摘要： A lift-variable valve-operating system for an internal combustion engine, comprising: subsidiary cams which are swingably supported on a movable support shaft capable of being displaced within a plane perpendicular to a rotational axis of a valve-operating cam, and which are swung following the valve-operating cam; and rocker arms each operatively connected to an engine valve and operated following the subsidiary cams, operating characteristics including a lift amount of the engine valve being changed by displacing the movable support shaft, wherein the system further includes a control arm carried in an engine body to be capable of turning about a turning axis parallel to a rotational axis of the valve-operating cam, wherein the movable support shaft having an axis parallel to the turning axis of the control arm is retained on the control arm at a location offset from the turning axis, wherein a hydraulic tappet is mounted in the control arm to support one end of each of the rocker arms, and wherein a valve abutment portion provided at the other end of each of the rocker arms is in abutment against an upper end of a stem of the engine valve. Thus, it is possible to enhance the control accuracy in a state in which the lift amount of the engine valve is controlled to be low.

摘要： In a lift amount adjusting device in a valve-operating mechanism which changes at least a lift amount, a rocker arm is rockably arranged in a driving-force transmitting path for transmitting a driving force of a valve cam to an engine valve, and a jig abuts on the rocker arm to establish a rocking fulcrum in place of a hydraulic tappet which generates an urging force for adjusting a clearance of the driving-force transmission path. Even when an engine is stopped to make the hydraulic tappet inoperative, the jig secures a rocking fulcrum of the rocker arm, thereby enabling adjustment of the lift amount of the intake valve. Also, a load acting on the rocker arm during the adjustment of a lift amount of the intake valve is supported by the jig, and is not transmitted to the hydraulic tappet.

摘要： The present invention provides an electromagnetic relay that can achieve desired operation characteristics by simple and inexpensive construction even if it has a small thickness. Therefore, a movable iron piece 20 is rotated by excitation or non-excitation of an electromagnet, a movable contact piece 43 is elastically deformed through a card 21, and a movable contact 46 opens and closes fixed contacts of fixed contact pieces. The movable iron piece 20 is provided with a card pressing portion 36 capable of pressing the card 21. The card 21 is provided with a contact piece pressing portion 37 capable of pressing the movable contact piece 43 by being rotated around a fulcrum. At least one of the movable iron piece and the card is provided with a press position changing portion, wherein when rotating the movable iron piece 20, force transmission from the movable iron piece 20 to the card 21 is performed at a position more distant from a press position by the card pressing portion 36 of the iron piece 20 with respect to the fulcrum, and then performed by the card pressing portion 36.
