A caliper ( 1 ) for a disc-brake comprises two side walls ( 2 ) at a distance from each other which delimit a space ( 3 ) to accommodate a portion of a brake disc in which one of said two side walls ( 2 ) comprises means ( 4 ) for attaching the caliper ( 1 ) to a vehicle so that it is integral in rotation and in translation. The side walls ( 2 ) are connected to each other by means of a connecting structure ( 5 ) which straddles the disc space ( 3 ). Each of the side walls ( 2 ) delimits at least one seating ( 6 ) capable of accommodating a pad ( 7 ) and the caliper ( 1 ) comprises thrust means ( 8 ) to clamp the pads ( 7 ) against the brake disc, in which the thrust means ( 8 ) are secured to the side walls ( 2 ) in such a way that the latter absorb the entire clamping force and the seatings ( 6 ) are capable of securing the pads ( 7 ) in such a way that the side walls ( 2 ) also absorb the entire braking moment applicable by the pads ( 7 ) to the brake disc by friction. The connecting structure ( 5 ) comprises one or more shells ( 10, 11 ), arc-shaped or arranged along an arc, connected so as to be integral with both the side walls ( 2 ) along one of their outer circumferential edges ( 12 ) and the slenderness of these one more shells ( 10, 11 ) expressed as the ratio of thickness to circumferential extension relative to an axis of rotation of the brake disc is less than 17/100.
