Abstract

A camshaft housing (40) includes two longitudinal frame bars (42) and lateral frame bars (50). The longitudinal frame bars (42) extend in the axial direction of a camshaft (100). The lateral frame bars (50) extend between the longitudinal frame bars (42). A bearing portion (52) is arranged in each of the lateral frame bars (50) to rotationally support the camshaft (100). Each lateral frame bar (50) has a bolt hole (54) to receive a bolt (B) that is inserted through the bolt hole (54) to fix the camshaft housing (40) to a cylinder head body (20). The bolt hole (54) extends through the lateral frame bar (50) and is arranged on the outer side of the bearing portion (52) in the longitudinal direction of the lateral frame bar (50). Each longitudinal frame bar (42) has a vibration reducing portion (60). The cross-sectional area of the longitudinal frame bar (42) gradually changes in the longitudinal direction of the longitudinal frame bar (42).
