Provided is a glove-type power assist device which has no uncomfortable feeling when in use, is easy to put on, and convenient to use in daily life. The glove-type power assist device of the present invention comprises: a glove (10) which comprises a finger insertion portion (11) an elastic tube (20) fixed on a dorsal side of the finger insertion portion (11) and restricted in stretching along a longitudinal direction on the side and a fluid supply medium supplying a fluid to the elastic tube (20). The glove-type power assist device supports a bending movement of a finger by supplying the fluid to the elastic tube (20), stretching the dorsal side more than a ventral side of the elastic tube (20), and bending the elastic tube (20) toward the ventral side. Actually the whole of the glove (10) is formed of an elastic base material (13) which has elasticity, and a side line (L1) forming a boundary between the dorsal and ventral sides of the finger insertion portion (11) has an inelastic structure restricting the bending toward the longitudinal direction of the finger insertion portion (11) so that the elastic tube (20) is bent centering around a bending point of a joint of the finger.Linvention concerne un dispositif assisté de type gant qui na pas de sensation inconfortable lors de lutilisation, qui est facile à enfiler et qui est pratique à utiliser dans la vie de tous les jours.
