    • The present invention can easily determine a specification which includes a PTO clutch mechanism or a specification which includes no PTO clutch mechanism. According to the present invention, in a tractor which detachably mounts a PTO portion on a transmission portion, a PTO clutch mechanism is arranged in the inside of the PTO portion. Accordingly, it is possible to easily determine the specification which includes the PTO clutch mechanism or the specification which includes no PTO clutch mechanism depending on whether the PTO clutch mechanism is preliminarily assembled in the PTO portion or not in a stage that the PTO portion is assembled and, at the same time, it is possible to easily complete the assembling by merely mounting the PTO portion on the transmission portion. Further, by taking steps opposite to the above-mentioned steps, it is possible to easily perform the maintenance of the PTO clutch mechanism or the like.
    • 本发明可以容易地确定包括PTO离合器机构或不包括PTO离合器机构的规格的规格。 根据本发明,在可拆卸地将PTO部分安装在传动部分上的拖拉机中,PTO离合器机构布置在PTO部分的内部。 因此,根据PTO离合器机构是否预先组装在PTO部分中,在PTO部分组装的阶段中,可以容易地确定包括PTO离合器机构或不包括PTO离合器机构的规格的规格 同时,通过仅将PTO部分安装在传动部分上,可以容易地完成组装。 此外,通过与上述步骤相反的步骤,可以容易地执行PTO离合器机构的维护等。

    • The present invention aims at making a transmission casing compact. In the present invention, in the inside of a transmission casing, a traveling-system power transmission mechanism which is interposed between an engine and an axel, a PTO-system power transmission mechanism which is interposed between the engine and a PTO shaft, and a changeover mechanism which is interposed between both power transmission mechanisms are provided, wherein the power transmission of the PTO-system power transmission mechanism is interrupted at a middle portion thereof by the changeover mechanism and, at the same time, the changeover mechanism is allowed to perform a changeover manipulation to connect a downstream side portion of the PTO-system power transmission mechanism and a downstream side portion of the traveling-system power transmission mechanism. In this manner, it is possible to transmit the rotational speed proportional to the rotational speed of the engine to the PTO-shaft (first PTO-system power transmission) with the use of the PTO-system power transmission mechanism, while with the use of the changeover mechanism, it is possible to perform the changeover manipulation which interrupts the power transmission of the PTO-system power transmission mechanism in the middle portion thereof and, at the same time, connects the downstream-side portion of the PTO-system power transmission mechanism and the downstream-side portion of the traveling-system power transmission mechanism so as to transmit the rotational speed proportional to a vehicle speed to the PTO shaft (second PTO-system power transmission).
    • 本发明的目的在于使变速箱紧凑。 在本发明中,在变速器壳体的内部,设置有位于发动机和轴之间的行驶系动力传递机构,配置在发动机和PTO轴之间的PTO系统动力传递机构, 设置有两个动力传递机构之间的切换机构,其中PTO系统动力传递机构的动力传递在其中间部分由切换机构中断,同时允许切换机构执行 连接PTO系统动力传递机构的下游侧部分和行驶系统动力传递机构的下游侧部分的切换操作。 以这种方式,可以通过使用PTO系统动力传递机构将与发动机的转速成比例的转速传递到PTO轴(第一PTO系统动力传递),同时使用 切换机构,可以进行中断PTO系统动力传递机构的中间部分的动力传递的切换操作,并且同时连接PTO系统动力传递的下游侧部分 机构和行驶系动力传递机构的下游侧部分,以将与车速成比例的转速传递给PTO轴(第二PTO系统动力传递)。

    • An object of the present invention is to provide an adhesive resin composition which displays excellent adhesive strength on bonding to a barrier material, during initial adhesion, durable adhesion, and even after soak in fuel oil, and which also has excellent moldability. Furthermore, another object of the present is to provide an adhesive resin composition which when recycled, displays good compatible in a regrind layer with polyethylene resins and barrier materials such as saponified products of ethylene-vinyl acetate copolymers or polyamide based resins, and which is consequently capable of suppressing deterioration in the low temperature impact resistance of a multi-layer vessel containing a regrind layer. In order to achieve these objects, the present invention provides an adhesive resin composition (C) comprising (A) 100 to 5% by mass of a modified polyethylene in which an unsaturated carboxylic acid and/or an unsaturated carboxylic acid derivative unit is grafted to a high molecular weight polyethylene with a melt flow rate (MFR: temperature 190° C., loading 2.16 kg) of 0.1 to 2.0 g/10 minutes, and a density of 0.91 to 0.96 g/cm3, and (B) 0 to 95% by mass of an unmodified polyethylene with a melt flow rate (MFR: temperature 190° C., loading 2.16 kg) of 0.1 to 20 g/10 minutes, and a density of 0.86 to 0.96 g/cm3, wherein the density of the adhesive resin composition (C) is 0.925 to 0.940 g/cm3, the content of the unsaturated carboxylic acid and/or unsaturated carboxylic acid derivative unit incorporated therein is at least 0.09% by mass, and the melt flow rate (MFR: temperature 190° C., loading 2.16 kg) is from 0.1 to 2 g/10 minutes.
