This gear meshes with a rack formed on the side surface of the control rod 43c, and when the electric motor is operated by electric power supplied from a vehicle battery (not shown), the gear rotates. The control rod 43c moves forward and backward by being converted into a force in the forward and 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 detecting that the ignition is ON, supplies an electric current to the drive mechanism 43b so that the control rod 43c moves backward (moves forward). Is detected, the current is supplied to the drive mechanism 43b so that the control rod 43c advances (moves backward). The control of the drive mechanism 43b is not limited to the above-described control, and the control rod 43c can be moved forward and backward based on an arbitrary signal.

  The front end portion (rear end portion) of the control rod 43c protrudes rearward from the casing 43a. A protruding piece 43d that fits into the fitting recess 41c of the lock pin 41 is formed at the tip of the control rod 43c. When the lid 20 is in the closed state, the protrusion 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 forward / backward direction is transmitted to the lock pin 41.

  Further, the base end portion (front end portion) of the control rod 43c protrudes forward from the casing 43a. An engagement 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 is exhausted. The lock manual release mechanism 44 is provided on the rotation member 44a, which is rotatably supported with respect to the housing 10, and is separated from the rotation center of the rotation member 44a in one radial direction. A lock pin engagement portion 44b that engages with the lock pin 41, and a long operation portion 44c that is provided on the rotation member 44a away from the rotation center of the rotation member 44a in the other radial direction and is pulled. And have. The rotating member 44a is supported by a support shaft portion 10c that protrudes in the vertical direction from the outer surface of the housing 10.

  The lock pin engagement portion 44b protrudes from the rotation member 44a in one radial direction of the rotation center, and comes into contact with the engagement pin portion 43e of the control rod 43c from the rear side. Thus, since the control rod 43c is integrated with the lock pin 41, the lock pin 41 and the lock pin engaging portion 44b are engaged via the control rod 43c.

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

  The pulling direction of the operation unit 44c and the retreating direction of the lock pin 41 may be the same direction. In this case, for example, the base end portion of the operation portion 44c is formed integrally with the lock pin engaging portion 44b, and the operation 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 part 44b moves in the forward direction, the engaging pin part 43e is engaged with the lock pin engaging part 44b, so that a backward force acts on the control rod 43c. Since the lock pin 41 is engaged with the control rod 43c, a force in the backward direction acts on the lock pin 41, and the lock pin 41 moves backward. As a result, the lock pin 41 is detached from the stopper portion 14 and the lock is released.

(Effect of embodiment)
As described above, according to the fuel lid device 1 according to this embodiment, when the arm 30 is rotated around the support shaft 31a and the lid 20 is in the open state, the elastic portion of the housing 11 is formed on the intermediate portion 33 of the arm 30. The material C contacts. 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 and the housing protruding portion 13b of the housing 10, a large bonding area is secured between the elastic material C and the housing 10, and a strong adhesive force is obtained. Therefore, even if the arm 30 is in strong contact with the elastic material C, the elastic material C is unlikely to be detached from the housing 10.

  Further, when the lock pin 41 of the locking device 40 advances when 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, when a force acts on the lid 20 in the opening direction, the lid 20 slightly moves in the opening direction. When the lid 20 moves in the opening direction, the engaging convex portion 14b of the stopper portion 14 fits and engages with the engaging concave portion 41a of the lock pin 41, so that the lock pin 41 does not retreat unexpectedly, and the lid 20 The locked state is maintained.

  In a state where the engaging convex portion 14b of the stopper portion 14 is fitted and engaged with the engaging concave portion 41a of the lock pin 41, the engaging convex portion 14b and the engaging concave portion 41a are inclined so as not to come out of contact with each other. Therefore, the fitting state of the engaging convex portion 14b and the engaging concave portion 41a can be maintained.

  When the lock pin 41 moves forward and backward in a normal time 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.

  In addition, when the electric actuator 43 breaks down, the lock member 41 can be manually retracted by releasing the lock by rotating the rotation member 44a by pulling the operation unit 44c by hand. it can.
