    摘要： An ink retention member (4) includes an ink retention portion (40) including ink retention grooves (43) and ink guiding grooves (44). The ink retention member (4) includes a first horizontal hole (46) penetrating radially therethrough and being in communication with an inner hole (45). The first horizontal hole (46) and the ink guiding grooves (44) are formed not to communicate with each other in a transverse cross-section. The first horizontal hole (46) is provided in a rear half portion of the ink retention portion (40). The ink retention member (4) includes a second horizontal hole (47) that is disposed forward from the first horizontal hole (46), radially penetrates therethrough, and communicates with the inner hole (45). The first horizontal hole (46) and the second horizontal hole (47) are each provided to penetrate at least one comb tooth (41) axially and communicate with the ink retention grooves (43) adjacent to the comb tooth (41).

    摘要： The present invention is a direct liquid type of writing tool including: a pen tip; a columnar ink absorbent body connected to a rear end of the pen tip; an ink tank arranged on a rear side of the ink absorbent body; and a plurality of communicating tubes for connecting the ink absorbent body and the ink tank. A front end of each of the communicating tubes is located in the ink absorbent body, and is configured to have a sloped surface facing toward an outer periphery side of the ink absorbent body. Each of the communicating tubes has an opening in the sloped surface at the front end. Each of the communicating tubes has a tip end region adjacent to the opening and extending more frontward than the opening, and the tip end region forms a pressing part configured to press inside of the ink absorbent body when each of the communicating tubes is inserted frontward from a rear end of the ink absorbent body.

    摘要翻译： 本发明是一种直接液体型书写工具，包括：笔尖; 与笔尖的后端连接的柱状的墨水吸收体; 设置在墨吸收体的后侧上的墨罐; 以及用于连接墨吸收体和墨罐的多个连通管。 每个连通管的前端位于墨吸收体中，并且构造成具有面向墨吸收体的外周侧的倾斜表面。 每个连通管在前端处的倾斜表面中具有开口。 每个连通管具有与开口相邻并且比开口更向前延伸的末端区域，并且末端区域形成按压部分，该按压部分被构造成当每个连通管从前面插入时挤压墨吸收体的内部 墨吸收体的后端。

    摘要： A pressure fluctuation buffering mechanism 180 includes a buffer space K connected to a brush 120 via a paint flow space (a paint tank 140 and a paint feeder 160) through which paint flows. The pressure fluctuation buffering mechanism 180 buffers pressure fluctuation in the paint tank 140 by the flow of paint and air between the paint flow space and the buffer space K. The pressure fluctuation buffering mechanism 180 includes: a first buffer space forming member 183 for forming a first buffer space K1 in the buffer space K; and a second buffer space forming member 184 for forming a second buffer space K2 in the buffer space K. The paint between the first buffer space K1 and the paint flow space flows more easily than the paint between the second buffer space K2 and the paint flow space.
