| description | To provide a camshaft structure which can improve friction, can reduce the number of components, and can improve a degree of freedom in peripheral design.SOLUTION: A camshaft structure 10 includes a shaft body 16, a first journal 28 formed in a part of the shaft body 16 and supported by a first bearing 32, a second journal 30 provided adjacently to the first journal 28 and supported by a second bearing 34, and a plurality of cams 18 arranged in an axial direction of the shaft body 16 so as to open and close a valve provided for each of cylinders. Among the plurality of cams 18, all of first cams 18A (cams 18a, 18b) corresponding to a first cylinder S1 (first cylinder) and a part of second cams 18B (cam 18c) corresponding to a second cylinder S2 (second cylinder) adjacent to the first cylinder S1 are located between the first journal 28 and the second journal 30.SELECTED DRAWING: Figure 2
【課題】フリクションの改善、部品点数の削減、周辺の設計自由度の向上が可能なカムシャフト構造を提供する。【解決手段】カムシャフト構造１０は、シャフト本体１６と、シャフト本体１６の一部に形成され、第一の軸受部３２に支持される第一のジャーナル部２８と、第一のジャーナル部２８に隣接して設けられ、第二の軸受部３４に支持される第二のジャーナル部３０と、シャフト本体１６の軸方向に配列されて、気筒ごとに設けられたバルブの開閉を行う複数のカム部１８と、を備える。第一のジャーナル部２８と第二のジャーナル部３０との間には、複数のカム部１８のうち第１気筒Ｓ１（第１の気筒）に対応する第一のカム部１８Ａの全て（カム部１８ａ，１８ｂ）と、第１気筒Ｓ１に隣接する第２気筒Ｓ２（第二の気筒）に対応する第二のカム部１８Ｂの一部(カム部１８ｃ)が位置されている。【選択図】図２ |
