<P>PROBLEM TO BE SOLVED: To provide an axial coupling device and a torque limiter with a long service life and high reliability preventing easy fracture of welding parts in both sides of a fluid pressure passage. <P>SOLUTION: In one side in an axial direction of a fluid pressure expansion chamber 26, a first part 70 and a second part 71 are joined by a first welding part 60, and in another side in the axial direction of the fluid pressure expansion chamber 26, the first part 70 and the second part 71 are joined by a second welding part 61. In the first welding part 60, a joining face 80 positioned between the first part 70 and the second part 71 in a radial direction is positioned radially outward than the fluid pressure expansion chamber 26 in the radial direction, and in the second welding part 61, a joining face 81 positioned between the first part 70 and the second part 71 in the radial direction is positioned radially inward than the fluid pressure chamber 26 in the radial direction. <P>COPYRIGHT: (C)2010,JPO&INPIT |
