Abstract

Le problème décrit par la présente invention est de fournir un manche à balai avec lequel un jeu ne se produit pas et la sensation de fonctionnement est souple lorsque la tige de commande est dans un état vertical. La solution selon l'invention porte sur un manche à balai (80) comportant des mécanismes de rappel élastique (K1, K2) et un mécanisme de rappel magnétique (60), les mécanismes de rappel élastique (K1, K2) et le mécanisme de rappel magnétique (60) se complétant entre eux pour augmenter ou diminuer une force de rappel provoquée par l'angle d'inclinaison d'une tige de commande (5), ce qui permet d'uniformiser sensiblement la variation de la force de rappel. Par conséquent, le manche à balai (80) peut conférer une sensation de fonctionnement souple sans variation importante de la force de rappel par rapport à l'inclinaison de la tige de commande (5). De plus, étant donné que la force de rappel du mécanisme de rappel magnétique (60) est maximisée lorsque la tige de commande (5) est dans l'état vertical, l'état vertical peut être maintenu sans génération d'agitation ou de jeu.
