PURPOSE:To suppress generation of vibration and to reduce mounting time for components by moving a weight with the same mass as the traveling part of a fitting head in the opposite direction as the fitting head and at the same speed. CONSTITUTION:The mass of a first weight 6 is equal to that of a fitting head 1, the total mass of second and third weights 8 and 10 is equal to the mass of a part which is driven by second and third drive shafts 3 and 4, and the resultant gravity center position is equal to the partial gravity center position of a part which is driven by the second and third drive shafts 3 and 4 in the direction of a first drive shaft 2. Also, the first weight 6 has an equal speed as the fitting head 1 in opposite direction and the second and third weights 8 and 10 are driven at the same speed in the opposite direction to the traveling direction of the mass which is driven by the second and third drive shafts 3 and 4, thus canceling the inertial force of the fitting head 1 with those of weights 6, 8, and 10 and reducing the mounting time per component without generating vibration of the body. |
