    • An object of the present invention is to have high strength in the region around a tank port in a cylinder, reduce component cost, increase work efficiency, and reduce weight. A tank port (18) includes a reinforcing sheet (28), an inner member (30), and an outer member (32). The reinforcing sheet (28) is attached around a through-hole (1202) on the outer peripheral surface of a cylinder (12). The inner member (30) includes an inner fitting plate portion (3004) attached to the inner peripheral surface of the cylinder (12) and an inner cylindrical portion (3002) inserted into the through-hole (1202). The outer member (32) includes an outer cylindrical portion (3202) attached to the outer peripheral surface of the inner cylindrical portion (3002) protruding from an opening (2802) and an outer fitting plate portion (3204) attached around the opening (2802) of the reinforcing sheet (28). The entire periphery of the through-hole (1202) of the cylinder (12) is reinforced by being disposed between the inner fitting plate portion (3004) and the reinforcing sheet (28).
    • 本发明的目的在于在气缸的罐口周围的区域具有高强度,降低部件成本,提高工作效率并且减轻重量。 罐口(18)包括加强片(28),内部构件(30)和外部构件(32)。 增强片(28)安装在圆筒(12)的外周面的贯通孔(1202)的周围。 内部构件30包括附接到圆筒12的内周表面的内部配合板部分3004和插入到通孔1202中的内部圆筒形部分3002。 外侧部件32具有安装在从开口部2802突出的内侧圆筒部3002的外周面上的外侧圆筒部3202和安装在开口部2802周围的外侧嵌合板部3204, )的增强片(28)。 筒体12的贯通孔1202的整个周围通过配置在内嵌板部3004与增强片28之间而被加强。
