Mounting tool with plurality of ring band portions with concave portions and notches for clamping an injector

A mounting tool for mounting a cylindrically-shaped injector on a cylinder head of an engine by being engaged with the injector connected to a fuel pipe, and urging the injector toward the cylinder head, wherein the mounting tool includes a single metallic plate having a thickness that thereby defines an axial direction of the mounting tool, the mounting tool being shaped to accommodate the cylindrically-shaped injector, thereby defining a circumferential direction of the mounting tool, and a radial direction of the mounting tool as perpendicular to the axial direction and the circumferential direction, the mounting tool comprising:

• a first band portion being formed in a ring shape so as to surround an outer circumference of the injector, and including a first slit formed therein to disconnect the first band portion in the circumferential direction of the mounting tool;
• a second band portion being formed in a ring shape so as to surround the outer circumference of the injector, including a second slit formed therein to disconnect the second band portion in the circumferential direction of the mounting tool, and being arranged adjacent to the first band portion in the axial direction of the first band portion;
• and
• plural elastic band portions that connect the first band portion and the second band portion in the axial direction,
• wherein the first band portion comprises first concave portions on circumferential sides of portions thereof connected to the elastic band portions, the first concave portions being concaved in the axial direction,
• wherein the second band portion comprises second concave portions on circumferential sides of portions thereof connected to the elastic band portions, the second concave portions being concaved in the axial direction,
• wherein an edge portion of the first band portion includes a first notch,
• wherein an edge portion of the second band portion includes a second notch, and
• wherein, when viewed in, the axial direction:
• the first concave portions and the first notch are arranged along the circumferential direction so as not to overlap with each other;
• and
• the second concave portions and the second notch are arranged along the circumferential direction so as not to overlap with each other.
