Waterproof connector and device with connector

A waterproof connector comprising:

• a connector body configured to be attached to a through hole by inserting a part of the connector body into the through hole, the through hole penetrating through an outer wall of a device and including a tapered opening, the tapered opening being an opening portion on an outer side of the device, an opening diameter of the opening portion being larger on the outer side of the device than on an inner side of the device such that the opening diameter decreases toward the inner side of the device;
• and
• a sealing member having a ring shape and having a flexibility, the sealing member being configured to seal a space between an outer circumferential face of the connector body and an inner circumferential face of the tapered opening to provide waterproofness with respect to the through hole, wherein
• the sealing member includes
• a tube-shaped inner tube portion configured to closely contact with the outer circumferential face of the connector body, and
• an outer tube portion which surrounds the inner tube portion in a circumferential direction on a rear side in an insertion direction in which the outer tube portion is inserted into the tapered opening, which has an opening diameter larger than the inner tube portion, and which is formed integral with the inner tube portion on a front side in the insertion direction,
• the connector body includes a holding projection, and
• the holding projection is configured to be inserted between the inner tube portion and the outer tube portion from the rear side in the insertion direction and is configured to push the outer tube portion against the inner circumferential face of the tapered opening when the sealing member is received between the outer circumferential face of the connector body and the inner circumferential face of the tapered opening.
