Description

Vehicle hood structure

technical field

The present invention relates to an improvement of a vehicle hood structure in which the upper portion of the rear portion of a front hood is covered with a hood garnish.

Background technique

A front glass is arranged behind a front hood of a vehicle such as an automobile. The front hood is obtained by stamping a metal plate, and it is difficult to require continuity with the front glass for a metal front hood, so a hood trim made of resin is attached to the rear of the front hood department. The front hood and the hood trim are thermally expanded by the heat of the engine or the heat of the outside air temperature. Since the thermal expansion coefficients of the resin hood garnish and the metal front hood are different, it is necessary to take measures against misalignment due to thermal expansion. There is known a vehicle hood structure in which such measures against thermal expansion are taken.

In the vehicle hood structure disclosed in Patent Document 1, the hood garnish is divided into left and right parts at the center in the vehicle width direction in order to avoid elongation of the hood garnish due to thermal expansion, and the left and right hood garnishes are fixed. The outer end in the vehicle width direction. When the left and right hood trims thermally expand, the expansion is absorbed by the split portion in the center portion in the vehicle width direction.

However, when the hood garnish is divided in the center portion in the vehicle width direction, the divided part is exposed, which is disadvantageous in terms of improving appearance, and the structure is complicated by providing steps in the divided part, which increases the cost of parts.
