Fixing structure

A fixing structure comprising:

• a main body that is provided in a mounting member and through which a stud bolt fixed to a mounted member is inserted from one side to the other side in an axial direction;
• a pair of first locking pieces facing each other at the main body in a width direction intersecting the axial direction, the pair of first locking pieces being locked to a bolt groove of the stud bolt inserted through the main body;
• a pair of second locking pieces facing each other at the main body in the width direction, the pair of second locking pieces being located on the other side in the axial direction with respect to the pair of first locking pieces, and the pair of second locking pieces being locked to the bolt groove of the stud bolt inserted through the main body;
• and
• a pair of deflection amount regulators facing each other at the main body in the width direction, the pair of deflection amount regulators being contactable with the pair of first locking pieces, respectively, wherein
• the main body includes:
• a pair of end face walls facing each other in the axial direction, each of the pair of end face walls including a bolt insertion hole through which the stud bolt is to be inserted;
• a pair of side face walls facing each other in the width direction, each of the pair of side face walls extending between the pair of end face walls in the axial direction;
• and
• a bolt receiving space surrounded by the pair of end face walls and the pair of side face walls, the bolt receiving space being configured to receive the stud bolt inserted through the bolt insertion holes,
• each of the pair of first locking pieces includes:
• a blade protruding from a corresponding one of the pair of side face walls toward the bolt receiving space and extending toward the other side in the axial direction, the blade being elastically deformable;
• and
• a claw protruding from the blade, the claw being locked to the bolt groove,
• each of the pair of second locking pieces includes:
• a blade protruding from a corresponding one of the pair of side face walls toward the bolt receiving space and extending toward the other side in the axial direction, the blade being elastically deformable;
• and
• a claw protruding from the blade, the claw being locked to the bolt groove,
• the blade of each of the pair of second locking pieces is fixed such that an end of the blade on the other side in the axial direction is adjacent to the bolt insertion hole of an end face wall located on the other side in the axial direction among the pair of end face walls, and
• each of the pair of deflection amount regulators protrudes from a corresponding one of the pair of side face walls toward the bolt receiving space, and each of the pair of deflection amount regulators comes into contact with a respective one of the blades of the first locking pieces to regulate a deflection amount of the blade.
