Claim Text:
1. A crankshaft bearing cap which has a semi-cylindrical form, which has an axis X coinciding with an axis of the crankshaft, and comprising: diametrically opposed column-shaped fixing pillars, each column-shaped fixing pillar resting on a base portion and including an upper surface that integrates a circular support surface surrounding a through-hole, through which a fixing screw can pass, with a secondary surface for supporting a screw head, the secondary surface being a circle with two grooves removed from the circle, a center of the secondary surface being located within the through-hole formed in the support surface such that a portion of the secondary surface overlaps the support surface, the two grooves being removed from a portion of the secondary surface that does not overlap the support surface, a radius of the support surface being a same distance as a radius of the secondary surface in a direction of the axis X, and the secondary surface being offset from the support surface in a direction of an axis Y, wherein the grooves extend from the upper surface along an outer lateral surface of the pillar to where the pillar meets the base portion, the grooves being disposed outside a vertical support cylinder having a base equal to the support surface, and outside a volume defined by a transverse plane passing through axes of the fixing holes and extending symmetrically in a direction parallel to the axis X over a length.
