Since it is inclined with respect to the fitting direction of the second fitting portion 7 and the second fitting portion 7, if the inclination angle is θ (see FIG. 1), it becomes a / cos θ.

Therefore, by providing the housing tapered surface 17 and the seal tapered surface 23 on the first fitting portion 3 and the seal member 15, even if the seal member 15 has the same thickness, the seal member 15 and the seal member 15 are first fitted. The length of contact with the portion 3, that is, the contact area can be increased, and the sealing property can be improved without increasing the size of the sealing member 15.

In addition, if sufficient sealing performance can be obtained by contact between the inner circumference of the first fitting portion 3 and the outer circumference of the sealing member 15, even if the thickness of the sealing member 15 is reduced, the housing tapered surface 17 By providing the seal taper surface 23 and the seal taper surface 23, the same sealability can be obtained, and the seal member 15 can be miniaturized.

Here, the inner diameter of the seal member 15 is set to be smaller than the outer diameter of the second fitting portion 7.

Therefore, when the seal member 15 is arranged on the outer circumference of the second fitting portion 7, the tightening force of the seal member 15 is applied to the outer circumference of the second fitting portion 7, and the seal member with respect to the second fitting portion 7 is applied. The retention of 15 can be stabilized.

In such a connector 1, the housing tapered surface 17 is provided at the tip end portion 11 of the first fitting portion 3, and the seal member 15 is provided with the seal tapered surface 23 capable of contacting the housing tapered surface 17. When the first fitting portion 3 and the second fitting portion 7 are fitted, the housing tapered surface 17 and the seal tapered surface 23 are brought into contact with each other to bring the first fitting portion 3 and the second fitting portion 3 into contact with each other. It is possible to seal between 7 and 7.

In a state where the housing tapered surface 17 and the seal tapered surface 23 are in contact with each other, the outer peripheral surface 19 of the seal member 15 and the outer peripheral surface 21 of the first fitting portion 3 are substantially flush with each other. The outer peripheral surface 21 of the surface 19 and the first fitting portion 3 does not protrude, and the connector 1 can be miniaturized.

Therefore, in such a connector 1, the space between the first fitting portion 3 and the second fitting portion 7 can be sealed, and the size can be reduced.

Further, since the inner diameter of the seal member 15 is set to be smaller than the outer diameter of the second fitting portion 7, the tightening force of the seal member 15 can be applied to the second fitting portion 7, and the second fitting portion 7 can be applied.
