ことを特徴とするチエーンテンシヨナ装置。 In a chain tensioner device that is equipped with a chain guide that presses and guides the chain in a chain drive device and a pushing device that pushes the chain guide, the pushing device slides between a pushing rod that comes into contact with the chain guide and a pushing rod. The first part that can be attached freely
a first body in which a concave hole is formed; a first spring installed in the first concave hole to elastically bias the pushing rod in a direction in which the pushing rod protrudes from the first concave hole; a second lock mechanism that allows the first body to move in the same direction as the protruding direction and prevents the first body from moving in the opposite direction to the protruding direction; a second body in which a concave hole is formed;
mounted in the second concave hole so as to elastically bias the body in the direction of protruding from the second concave hole;
A chain tensioner device comprising: a second spring having a spring constant larger than that of the spring; and a forward stop mechanism that limits movement of the first body in the projecting direction.
