PURPOSE: An abrasion prevention unit is provide to increase life of glasses, to improve elasticity of temple and efficiency of function by structuring elasticity unit for assembling abrasion prevention unit and compression-spring. CONSTITUTION: A front section of temple(2) has a hole(6) with depth of specified size to be able to insert and fix an elasticity unit(5). A connection part(7) connected the elasticity unit(5) with glasses frame welded and fixed to both of backside section. The elasticity unit(5) inserted and fixed into hole(6) of temple(2) connected with the connection part(7). The elasticity unit(5) is composed of connection head(52) with hinge hole(51) at front section, a body with spring insertion bar(53), the abrasion prevention unit(55) inserted in the body, and compression-spring(56). The abrasion prevention unit(55) is made of stainless or Ni. A fixed tube unit has a rub unit and principle unit. A connection unit(7) connect the rub unit with the fixed unit. The rub unit and the connection unit(7) is formed both side of fixed tube unit parallel.
