    Abstract: Eine Aufgabe besteht in der Bereitstellung eines Rollenhebers, der eine passende Abmessungsgenauigkeit eines Außendurchmessers erhalten kann. Eine Welle (25), die eine Rolle (30) drehbar stützt, ist durch ein Paar von entgegengesetzten bzw. gegenüberliegenden Abschnitten (21) eingeführt und wird zur Fixierung gestaucht. Ein zylindrischer Abschnitt (61) ist zur Fixierung an einer Relativposition hinsichtlich der entgegengesetzten bzw. gegenüberliegenden Abschnitte (21) angeordnet. Bei Drehung einer Nocke (90) wird der zylindrische Abschnitt (61) über die Rolle (30) hin und herbewegt. Der Rollenheber (10) beinhaltet ein erstes Element (20), in dem die Welle (25) zur Fixierung an den entgegengesetzten bzw. gegenüberliegenden Abschnitten (21) gestaucht wird, und ein zweites Element (60), das von dem ersten Element (20) getrennt und über ein Kopplungselement mit dem ersten Element (20) koppelbar ist. Das zweite Element (60) beinhaltet wenigstens den zylindrischen Abschnitt (61).

    Abstract: A lash adjuster includes a cylindrical bottomed plunger (12) mounted in a cylindrical bottomed body (11) so as to be movable upward and downward and including a high-pressure chamber (25) defined between an underside of the plunger (12) and a bottom wall of the body (11) to reserve an operating oil, a leak path (32) defined by an inner circumference of the body (11) and an outer circumference of the plunger (12) so that the oil reserved in the high-pressure chamber (25) leaks through the leak path (32) with downward movement of the plunger (12), and a ring-shaped member (34) located between the inner circumference of the body (11) and the outer circumference of the plunger (12), normally projecting into the leak path (32) and being elastically deformed radially inward or outward with increase in pressure of the oil at the high-pressure chamber (25) side so as to be retreated from the leak path (32), thereby reducing flow resistance of the oil in the leak path (32).

    Abstract: Promotion of a productivity is achieved by facilitating a gap control. A lash adjuster 10 of the invention includes a body 20 in a cylindrical shape and a plunger 60 inserted to inside of the body 20. The plunger 60 partitions a high pressure chamber 26 at inside of the body 20 by being integrated to the body 20, and is moved in an axial direction at inside of the body 20 by increasing or reducing a volume of inside of the high pressure chamber 26 by making a working fluid flow to inside of the high pressure chamber 26 or flow out from the high pressure chamber 26. Further, between an inner peripheral face of the body 20 and an outer peripheral face of the plunger 60, a spacer 50 filling a gap between the two faces is interposed.

    Abstract: PROBLEM TO BE SOLVED: To provide a roller lifter for an internal combustion engine allowing miniaturization with hardly generating cock in relation to a cylinder with high rigidity of a lifter body.SOLUTION: A roller lifter 1 includes a cylindrical lifter body 2 with a sliding surface 24 on an outer peripheral surface thereof, and a roller 3 which is rotatably mounted in the lifter body 2 via a journal pin 4 and abuts on a rotating cam 6. The lifter body 2 includes a pair of support sections 21 for supporting the journal pin 4. The journal pin 4 has both ends 40 fitted in support holes 22 provided in the pair of support sections 21 and is fixed to the support sections 21 by caulking. The lifter body 2 includes a detent section 23 projecting to the radial direction outside from the sliding surface 24. In both of a front side and a rear side of the detent section 23 in the sliding direction, the sliding surface 24 is formed.
