LID BODY ATTACHING/DETACHING STRUCTURE AND STORAGE CONTAINER

PROBLEM TO BE SOLVED: To continue an excellent locking state by suppressing abrasion of a structure for locking.SOLUTION: In a lid body attaching/detaching structure in which an outer peripheral surface 31a of a cylindrical overlapped wall part 31 of a body 13 and an inner peripheral surface 51a of a cylindrical overlapped wall part 51 of a lid body 15 face each other, a regulation part 32 which protrudes in the thickness direction and regulates relative movement of the inner peripheral surface 51a of the lid body 15 and a locking reception part 33 which protrudes in the thickness direction are formed on the outer peripheral surface 31a of the body 13, a sliding part 52 which protrudes in the thickness direction and slides on the regulation part 32 and a locking protrusion 53 which protrudes in the thickness direction and is locked to the locking reception part 33 are formed on the inner peripheral surface 51a of the lid body 15, motion conversion surfaces 34, 54 which can convert the straight motion of putting the lid body 15 on the body 13 into the motion for causing the locking protrusion 53 to approach the locking reception part 33 and be directed to the lower part of the locking reception part 33 are formed on the regulation part 32 and the sliding part 52, and the locking protrusion 53 is locked to the locking reception part 33 from below.SELECTED DRAWING: Figure 1 【課題】係止のための構造の摩耗を抑制できて良好な係止状態が持続できるようにする。【解決手段】本体１３の円筒形の重合壁部３１の外周面３１ａと、蓋体１５の円筒形の重合壁部５１の内周面５１ａが相対向する蓋体着脱構造において、本体１３の外周面３１ａに、厚み方向に張り出して蓋体１５の内周面５１ａの相対移動を規制する規制部３２と、厚み方向に張り出す係止受け部３３を形成する。蓋体１５の内周面５１ａに、厚み方向に張り出して規制部３２の上を摺動する摺動部５２と、厚み方向に張り出して係止受け部３３に係止する係止突部５３を形成する。規制部３２と摺動部５２に、本体１３に蓋体１５を被せる直線動を、係止突部５３を係止受け部３３に接近させるとともに係止受け部３３の下部に指向させる動きに変換可能にする運動変換面３４，５４を形成して、係止突部５３を係止受け部３３に下から係止させる蓋体着脱構造。【選択図】図１
