る。For example, a spring or the like is used for the pressure mechanism 12, and the pressure mechanism 1
2 so that the adjustment screw 2 is pressed against the tappet 1 side.
検出器１３には例えば電子マイクロメータなどを使用し
、検出器１３を接触子１１に接触させておくことにより
調整ネジ２の移動距離を間接的に測定する。For example, an electronic micrometer is used as the detector 13, and by keeping the detector 13 in contact with the contact 11, the moving distance of the adjustment screw 2 is indirectly measured.
カム５と反対側の端部３２に接触させる駆動機構１４に
は例えばエアシリンダなどを使用し、駆ｗＪ機構１４に
より端部３２をカム５側に押し付けるようにする。For example, an air cylinder or the like is used as the drive mechanism 14 that brings the end 32 into contact with the end 32 on the opposite side to the cam 5, and the drive wJ mechanism 14 presses the end 32 toward the cam 5.
なお、駆動機構１４は、端部３２がカム５の頁内部５１
に接している状態のときに動作させるようにする。頁内
部５１はカム５の半径が最も短い部分であり、端部３２
が頁内部５１に接しているときは、調整ネジ２がタペッ
ト１から最も遠ざかった状態になっている。Note that the drive mechanism 14 has an end portion 32 that is located inside the page 51 of the cam 5.
Make it work when the object is in contact with the object. The inside page 51 is the part where the radius of the cam 5 is the shortest, and the end part 32
When is in contact with the inside of the page 51, the adjustment screw 2 is in the farthest position from the tappet 1.
次に、第１図の測定装置によりクリアランスＣを測定す
る方法を説明する。Next, a method of measuring the clearance C using the measuring device shown in FIG. 1 will be explained.
最初に、端部３２をカム５０基内部５１に接触させる。First, the end 32 is brought into contact with the interior 51 of the cam 50.
第２に、加圧機構１２により調整ネジ２をタペット１側
に押し付け、調整ネジ２がタペット１に接触するように
する。このときの検出器１３の指示値をＡとする。Second, the adjustment screw 2 is pressed against the tappet 1 side by the pressure mechanism 12 so that the adjustment screw 2 comes into contact with the tappet 1. Let A be the indicated value of the detector 13 at this time.
第３に、駆動機構１４を動作させ、端部３２を／Ｊム５
側に押し付ける。この状態では、調整ネジ２がクリアラ
ンスＣだけタペット１から離れることになる。このとき
の検出器１３の指示値をＢとする。Third, operate the drive mechanism 14 to move the end portion 32 to the
Press it to the side. In this state, the adjustment screw 2 is separated from the tappet 1 by a clearance C. The indicated value of the detector 13 at this time is assumed to be B.
第４に、（Ａ−Ｂ）を計算し、この計算結果をクリアラ
ンスＣとする。Fourth, calculate (A-B), and use this calculation result as clearance C.
すなわち、この発明はロッカーアーム３の遊びの量を測
定し、この測定値をクリアランスＣとするものである。That is, the present invention measures the amount of play in the rocker arm 3 and uses this measured value as the clearance C.
