In 82, the operating force from the emergency operating member 76 in a direction parallel to the advancing / retreating direction of the rod 21 is transferred from the restricted position to the deregulation position, and the restricting member 28 is orthogonal to the advancing / retreating direction of the rod 21. The force to actuate will act. At this time, the bag-shaped portion 83a of the seal rubber 83 is deformed and bent as shown in FIG. 12, and the reaction force of the bag-shaped portion 83a causes the emergency operating member 76 to return to its original position. ..

Next, the operation of the first embodiment will be described. Since the lid switchgear 20 includes a holding mechanism 68 that elastically holds at least the regulation release position of the regulation member 28, the rod 21 is in the protruding position. Even if the door is accidentally locked in this state, the regulation release position of the regulation member 28 is elastically held by the holding mechanism 68, so that the regulation member 28 does not reach the regulation position halfway. The restricting member 28 is held at the deregulation position without stopping at the position. Therefore, it is not necessary to return the door from the locked state to the unlocked state, and by moving the rod 21 to the lid closed position and then performing the locking operation, the movement of the rod 21 can be smoothly regulated, which is convenient. It can enhance the sex.

Further, at the position where the holding mechanism 68 is integrally provided with the cover 24 constituting a part of the case 22, and the restricting member 28 is in the middle of moving from the deregulation position to the regulation position side. Since the restricting member 28 is composed of the elastic member 70 attached to the restricting member 28 while abutting on the abutting portion 69 so as to urge the restricting member 28 to the deregulation position side, an increase in the number of parts is avoided. The holding mechanism 68 can be configured.

Further, between the emergency operating member 76 and the restricting member 28 included in the lid opening / closing device 20, the operating force from the emergency operating member 76 in the direction parallel to the advancing / retreating direction of the rod 21 is directed from the restricted position to the restricted release position. Since the operating force acting direction changing mechanism 84 that converts the regulating member 28 into the operating force is provided, when the emergency operating member 76 is operated in a direction parallel to the advancing / retreating direction of the rod 21, the operating force acting direction changing mechanism 84 is provided. The regulating member 28 operates in a direction orthogonal to the advancing / retreating direction of the rod 21 from the regulated position to the deregulation position, and makes the operating direction of the emergency operating member 76 parallel to the advancing / retreating direction of the rod 21. As a result, the assembly workability can be improved without widening the insertion hole 25 provided in the vehicle body outer plate 15.

Further, the operating force acting direction changing mechanism 84 is formed on the emergency operating member 76 by inclining the protrusion 82 integrally projecting with the restricting member 28 so as to diagonally intersect the operating direction of the restricting member 28. Since it is composed of a cam portion 85 that abuts on the protrusion 82, the operating force action direction changing mechanism 84 is configured with a simple and compact structure that avoids an increase in the number of parts by eliminating the need to use a link mechanism or the like. Therefore, the lid opening / closing device 20 can be downsized.

Further, the emergency operation member 76 is provided with a guide hole 87 extending long in the moving direction thereof, and the case 22 guides the movement of the emergency operation member 76 and regulates the moving end of the emergency operation member 76. Since the guide protrusion 88 that is inserted into the guide hole 87 is projected in this way, the guide protrusion 88 that is projected into the case 22 is simply inserted into the guide hole 87 provided in the emergency operation member 76. The configuration can guide the movement of the emergency operating member 76 and regulate the moving end of the emergency operating member 76.
