Waterproof grommet

A waterproof grommet comprising:

• a first member having a first sealing part formed on the inner surface of at least one through-hole through which an electrical wire that connects to a contact is passed, the first sealing part being formed to adhere tightly to the electrical wire;
• a second member having a second sealing part formed on the outer circumferential surface of the through-hole, the second sealing part being formed to adhere tightly to a connector housing;
• the first member having the first sealing part is formed from an elastic material that has a lower hardness than the hardness of the second member having the second sealing part;
• the first member and the second member are formed as an integral unit by two-color molding;
• the second member has at least one recessed part which is used to align a contact cavity formed in the connector housing with the through-hole by engaging with at least one protruding part formed on a waterproof grommet supporting member;
• and
• the recessed part(s) are formed so that the distances between the recessed part(s) and the outer circumferential surface of the through-hole(s) are substantially the same, and so that the distances between the recessed part(s) and the through-hole(s) are substantially the same.

• the second member having an insertion opening with a tapered shape and disposed at the insertion entry point for the contact in the through-hole, and has at least one recessed part which is used to align a contact cavity formed in the connector housing with the through-hole by engaging with at least one protruding part formed on a waterproof grommet supporting member;
