Slider and slider assembling method

A slider for a slide fastener in which the slider is attached to fastener chains, the slider comprising:

• a first member that includes an upper blade, a lower blade, a guide post connected between the upper blade and the lower blade, and a connecting post protruding from the upper blade;
• and
• a second member that includes a first arm and a second arm separated from each other, is attached to the first member by the first arm and the second arm, and is configured to rotate along an upper-lower direction relative to the first member and around a fulcrum defined by the upper blade or the lower blade,
• wherein:
• the first member or the second member defines a flange;
• three or more fit sections are formed between the first member and the second member;
• the first arm defines a first fitting portion and the second arm defines a second fitting portion;
• the first member defines a first counter-fitting portion and a second counter-fitting portion respectively corresponding to the fulcrum at left and right sides of the first member;
• the first fitting portion and the second fitting portion are fitted to the first counter-fitting portion and the second counter-fitting portion such that the first arm and the second arm of the second member are coupled to the left and right sides of the first member, to form a first fit section and a second fit section among the three or more fit sections;
• a third fitting portion is defined in an end portion of the second member opposite to the fulcrum in a length direction of the slider, and a third counter-fitting portion is defined in an end portion of the first member opposite to the fulcrum in the length direction, and
• the third fitting portion is fitted to the third counter-fitting portion such that the end portion of the second member is coupled to the end portion of the first member, to form a third fit section among the three or more fit sections.
