Japanese Patent JP5424446
Kind Code:
B2
Abstract:
To increase the pressing force on a chain as the chain undergoes greater elongation. [Resolving Means] Provision is made for: a tensioner arm 2 in which a through-hole 21a is formed at a free end 21 which can pivot about a pivoting end 20; a hydraulic tensioner 3 for causing the tensioner arm 2 to pivot about the pivoting end 20; a lever arm 4 having a boss part 40 which is rotatably supported in the through-hole 21a at the free end 21 and comprises a pin insertion hole 40a at a position which is offset from the center O of the through-hole 21a, said lever arm also having a lever part 41 which extends from the boss part 40 toward the hydraulic tensioner 3 with the tip end of a piston 3a of the hydraulic tensioner 3 in abutment against it; and a pin 5 of which one end is fitted in a fixed wall 50, and of which the other end is inserted into the pin insertion hole 40a of the boss part 40 of the lever arm 4. When the piston 3a of the hydraulic tensioner 3 extends, the lever arm 4 pivots about the pin 5, whereby the amount of pushing by the free end 21 of the tensioner arm 2 into a chain 104 is increased.
