 31. By rotating the bolt 50 in the fastening direction, the arm parts 22 and 23 come into contact with the hook parts 32 and 33, and thereafter the end 4AT of the filament is sufficiently firmly held by the holding plate 40 and a contact region 21S of the column part 21.
