摘要

A sealing element seals gap between connector terminal surrounded by cylindrical wall (2), and case wall (1A). A rib (5A) for positioning is formed at outer periphery of cylindrical wall (2). The notches (25) are formed in cylindrical wall (22) of sealing element holder (20), and a notch (25A) for positioning among notches (25) is wider than others. The rib is insertable in the notch (25A) and cylindrical wall (22) expands when the rib is inserted in notch other than notch (25A).
