<p>PROBLEM TO BE SOLVED: To provide a rotation acceleration device capable of reducing energy used for a rotation of a member to be rotated.SOLUTION: This invention relates to a rotation acceleration device comprising: discs 24 and 26 having axial lines extending in a horizontal direction arranged in parallel at the same height and rotatably supported around the axial lines and having a first or second through-hole formed at the same phase positions on the same radius; a plate-like rotary body 21 disposed between the discs 24 and 26 on a line connecting the axial lines of the discs 24 and 26 perpendicular to each other and having a plurality of supporting holes 21a at the same height as that of the through-hole; a plurality of supporting members 35 rotatably arranged at the supporting holes and having a third or fourth through-hole formed on the same axial lines as that of the first or second through-hole; a plurality of connecting pins 33 having one end side fixed to the first through-hole and the other end side rotatably inserted into the third through-hole formed at the supporting members 35; a plurality of connecting pins 34 having one end side fixed to the second through-hole and the other end side rotatably inserted into the fourth through-hole formed at another supporting member 35; and a tension spring 27 for biasing the rotary body 21 in a vertical direction.</p> |
