LOCK PIN, LOCK STRUCTURE, ATTACHMENT, AND LOCK METHOD
To improve durability of a lock pin.SOLUTION: A lock pin 30 includes: a metallic body 31; a rotation section 34 which is formed of an elastic material, is rotatably mounted around a rotary shaft 35 crossing a longitudinal direction of the lock pin 30 at one end 37 of the body 31, and can project ahead of the one end 37 by rotation; and a block 32 which is detachably mounted in the body 31. When the block 32 is mounted in the body 31, a projection 36 presses the rotation section 34 in a rotation direction and rotates the rotation section with respect to the body 31.SELECTED DRAWING: Figure 10
【課題】ロックピンの耐久性を向上させる。【解決手段】ロックピン３０は、金属製の本体３１と、弾性材料で形成され、本体３１の一端部３７にロックピン３０の長手方向と交差する回転軸３５まわりで回動可能に取り付けられ、回動によって一端部３７より先に突出可能な回動部３４と、本体３１に着脱可能に取り付けられるブロック３２と、を有する。ブロック３２は、本体３１に取り付けられたとき、突起３６が回動部３４を回動方向に押圧して本体３１に対して回動させる。【選択図】図１０
