The purpose of the present invention is, in a drowsiness negation device, to impart a stimulus to a site which is strongly affected by arousal. Provided is a drowsiness negation device, comprising a drive control unit which imparts a stimulus to a user by drive controlling: a first stimulus imparting device group, further comprising a first stimulus imparting device which imparts a stimulus to the user's latissimus dorsi tendon part, and a second stimulus imparting device which imparts a stimulus to a first skin part which is a skin portion which is associated with a first kinesthetic illusion which is induced in the supplementary motor area which is activated by the stimulus upon the latissimus dorsi tendon part and which covers a skeletal muscle which is a congenerous muscle of the latissimus dorsi； and/or a second stimulus imparting device group, further comprising a third stimulus imparting device which imparts a stimulus to the user's gluteus medius tendon part, and a fourth stimulus imparting device which imparts a stimulus to a second skin part which is a skin portion which is associated with a second kinesthetic illusion which is induced in the supplementary motor area which is activated by the stimulus upon the gluteus medius tendon part and which covers a skeletal muscle which is a congenerous muscle of the gluteus medius tendon.Le but de la présente invention est, dans un dispositif de négation de somnolence, de transmettre un stimulus à un site qui est fortement affecté par un arousal. L'invention concerne un dispositif anti-somnolence, comprenant une unité de commande d'entraînement qui applique un stimulus à un utilisateur par entraînement commandant: un premier groupe de dispositifs conférant un stimulus, comprenant en outre un premier dispositif conférant un stimulus qui applique un stimulus à la partie du tendon de muscle grand dorsal ( latissius dorso ) de l'utilisateur, et un second dispositif conférant un stimulus qui applique un stimulus à une p
