CONSTITUTION: A tight fixing device(F) comprises a body(10), a rotating body(20), and a plurality of tension members(30). The body comprises a plurality of fixing parts(13) and a spiral part(11). The spiral part(21) of the rotating body is coupled to the spiral part of the body. The rotating part presses an object to be fixed. One end of the tension member is coupled to the fixing part of the body. The other end of the tension member is coupled to the fixing member.
