Zusammenfassung:PROBLEM TO BE SOLVED: To improve the assembling workability of a rocker arm.SOLUTION: At one end portion in a length direction of an arm body 12, a valve receiving portion 13 which has an abutting wall 17 and a pair of opposing walls 16 projecting out from both end portions of the abutting portion 17 and opposing to each other is provided. A surface side opposing to the abutting wall 17 of the valve receiving portion 13 is opened as a penetration port 25. The valve receiving portion 13 has an extraction regulating portion 27 formed on the opposite wall 16, and abutting on a head portion 83 of a valve stem 80 to regulate the extraction of the head portion 83 from the penetration port 25; an introduction port 26 crossing and communicating with the penetration port 25 to open at the one end in the length direction of the arm body 12, and introducing the head portion 83 into the valve receiving portion 13; and an advance regulating portion 24 formed at a position opposite to the head portion 83 in an advancing direction, and abutting on the head portion 83 to regulate the further advancing of the head portion 83.SELECTED DRAWING: Figure 1 【課題】ロッカアームの組み付け作業性を改善する。【解決手段】アーム本体12の長さ方向の一端部には、当接壁17とこの当接壁17の両端部から突出して互いに対向する一対の対向壁16とを有するバルブ受け部13が設けられている。バルブ受け部13の当接壁17と対向する面側は貫通口25として開放されている。バルブ受け部13は、対向壁16に形成され、バルブステム80の頭部83に当接することで頭部83が貫通口25から抜け出るのを規制する抜出規制部27と、貫通口25に交差連通してアーム本体12の長さ方向の一端に開口し、バルブ受け部13内に頭部83を導入する導入口26と、頭部83の進行方向と対向する位置に形成され、頭部83と当接することで頭部83のそれ以上の進行を規制する進行規制部24とを有している。【選択図】図1
