Abstract

PURPOSE:To reduce the manufacturing cost by forming an eye part of an outer cylinder member formed of a first cylinder part and a first bottom part having a first center hole, and an inner cylinder member formed of a second cylinder part and a second bottom part having a second center hole, and press-fitting the second cylinder part into the first cylinder part so as to connect the inner cylinder member integrally to the outer cylinder member. CONSTITUTION:An eye part 1 is formed of an outer cylinder member 10 and an inner cylinder member 11. The outer cylinder member 10 is of bottomed cylindrical shape, and formed of a first bottom part 10b provided with a first center hole 10a, and a first cylinder part 10c protruding from the peripheral edge part of the first bottom part 10b. The inner cylinder member 11 is also of the same bottomed cylindrical shape, and formed of a second bottom part 11b provided with a second center hole 11a, and a second cylinder part 11c protruding from the peripheral edge part of the second bottom part 11b. The diameters of the first and second center holes 10a, 11a are to be the same, but the outer diameter of the second cylinder part 11c is slightly larger than the inner diameter of the first cylinder part 10c. This eye part 1 is integrally connected by press-fitting the second cylinder part 11c into the first cylinder part 10c from the opening side.
