    摘要: A camshaft device (10) includes a camshaft (11) onto which a cam (18) is fitted; a plurality of rolling bearings (12) that are fitted at intervals in an axial direction onto this camshaft (11); and a support frame (13) that is mounted on a cylinder head (15) of an engine, and that has a plurality of bearing holes (25) which are formed on the same axis and into which the rolling bearings (12) fitted, and that rotatably supports the camshaft (11) via the rolling bearings (12) that are fitted into the bearing holes (25). The support frame (13) is formed by connecting a plurality of split bodies (27), (28) together, and the plurality of split bodies (27), (28) includes a first split body (27) on which a plurality of first concave portions (29) that form half of the bearing holes (25) is integrally formed, and a second split body (28) on which a plurality of second concave portions (30) that form the other half of the bearing holes (25) is integrally formed.

    摘要: Among a plurality of bearings that rotatably support a camshaft (1), the bearing closest to a pulley (P) is a rolling bearing (4), and the other bearings are plain bearings (3). The rolling bearing (4) is formed of a roller bearing portion (5) that has a first outer ring raceway surface (51) and a plurality of cylindrical rollers (53) that roll on the first outer ring raceway surface (51) and a ball bearing portion (6) that is arranged next to the roller bearing portion (5) in an axial direction and that has a second outer ring raceway surface (61) and a plurality of balls (63) that roll on the second outer ring raceway surface (61). The first outer ring raceway surface (51) and the second outer ring raceway surface (61) are formed on the inner peripheral surface (7a) of a single outer ring (7).
