PURPOSE: To ensure a firm connection between a tie rod and a sleeve by forming an inclined outer surface at an interval from an open end of a sleeve axially at the sleeve, and forming an inclined inner surface brought into face contact with an inward spaced surface capable of accodating a screw and the open end and the inclined outer surface at a nut. CONSTITUTION: A sleeve 20 is provided with ends 22, 24 engaging with portions 66, 68 of a tie rod 14. The ends 22, 24 are respectively provided with clamp parts 36 having an open end 32, annular end face 34, cylindrical outer face 38 and truncated cone outer face 40. The end 22 has an inner surface 42 with a rightward thread sandwittching a non-thread region while the end 24 has the same structure as the end 22 except that it has a leftward thread. A nut 50 has an open end 52 accomodating the end 22 concentrically, an inner face 54 corresponding to the annular end face 34, an inclined inner face 56 being in surface contact with the outer face 40, an inner face 62 with a rightward thread. A nut 59 has an inner face with a leftward thread. Accordingly, the purpose is attained. |
