徴とする作業車における油圧経路切換装置。At the neutral position of the directional control valve, the oil path from the directional control valve installed in the blade-side hydraulic path that operates the blade joins the attachment-side hydraulic path to which an attachment working part such as a breaker belongs, which is different from the blade-side hydraulic path. At the very least, the pressure oil from the brake/de side hydraulic path is forced to be fed to the attachment working part such as the breaker, together with the pressure oil from the attachment side hydraulic path, by switching operation of a directional control valve provided in the attachment side hydraulic path. A hydraulic path switching device for a work vehicle, characterized in that:
