Fuel injector device having pin retainer

An injector device comprising:

• an injector having an inlet body;
• a cup in a bottomed tubular shape and configured to hold the inlet body;
• and
• a first pin and a second pin, wherein
• the cup has a sidewall defining first apertures and second apertures,
• the first pin is inserted in the first apertures,
• the second pin is inserted in the second apertures,
• the first pin and the second pin are configured to hold the inlet body and to restrict rotation of the inlet body relative to the cup,
• the inlet body has an outer periphery defining a first recess and a second recess,
• the first pin and the second pin are fitted to the first recess and the second recess, respectively,
• the first recess extends linearly in a direction perpendicularly to the injector axis, and
• the second recess extends linearly in a direction perpendicularly to the injector axis, wherein
• the first recess is dented from an outer periphery of the inlet body radially inward, and
• the second recess is dented from the outer periphery of the inlet body radially inward, wherein
• the first recess has a cross section in an arc shape, which coincides with a part of a cross section of the first pin, and
• the second recess has a cross section in an arc shape, which coincides with a part of a cross section of the second pin.
