PROBLEM TO BE SOLVED: To provide a sealing structure capable of being mounted after assembling a device (after inserting a rotor), and capable of using an inexpensive X seal compared to an oil seal.SOLUTION: A seal groove 4 is formed at an opening end of a hole part 2 for rotor insertion of a fitting member 1; a low projection part 6 is formed at an opening end 5 of the seal groove 4; in a rotor assembly state of inserting a rotor 7 into the hole part 2, an X ring 8 is freely mounted in the seal groove 4; and in a seal mounting state of mounting the X ring 8 in the seal groove 4, the X ring 8 is prevented from being loosened at the low projection part 6.SELECTED DRAWING: Figure 1 【課題】装置を組み立てた後（回転体を挿入した後）から装着することができ、かつ、オイルシールと比較して安価なＸシールを用いることができる密封構造を提供する。【解決手段】取付部材１の回転体挿入用孔部２の開口端にシール溝４を形成すると共に、シール溝４の開口端５に低突条部６を形成して、回転体７を孔部２に挿入した回転体組付状態にて、Ｘリング８をシール溝４に装着自在とすると共に、シール溝４にＸリング８が装着されたシール装着状態ではＸリング８が低突条部６にて抜止めされる。【選択図】図１
