Abstract
An injection-molded body according to the present invention includes a tubular body portion, an airtight seal surface formed on a peripheral surface of the body portion near one end of the body portion, and a plurality of undercuts disposed at positions around the peripheral surface of the body portion that are closer to the end than the airtight seal surface is. The undercuts prevent a seal member mounted on the airtight seal surface from falling off, in which a clearance is formed between a peripheral wall and the undercuts. The peripheral wall defines an inner hole of the body portion, and the clearance accommodates deformation of the undercuts in radial directions.
