  • the camshaft holder according to the invention comprises bearing caps pierced with an oil passage and the shaft holder is mounted in a single assembly on the cylinder head of the internal combustion engine.
  • a camshaft holder receives at least one camshaft.
  • the camshaft is guided in rotation by means of at least two bearings, each bearing being formed by an internal cylindrical bearing secured to the periphery of the camshaft housed between two half-bearings.
  • the camshaft holder comprises a base supporting a succession of half-bearings, that is to say four half-bearings when there are four bearings. These half-bearings of the base are associated respectively with a half-bearing present on one of several successive bearing caps, that is to say four bearing caps in the case of four bearings.
  • Each bearing cap therefore has on one side a complementary half-span of a half-span of the base and each half-span of the bearing caps is removably secured to the half-span of the base, advantageously by two elements fastening through each bearing cap.
  • Each association of a half-span of the base with a half-span of the bearing cap forms an advantageously circular bearing receiving an internal cylindrical bearing secured to the periphery of the camshaft by forming a bearing.
  • One face of the camshaft holder has at its periphery an interface intended to be in contact with an interface of the cylinder head.

  • An opening for the lubricating oil is made in the cap of the front bearing of the camshaft and an opening for the lubricating oil is made in the cap of the rear bearing of the camshaft.
  • This orifice is not, however, integrated into the cylinder head, the bearing cap covering a lower half-span which, for its part, is housed in the body of the cylinder head.
