Vehicle lighting device with an optical element pressed against a light source support

A motor vehicle lighting device comprising:

• a housing and an outer lens closing a front opening of the housing and transparent to allow light rays emitted by the lighting device to pass through the outer lens;
• a light source support in the housing to which a light source is fixed or configured to be fixed;
• an optical element configured to deflect the light rays emitted by the light source;
• a bearing member fixed to the housing, the optical element being fixed relative to the light source by being at least partly gripped between the light source support and the bearing member;
• and
• at least one elastic means gripped between the bearing member and the optical element and configured to be elastically deformable in a direction from the bearing member toward the optical element.
