固定するためのボルトとナツトである。(Prior Art) Conventionally, as shown in FIGS. 3 and 4, fenders include an impact-receiving portion 1 that receives an impact load from a ship, etc., an attachment portion 2 to a wall surface 6 such as a quay, and A support part 3 made of an elastic member provided between the impact receiving part 1 and the mounting part 2 is used. Here, FIG. 3 shows an example in which the impact receiving part 1 and the supporting part 3 are formed in one area, and FIG. 4 shows an example in which the impact receiving part 1 is formed separately from steel material etc. An example of one attached to the impact receiving side 4 of the is shown. Note that 7 and 8 are bolts and nuts for fixing the mounting portion 2 to the wall surface 6.

パス９を積層して埋設することも提案されている。When attaching such a fender to a wall surface such as a quay, it is necessary to provide a certain degree of hardness to the attaching part 2 in order to facilitate the attachment. A steel plate 5 is buried in the mounting part 2, and the mounting part 2 is attached to the wall surface 6 by bolts 7 and nuts 8 protruding from a wall surface 6 such as a quay.
It was being fixed. Furthermore, as shown in a longitudinal cross-sectional view in FIG. 6, it has been proposed that instead of the iron plate 5 in FIG. 5, a plurality of canvases 9 are stacked and buried.
（発明が解決しようとする問題点）
第５゛図に示したような、従来の防舷材の取付部では、
鉄板５を埋設しているため、重量が太きくなり、岸壁等

た場合、破損し、海中へ落下する等の問題があり、船舶
を安全に接舷できなくなる場合があった。(Problems to be solved by the invention) In the conventional fender attachment part as shown in Fig. 5,
Since the iron plate 5 is buried, it is heavy and difficult to attach to a wall surface 6 such as a quay, and water may seep into the inside of the mounting part 2 during long-term use. ,
As a result of the iron plate 5 corroding, separation occurs between the iron plate 5 and the rubber member that constitutes the mounting part 2, and when a ship or the like comes into contact with it, there is a problem that it will break and fall into the sea. In some cases, ships could not be safely berthed alongside.

への固定が不安定になるという問題が生じる。On the other hand, in the case where the fender is attached as shown in Fig. 6, since the campus 9 is buried, there are fewer problems like the above-mentioned case when iron plates are used, but the large load from the impact receiving part 1 is In addition, it requires a lot of man-hours to laminate and bond the canvas, which increases the cost.Furthermore, if a slight scratch occurs on the mounting part 2 during use, Due to capillary action, water infiltrates into the canvas 9 buried in the mounting part 2, causing separation between the canvas 9 and the rubber member constituting the mounting part 2, causing the wall surface 6
A problem arises in that the fixation to is unstable.
