A wiper arm, has a joint part (1) and a wiper rod (2), in which the wiper rod (2) is guided in the joint part (1) in a guide region (1.2) by means of spaced-apart retaining faces (3, 4), and the retaining faces (3, 4) in the installed state fit over at least a fractional portion (7.2) of the wiper rod (2), in which the retaining faces (3, 4) taper conically toward one another, in which the wiper rod (2) has a conically tapering partial region (7), and in which the outer dimensions of the partial region (7), in a first portion, are less than the inside diameter between the retaining faces (3, 4) and, in a second portion (7.2), a distance between edges of the retaining faces (3, 4) is larger than a distance between the first portion (7.1) and the retaining faces (3, 4).
