Specifically, as shown in FIG. 1, the lid opening / closing device 1 is an example of a device that controls the opening / closing operation of the lid 3.

  The lid 3 is an example of a closing body that opens and closes a fuel filler port (not shown) of the vehicle. The fuel filler port is an example of an opening. The fuel filler port is provided on the outer plate (not shown) of the vehicle. The lid 3 is attached to the outer plate via the hinge portion 3A. The lid 3 is rotatable with respect to the outer plate with an imaginary line orthogonal to the paper surface as a rotation center line.

2. Configuration of Lid Opening / Closing Device 2.1 Outline of Lid Opening / Closing Device As shown in FIG. 2, the lid opening / closing device includes at least a rod device 5, a locking device 7, a locked body 9, an interlocking mechanism 11, and the like. Prepare The rod device 5 is a device for controlling the opening / closing operation of the lid 3.

  The lock device 7 is a device for restricting the operation of the rod device 5. The locked body 9 is a member provided on the lid body 3. The interlocking mechanism 11 is a mechanism that displaces the locked body 9 according to the operating state of the rod device 5.

2.2 Configuration of Rod Device As shown in FIG. 3, the rod device 5 includes at least a push rod 51, a rod casing 52, an alternating mechanism 55, and the like.

<Push rod>
The push rod 51 is a rod-shaped member that is displaced between the protruding position (see FIG. 4) and the storage position (see FIG. 5). Each time the push rod 51 receives a pressing force F (see FIGS. 4 and 5), the push rod 51 is alternately displaced between the projecting position and the retracted position.

  That is, when the push rod 51 receives the pressing force F when it is in the protruding position, it is displaced to the storage position by the pressing force F. When the push rod 51 receives the pressing force F when it is in the retracted position, it is displaced to the projecting position by the elastic force of the spring 55A (see FIG. 3).

  The protruding position is a position where a part of the push rod 51 protrudes from the rod casing 52, as shown in FIG. The storage position is a position where at least a part of the push rod 51 is stored in the rod casing 52, as shown in FIG.

  The protruding position is an example of the first position. The storage position is an example of the second position. The protruding position and the retracted position are displaced in a direction parallel to the central axis Lp of the push rod 51. The pressing force F is a force including a component parallel to the central axis Lp. The pressing force F acts on the push rod 51 via the lid body 3 and the locked body 9.

  The rod casing 52 is a tubular member having an insertion hole (not shown) into which the push rod 51 is inserted so as to be retractable. The cross-sectional shape of the insertion hole is a shape that can restrict the push rod 51 from rotating around the central axis Lp.

  The cross-sectional shape is, for example, a substantially D shape. The substantially D-shaped cross-sectional shape is a shape in which the outer edge shape has one arc portion and one straight line portion connecting the ends of the arc portion. A flat portion (not shown) is provided at a portion of the push rod 51 corresponding to the straight portion.

  Therefore, each time the push rod 51 receives the pressing force F, the push rod 51 is reciprocally displaced in a direction parallel to the central axis Lp without rotating between the projecting position and the retracted position around the central axis Lp. That is, the plane portion constitutes a regulation portion that regulates the rotation of the push rod 51.

<Koban mechanism>
The alternating mechanism 55 is a mechanism for displacing the push rod 51 in an alternating manner. As shown in FIG. 3, the alternation mechanism 55 has at least a spring 55A, a first cam 55B, a second cam 55C, a restricting cylinder 55D, a shaft member 55E, and the like.

  The spring 55A is a spring capable of exhibiting an elastic force directed upward in the plane of FIG. “Upward in the plane of FIG. 8” is the direction from the storage position side to the protruding position side. Hereinafter, this direction will be referred to as a “projection direction D1”. The direction opposite to the projecting direction D1 is referred to as "retracting direction D2".

  As shown in FIG. 6, a shaft member 55E is rotatably inserted into the first cam 55B and the second cam 55C. The shaft member 55E has a common central axis line with the central axis line Lp, and is integrated with the push rod 51 by a fixing method such as press fitting.

  That is, the first cam 55B and the second cam 55C are integrated with the push rod 51 in a rotatable state about the central axis Lp. At least one (three in the present embodiment) protrusions 55F are provided on the outer peripheral surface of the first cam 55B.

  At least one protrusion 55G is also provided on the outer peripheral surface of the second cam 55C. The number of protrusions 55G according to the present embodiment is the same as the number of protrusions 55F. Each of the protrusions 55F and 55G protrudes from the outer peripheral surface in a direction orthogonal to the central axis Lp.

  As shown in FIG. 3, the outer peripheral wall 55H of the regulation cylinder 55D is provided with the same number of groove portions 55J as the protrusion portions 55G. The groove portions 55J extend to the end portion of the regulation cylinder 55D in parallel with the central axis Lp.

  Each of the plurality of protrusions 55F is displaceable in the groove 55J along the extending direction of the groove 55J while being fitted in each of the plurality of grooves 55J (see FIGS. 6 to 8). That is, the first cam 55B is displaced parallel to the central axis Lp direction without rotating around the central axis Lp.

  Each of the plurality of protrusions 55G can be displaced between a state in which the protrusion 55G is fitted into any of the plurality of grooves 55J (see FIG. 6) and a state in which the protrusion 55G is separated from the groove 55J (see FIG. 8). That is, in a state in which each of the protrusions 55G is fitted in any of the grooves 55J, the second cam 55C is displaced in parallel in the central axis Lp direction without rotating around the central axis Lp.

  In a state in which each protrusion 55G is separated from the groove 55J, the second cam 55C is rotatable about the central axis Lp. At least one engaging protrusion 55K capable of engaging with each protrusion 55G is provided at the end of the regulation cylinder 55D, that is, at the open end side in the extending direction of each groove 55J.

  Each engagement protrusion 55K is a protrusion protruding from the end of the regulation cylinder 55D in the storage direction D2. The rotation of the second cam 55C is restricted in a state in which any one of the protrusions 55G is caught by and engaged with any one of the engagement protrusions 55K (hereinafter, referred to as an engagement state).

  The root position of each engaging protrusion 55K is displaced toward the protruding direction D1 with respect to the extending end of each groove 55J in the extending direction. The spring 55A constantly presses the second cam 55C in the protruding direction D1. Therefore, in the state shown in FIG. 8, the elastic force of the spring 55A functions as a force for maintaining the engagement state between the protrusion 55G and the engagement protrusion 55K.

  As shown in FIG. 6, the first cam 55B and the second cam 55C can exhibit the function of converting the pressing force F in the storage direction D2 into the rotational force Fr. The rotational force Fr is a force that rotates the second cam 55C in the direction of the arrow.

  That is, the first cam 55B is provided with at least one inclined surface 55L (a plurality of inclined surfaces in the present embodiment). At least one inclined surface 55M (a plurality of inclined surfaces in the present embodiment) is provided on the second cam 55C.

  The inclined surfaces 55L and 55M are surfaces inclined with respect to the direction of the pressing force F. The inclination directions of the inclined surfaces 55L and 55M are such that the component force of the pressing force F generated on the inclined surface 55M becomes the rotational force Fr when the inclined surface 55L and the inclined surface 55M come into contact with each other.

<Operation of the police box mechanism>
The alternating mechanism 55 displaces the push rod 51 between the protruding position and the retracted position each time the pressing force F acts on the push rod 51. When the push rod 51 is in the protruding position, the alternating mechanism 55 is in the state shown in FIG.

  In the state shown in FIG. 6, that is, when the pressing force F acts on the push rod 51 in the protruding position, the plurality of protrusions 55F and the plurality of protrusions 55G are fitted in any of the plurality of grooves 55J. , The pressing force F, that is, the storage direction D2.

  When each of the plurality of protrusions 55G reaches the open end in the extending direction of each groove 55J (see FIG. 7), each protrusion 55G rotates about the central axis Lp by the rotational force Fr acting on the second cam 55C.

  As a result, one of the protrusions 55G engages with one of the engagement protrusions 55K to be in the engaged state (see FIG. 8). At this time, since the engaged state is maintained by the elastic force of the spring 55A, the push rod 51 is maintained in the retracted state.

  In the state shown in FIG. 8, that is, when the pressing force F acts on the push rod 51 in the storage position, the second cam 55C is displaced in the storage direction D2, and the respective projections 55G are disengaged from the respective engagement projections 55K.

  At this time, due to the rotational force Fr acting on the second cam 55C, each protrusion 55G rotates around the central axis Lp along the guide 55N (see FIG. 7). Therefore, each protrusion 55G is guided to the open end in the extending direction of one of the grooves 55J.

  Then, when the pressing force F disappears, the plurality of protrusions 55F and the plurality of protrusions 55G are displaced in the protrusion direction D1 by the elastic force of the spring 55A while being fitted in any of the plurality of grooves 55J. Therefore, the push rod 51 returns to the protruding position.

  The guide portion 55N is an inclined surface provided at the end portion of the restriction cylinder 55D. The inclination of the guide portion 55N is the same as the inclination of the inclined surfaces 55L and 55M. As shown in FIG. 7, the top 55P of each protrusion 55G has a smooth curved surface.
