PROBLEM TO BE SOLVED: To provide a power transmission device which transmits power between a first member and a second member and expands an angle formed between an axis line of the first member and an axis line of the second member.SOLUTION: A power transmission device of the invention includes: a first member 1 which may rotate around an axis line 1a; a second member 2 which is rotatably connected with the first member 1 through a first joint 3; and multiple rods 4 which are rotationally connected with a periphery of the first joint 3 of the second member 2 through multiple second joints 8 and connected with the first member 1 so as to move in a length direction. Torque of the first member 1 is transmitted to the second member 2 through the multiple rods 4. |
