The control rod 43c moves forward and backward by being converted into a force in the forward / backward direction of the rod 43c.

The drive mechanism 43b can be controlled by an external control unit (not shown). The external control unit detects ON and OFF of the ignition, and when it detects that the ignition is turned ON, supplies a current to the drive mechanism 43b so that the control rod 43c moves backward (moves to the front side), while the ignition When it is detected that the control rod 43c is turned off, a current is supplied to the drive mechanism 43b so that the control rod 43c advances (moves to the rear side). The control of the drive mechanism 43b is not limited to the above-mentioned control, and the control rod 43c can be moved forward and backward based on an arbitrary signal.

The tip end (rear end) of the control rod 43c projects rearward from the casing 43a. At the tip of the control rod 43c, a projecting piece portion 43d that fits into the fitting recess 41c of the lock pin 41 is formed. When the lid 20 is in the closed state, the projecting piece portion 43d of the control rod 43c is fitted into the fitting recess 41c of the lock pin 41, whereby the control rod 43c and the lock pin 41 are integrated and the control rod 43c is integrated. The force in the advancing / retreating direction is transmitted to the lock pin 41.

Further, the base end portion (front end portion) of the control rod 43c projects forward from the casing 43a. An engaging pin portion 43e is formed at the base end portion of the control rod 43c.

The lock manual release mechanism 44 is a mechanism for manually moving the lock pin 41 in the lock release direction (forward direction) when the electric actuator 43 breaks down or the battery of the automobile runs out. The lock manual release mechanism 44 is provided on the rotating member 44a that is rotatably supported with respect to the housing 10 and the rotating member 44a that is separated from the rotation center of the rotating member 44a in one radial direction. A lock pin engaging portion 44b that engages with the lock pin 41 and a long operating portion 44c that is provided on the rotating member 44a apart from the rotation center of the rotating member 44a in the other direction in the radial direction and is pulled. And have. The rotating member 44a is supported by a support shaft portion 10c protruding in the vertical direction from the outer surface of the housing 10.

The lock pin engaging portion 44b protrudes from the rotating member 44a in one direction in the radial direction of the rotation center, and comes into contact with the engaging pin portion 43e of the control rod 43c from the rear side. As a result, the control rod 43c is integrated with the lock pin 41, so that the lock pin 41 and the lock pin engaging portion 44b are engaged with each other via the control rod 43c.

The operating portion 44c extends from the side opposite to the lock pin engaging portion 44b with the rotation center interposed therebetween. The base end portion of the operating portion 44c is integrally molded so as to have a gap 44i in the connecting portion 44h of the rotating member 44a. The gap 44i can be formed, for example, by a slit, a notch, or the like. The tip of the operation unit 44c extends into, for example, the interior of an automobile or the interior of a trunk room (not shown). A fixing portion 44d for fixing to the outer surface of the housing 10 is provided in the middle portion of the operating portion 44c. When the operating portion 44c is held by hand and pulled to the rear side, the rotating member 44a rotates around the support shaft portion 10c, and the lock pin engaging portion 44b moves forward. That is, the pulling direction of the operating portion 44c is opposite to the retracting direction of the lock pin 41.

The pulling direction of the operating portion 44c and the retracting direction of the lock pin 41 may be the same direction. In this case, for example, the base end portion of the operating portion 44c is integrally molded with the lock pin engaging portion 44b, and the operating portion 44c is pulled forward. As a result, the rotating member 44a rotates around the support shaft portion 10c, and the lock pin engaging portion 44b moves in the forward direction.

When the lock pin engaging portion 44b moves in the forward direction, the engaging pin portion 43e is engaged with the lock pin engaging portion 44b, so that a force in the backward direction acts on the control rod 43c. Since the lock pin 41 is engaged with the control rod 43c, a force in the retracting direction acts on the lock pin 41, and the lock pin 41 retracts. As a result, the lock pin 41 is released from the stopper portion 14 to release the lock.

(Action and effect of the embodiment)
As described above, according to the fuel lid device 1 according to this embodiment, when the arm 30 rotates around the support shaft 31a and the lid 20 is opened, the elasticity of the housing 11 is applied to the intermediate portion 33 of the arm 30. Material C comes into contact. When a strong force is applied to the lid 20 in the opening direction, the elastic material C is elastically deformed and the impact force is absorbed. Therefore, damage to the arm 30 and the housing 10 is suppressed.

Since the elastic material C is provided so as to cover the vertical wall portion 13a of the housing 10 and the housing protruding portion 13b, a wide adhesive area between the elastic material C and the housing 10 is secured and a strong adhesive force can be obtained. Therefore, even if the arm 30 strongly abuts on the elastic material C, the elastic material C is unlikely to come off from the housing 10.

If the lock pin 41 of the lock device 40 advances while the lid 20 is in the closed state, the lock pin 41 engages with the stopper portion 14 and the lid 20 is locked in the closed state. At this time, if a force acts on the lid 20 in the opening direction, the lid 20 moves slightly in the opening direction. When the lid 20 moves in the opening direction, the engaging convex portion 14b of the stopper portion 14 fits into and engages with the engaging concave portion 41a of the lock pin 41, so that the lock pin 41 does not suddenly retract and the lid 20 does not retract. Is kept locked.

When the engaging convex portion 14b of the stopper portion 14 is fitted into the engaging concave portion 41a of the lock pin 41 and engaged, the surfaces of the engaging convex portion 14b and the engaging concave portion 41a are inclined so as not to come off from each other. Therefore, it is possible to maintain the fitted state of the engaging convex portion 14b and the engaging concave portion 41a.

When the lock pin 41 moves forward and backward in the normal state when no force is applied to the lid 20 in the opening direction, the engaging convex portion 14b of the stopper portion 14 becomes the engaging concave portion 41a of the lock pin 41. The lock pin 41 can be smoothly moved forward and backward without being fitted.

Further, when the electric actuator 43 breaks down, the rotating member 44a can be rotated by holding and pulling the operation unit 44c by hand, and the lock pin 41 can be manually retracted to release the lock. it can.
