The device has an attachment part (11) driven to pivot, a wiper arm (12) with a wiper blade carrier on one end and connected to the attachment element at the other end via a joint (14) whose axis lies in the pivoting direction and a tension spring (21) fixed to the wiper arm and to the attachment part. The spring is fixed at one end using a spring-elastic element whose spring hardness is greater than that of the spring.
