  FIG. 7 is a left side view of the accessory socket 20 with the lid member 30 closed to the second position. In the accessory socket 20 according to the present embodiment, when driven in the closing direction only by the urging force of the torsion spring 48, particularly when the power plug inserted into the opening 41 is only pulled out and does not touch the lid member 30. However, it is characterized in that it is configured to stop at the second position before the first position and to exhibit the sealing performance by the O-ring 44 to some extent. This is realized by forming a second groove 36 (see FIGS. 8 and 10) formed adjacent to the first groove 35 on the inner peripheral surface 39 of the lid member 30.

  8 is a cross-sectional view taken along line 8-8 in FIG. A first groove 35 parallel to the end surface 37 of the edge portion and the ceiling surface 38 of the lid member 30 and a second groove 36 adjacent to the first groove 35 are formed on the inner peripheral surface 39 of the lid member 30. Has been. Both the first groove 35 and the second groove 36 have circular cross sections 35 a and 36 a that engage with the O-ring 44. However, the second groove 36 provided to be inclined with respect to the first groove 35 has an arc cross section 36 a adjacent to the first groove 35 at a position farthest from the rotation shaft 43, while It is configured to overlap the first groove 35 at the closest position.

  With this configuration, when the lid member 30 is driven in the closing direction only by the urging force of the torsion spring 48, the O-ring 44 is engaged with the second groove 36, so that the second position before the fully closed position is reached. It will be held at the position (half-open position). That is, in the configuration without the second groove 36, when the lid member 30 is closed only by the urging force of the torsion spring 48, the airtightness is maintained with a gap left between the O-ring 44 and the first groove. However, by providing the second groove 36 according to the present embodiment, the O-ring 44 engages with the second groove 36 even when the lid member 30 is closed only by the urging force of the torsion spring 48. Thus, effective waterproofness and dustproofness are ensured.

FIG. 9 is an explanatory diagram of the structure around the opening 41 of the socket body 40. This figure shows a state in which the lid member 30 is held at the second position. As described above, the O-ring 44 is attached to the groove 51 having a U-shaped cross section formed in the small diameter portion 45 of the socket body 40. In the present embodiment, a rotating shaft 43 that rotatably supports the lid member 30 is disposed at a position separated from the O-ring 44. Specifically, the rotating shaft 43 is disposed offset from the O-ring 44 radially outward by a distance A and offset from the O-ring 44 toward the socket body 40 by a distance B.

  According to this configuration, when the lid member 30 is closed, it is possible to delay the timing at which the O-ring 44 on the side close to the rotation shaft 43 contacts the second groove 36. As a result, the entire peripheral area of the O-ring 44 is engaged with the second groove 36 at the same time as much as possible so that the contact condition becomes uniform, and the sealing performance by the second groove 36 is efficiently generated. It becomes possible.

  FIG. 10 is an explanatory view showing an engagement relationship between the O-ring 44 and the two grooves 35 and 36.

Can be waterproof and dustproof. From this point, it is necessary to push the lid member 30 further in the closing direction in order to obtain the fully closed position where the O-ring 44 engages with the first groove 35 and to obtain a better sealing property.

  A convex portion 50 is formed between the first groove 35 and the second groove 36 to give a resistance force when the lid member 30 is pushed from the second position to the first position. When the lid member 30 is further pushed in from the second position, a resistance force is generated when the O-ring 44 is deformed by the convex portion 50, and when the convex portion 50 is overcome and the first position is reached, a good sealing property is obtained. Will be. Moreover, the convex part 50 also produces the resistance force at the time of opening the 1st cover member 30, and prevents the cover member 30 from opening unintentionally.

  According to this configuration, when closing the lid member 30, the O-ring 44 climbs over the convex portion 50 between the first groove 35 and the second groove 36, so that the lid member 30 is closed. It becomes possible to give a sense of moderation. Thereby, it is possible to determine whether or not the lid member 30 is completely closed with a fingertip sense, and it is possible to prompt the occupant to push in the lid member 30. Further, it can be determined from the appearance whether or not the lid member 30 is completely closed.
