Definitions

  • the guide bar body 1 has a reinforcement portion including two beam portions f1 and f2 in one filling hole 2a.
  • Each of the beam portions f1 and f2 extends linearly so as to connect two parts of a side wall (inner wall) of the filling hole 2a.
  • the two beam portions f1 and f2 are tilted in opposite directions with respect to the central axis line CL of the guide bar body 1 and intersect each other (intersection fx).
  • the guide bar body 1 has a projecting portion t1 extending inward from a central portion in the thickness direction of the side wall (inner wall) of the filling hole 2a.
  • the beam portions (f1 to f4, f7, f8, and f11 to f16) forming the reinforcement portion are tilted with respect to the central axis line CL of the guide bar body 1, unlike the beam portion such as the beam portion f51 of Fig. 5 having a center line parallel to or coinciding with the central axis line CL of the guide bar body 51, or the beam portion such as the beam portion f52 of Fig. 5 having a center line intersecting with the central axis line CL.
  • the beam portions f1 to f4, f7, f8, and f11 to f16
