    摘要： A compressor housing 1 for a turbocharger, which is composed of a scroll piece 20, a shroud piece 30, and an outer-circumferential annular piece 40. The scroll piece 20 includes a through part 22 constituting a discharge port 13, a first intermediate wall surface 23 extended from an intake-side wall surface 21 of a scroll chamber 12 and smoothly connected with the discharge port 13, and a scroll outer-circumferential part 24. The outer-circumferential annular piece 40 includes an outer-circumferential annular press-fit part 44 press fitted into the scroll outer-circumferential part 24, and a protruding part 42 bent from an outer-circumference-side wall surface 41 of the scroll chamber 12. The protruding part 42 is inserted into the through part 22 to form an inner wall surface 14a of an intermediate part 14 that communicates the discharge port 13 with the scroll chamber 12. Then, the compressor housing 1 is fixed to a center housing 2 that is made of iron with high rigidity through joining parts 25 provided at the scroll piece 20.

    摘要： A lash adjuster includes a body (11) which is cylindrical in shape and a plunger (12) reciprocably inserted into the body (11) and having an interior in which a low-pressure chamber (24) is defined. The plunger (12) has a bottom wall (18) defining a high-pressure chamber (28) in conjunction with the body (11) between them and a peripheral wall (19) formed with a plunger oil hole (26) through which an operating oil is fed into the low-pressure chamber (24). The bottom wall (18) is formed with a valve hole (23) through which the operating oil stored in the low-pressure chamber (24) is allowed to flow into the high-pressure chamber (28). The peripheral wall (19) is formed with a pocket (27) deformed toward the low-pressure chamber (24) and inclined in an upward direction, defining the plunger oil hole (26).

    摘要： The present invention provides a variable valve mechanism of an internal combustion engine which includes a rotary cam (10), an output arm (20), an input member (30), and a switching device (40) that switches between a coupled state and a non-coupled state. The variable valve mechanism changes a drive state of the valve by the switching operation. The input member (30) includes an annular input roller (38) that contacts the rotary cam (10), and a swing pin (31) that is inserted into the input roller (38) so as to rotatably support the input roller (38) and that swings relative to the output arm (20) when in the non-coupled state. A center (B) of the relative swinging movement is located at a position different from a rotation center (A) of the input roller (38) which is located inward of the input roller (38).

    摘要： A bearing structure (1) of a turbocharger includes a rotor shaft (10), two angular ball bearings (20), a retainer (60), a housing (30), and an oil film damper (50). Each of the angular ball bearings (20) includes an inner ring (21) and an outer ring (22) that are supported in relatively rotatable manner. The rotor shaft (10) is inserted into the inner ring (21). The retainer (60) holds the outer ring (22). The housing (30) houses therein the rotor shaft (10), the angular ball bearings (20), and the retainer (60) to constitute a bearing housing. The oil film damper (50) is formed of oil in a film state and is interposed between the inner ring (21) and an outer peripheral surface (10c) of the rotor shaft (10). The inner ring (21) is configured to rotate with rotation of the rotor shaft (10) via the oil film damper (50).

    摘要： A lifter includes a roller (30) caused to abut against a cam (70) and housed in a guide hole (83) of a lifter guide (82). The lifter body (11) includes a cylindrical part (12) and a rotation stopper (21). The cylindrical part (12) has an outer periphery formed into a cylindrical shape such that the outer periphery is slidable on an inner periphery of the guide hole (83). The cylindrical part (12) has one of two axial ends, the one end being formed with a skirt (13) covering the roller (30). The rotation stopper (21) is formed to protrude outward from the other axial end of the cylindrical part (12), the other axial end being located opposite a side where the skirt (13) is located. The rotation stopper (21) prevents the lifterbody (11) from being rotated about an axis thereof relative to the lifter guide (82).
