PROBLEM TO BE SOLVED: To provide a placing machine having high durability and high pressure.SOLUTION: A lower end of a bumper 20 is supported by a taper face 14B. Therefore, before and after compressive deformation (figure 3(a)(b)), a lower face of the bumper 20 and the taper face 14B contact by surface contact. The taper face 14B is inclined from a horizontal plane so as to become higher at outside when viewed from a driver blade 13, and an upper face of a nose 14 is a conical shape (taper shape). The taper angle (angle formed of the horizontal plane and taper face 14B) is &thetas; in the figure 3. The lower face of the bumper 20 is supported by only the taper face 14B formed into the taper shape. Therefore, a maximum distortion amount in the bumper 20 can be reduced, and durability of the bumper 20 and a placing machine 100 can be enhanced. |
