摘要： A rocker arm 1 includes an arm body 4 prepared from a single plate material by means of a press work. The arm body 4 includes a pair of parallel side walls 5 and a connecting wall 6 bridging between the opposite side walls 5 and also having a pivot support hole 7 defined at a location generally intermediate of the length of the arm body 4. A roller support pin for rotatably supporting a roller 10 for driving engagement with a cam is mounted on one ends 1a of the opposite side walls 5, while the opposite end 1b of the connecting wall 6 defines an overlapped structure 13 formed by bending an end overlap piece 12, extending integrally from a side edge of the connecting wall 6, backwardly to overlap the connecting wall 6. This overlapped structure 13 in turn defines an adjustment element 16 having a mounting hole 15 defined therein for adjustably receiving a valve driving member 14. The rocker arm 1 may be designed to be an end pivot type, in which case the adjustment element 16 is provided with a pivot member.

摘要： To provide a rocker arm of a design effective to avoid occurrence of a loosening of the adjustment screw to ensure a proper operation of the internal combustion engine including the control of the opening of the valve body on the engine cylinder head, the rocker arm 1 is of a type capable of being rockingly driven by a cam 2 for selectively opening and closing a valve of an internal combustion engine. The rocker arm 1 includes an arm body 4 prepared from a steel plate by means of a press work to have a generally inverted U-shaped section. The arm body 4 has one end formed with an internally threaded hole 12 into which an adjustment screw 7 is threaded. This adjustment screw has one end defining a pivot piece 7b or a valve drive piece 7Ab. Two nuts 13 and 14 are threadingly mounted in overlapping relation to each other on one end portion of the adjustment screw 7 protruding outwardly from the arm body. Instead of the use of the two nuts 13 and 14, a flanged nut may be employed or a single nut 13 in combination with a washer 17 may be employed.

摘要： There is provided a rocker arm of a kind in which even though the rocker arm is manufactured by the use of a press working technique the arm width can be minimized while the flat outer surface region of a required width is secured on an outer surface of the connecting wall, thereby contributing to reduction in size and weight of the rocker arm. This rocker arm is capable of being driven by a cam for selectively opening and closing a valve of an internal combustion engine. This rocker arm includes an arm body prepared by bending a single plate material to represent a generally inverted U-shaped section including opposite side walls and a connecting wall bridging between the opposite side walls. A roller engageable with the cam is rotatably mounted on a portion of the arm body generally intermediate of the length thereof. A valve drive element is mounted on one end of the arm body for driving the valve, while an end portion of the connecting wall adjacent the other end of the arm body is formed with an internally helically threaded hole for threadingly receiving therein an externally helically threaded pivot member. An outer chamfered corner delimited between an outer surface of the connecting wall and an outer surface of each of the opposite side walls and formed by bending is deformed to represent a plastically deformed portion so formed by means of a plastic deformation technique that the outer chamfered corner represents a small radius of curvature R.
