A powdery seasoning prepared by drying and powdering a seasoned liquid, said seasoned liquid being obtained by enzymatically digesting in the presence of sodium chloride a protein-containing starting material that is derived from wheat and/or soybean, characterized by having an inorganic material concentration of not more than 50,000 ppm； and a method for manufacturing the same. A powdery seasoning prepared by drying and powdering a seasoned liquid, said seasoned liquid being obtained by enzymatically digesting in the presence of sodium chloride a protein-containing starting material that is derived from wheat and/or soybean, characterized by having an inorganic material concentration of not more than 50,000 ppm； and a method for manufacturing the same. The present invention addresses the problem of providing a gear shift operation mechanism that improves the operability of an operation pedal for steplessly shifting a rotational power in both a forward and reverse direction, as well as a work vehicle provided with this gear shift operation mechanism. This gear shift operation mechanism (60) is provided with a gear shift operation shaft (113) onto which is fitted a pedal boss (112) of a pedal arm (111) proximal end side of a forward pedal (60f), an intermediate link (117) coupled via a coupling member (116) to a pedal boss (115) of a pedal arm (114) proximal end side of a backward pedal (60b), and a link shaft (119) onto which is fitted a link boss (118) of the intermediate link (117). The pedal boss (112) of the forward pedal (60f) is fixed to the gear shift operation shaft (113) and is non-rotatable relative to the gear shift operation shaft (113), whereas a pedal boss (113), which is installed on the right side of the pedal boss (112), is rotatable relative to the gear shift operation shaft (113).La presente invención se refiere a un condimento en polvo producido al secar y espolvorear un líquido sazonador obtenido al descomponer enzimáticamente una materia prima
