The invention relates to a spring arm device (1) for a motor vehicle, comprising two flanges (2) arranged at a distance from each other and which are made of a first fiber composite material (4) having fibers (6) each oriented in a longitudinal direction (5) of the flanges (2). The spring arm device (1) also comprises a web (3) which connects the flanges (2) and is made of a second fiber composite material (7) having the fibers (8) oriented at positive angles to the longitudinal directions (5) of the flanges (2). The spring arm device (1) can be fastened in end regions (15) opposite to each other to vehicle parts as part of a wheel suspension. The end regions (15) comprise end segments (14) of the two flanges (2) associated with each other and each comprise an end segment (9) of the web (3) that connects the end segments (14) of the flanges (2). Respective forces applied to the spring arm device (1) in the longitudinal direction (5) by means of the end regions (15) can be transmitted by means of the flanges (2). By means of a spring force, the flanges (2) counteract deformation of the spring arm device (1) caused by forces acting in a normal direction (16) of the web (3). Forces acting on the spring arm device (1) in a transverse direction (13) are transmitted from the web (3) to the end regions (15).
