Abstract
In an auxiliary device mounting structure for mounting an auxiliary device (4) on a cylinder head (2), the auxiliary device such as a fuel injection pump is provided with a lower housing (42) attached to the cylinder head, and the upper housing (43) supporting the auxiliary device and attached to the lower housing so as to jointly form a housing chamber (48). An extension (51) of a camshaft (37) extends into the housing chamber, and is fitted with a cam (61) for actuating a plunger (86) of the auxiliary device. A radial bearing (53, 56) for the camshaft extension is integrally formed on the first housing at a position located more inward than the axial end of the cylinder head so that the cylinder head is not required to be formed with an axial extension, and is enabled to support the auxiliary device and a bearing for the camshaft extension in a highly stable manner.
