A mounting structure of a liquid level detecting device for detecting a liquid level of liquid stored in a tank, the mounting structure comprising:

• a mounting object member;
• and
• the liquid level detecting device including:
• a device main body which is mounted on a mounting surface of the mounting object member;
• and
• a holder which is attached to the device main body and is rotated according to a variation of the liquid level of the liquid stored in the tank;
• wherein the mounting object member has a pair of lock portions which lock respective side portions of the device main body when the device main body is inserted between the lock portions and a pair of projections which are formed so as to face a front portion of the device main body when the device main body is inserted between the lock portions;
• wherein the device main body has a pair of hooks which are arranged in a width direction of the device main body and extend in an insertion direction where the device main body is inserted between the lock portions;
• wherein the hooks have respective claws which are locked on the respective projections from inside in the width direction of the device main body;
• and
• wherein the hooks are formed closer to the mounting surface in a thickness direction of the device main body than a holder movable area of the device main body.
