## Abstract

The present invention provides a protective construction of a fuel pump. The protective construction includes a pump shield, disposed on an internal-combustion engine, wherein a specified interval exists at a carriage side of a vehicle in opposite to a high-pressure fuel pump and the pump shield overlaps the high-pressure fuel pump in a front and rear direction. The pump shield includes: a base portion having a width increasing gradually towards the high-pressure fuel pump; a left protective arm portion and a right protective arm portion, extending diagonally and integrally extend upwards from a specified location of the base portion to the side of the high-pressure fuel pump, wherein an interval between the left protective arm portion and the right protective arm portion increases gradually towards the high-pressure fuel pump, and a beam portion, integrally extending between the left protective arm portion and the right protective arm portion.
