    摘要: A component of a crank mechanism is incorporated in the crank mechanism that converts reciprocating motion of a piston to rotary motion by means of a crank pin, a crank arm and a crank shaft via a connecting bar, and has a hydrogen content of no more than 0.5 ppm, austenite crystal grains of a grain size number exceeding 10, or a fracture stress value of no less than 2650 MPa. Thus, a support structure in and a component of a crank mechanism ensuring a long fatigue life, high anti-crack strength, and a reduced rate of secular dimensional change to improve dimensional stability, can be obtained.

    摘要: A cam follower with roller of the present invention includes a cam follower body having a roller supporting portion integrated therein, a roller supporting shaft having both ends fixed to the roller supporting portion and a roller rotatably supported on the roller supporting shaft with a plurality of needle rollers interposed. At least one of the supporting shaft and the needle roller has a nitride layer on the surface thereof, and has a surface hardness of at least HV 650 and an amount of retained austenite of at least 25% by volume and at most 50% by volume. Thus, a cam follower with roller having excellent durability and fatigue life can be obtained.
