As shown in FIG. 2A, the switch unit 70 is schematically configured to include a light emitting element 72 connected to the wire 38 side and a light receiving element 74 connected to the display unit 83 side. The light emitting element 72 is an element that converts an electrical signal into light, for example. The light emitting element 72 is, for example, a light emitting diode. The light receiving element 74 is, for example, an element that converts light into an electrical signal. As an example, the light receiving element 74 is a photodiode. In the switch unit 70, the light emitting element 72 and the light receiving element 74 are sealed in a package that shields light.

  One end of the light emitting element 72 is electrically connected to a power source that applies a voltage via a resistor 78, and the other end is electrically connected to the wire 38 via a wiring 76 and a crimping member 52. The light receiving element 74 has one end electrically connected to the display unit 83 and the other end grounded via the vehicle body 90.

When the microswitch 40 is turned on, the switch unit 70 emits light from the light emitting element 72 to which a voltage is applied via the resistor 78, and the light receiving element 74 receives this light emission, and is applied to the display unit 83. A signal S ₂ based on the voltage is configured to flow through the display unit 83 and the light receiving element 74.

The light emitting element 830 is, for example, a light emitting diode. For example, as illustrated in FIG. 2D, “Fuel Lid OPEND” is printed on the surface of the printing unit 831.

  The display unit 83 is configured to notify when the fuel lid 10 is in an open state, that is, to notify the operator that the fuel lid 10 is open. Accordingly, when the fuel lid 10 is in the open state, the electronic circuit 20 is closed, so that the light emitting element 830 emits light and illuminates the printing unit 831 from the back side. Further, in the display unit 83, when the fuel lid 10 is in the closed state, the electronic circuit 20 is opened, so that the light emitting element 830 does not emit light and the printing unit 831 is not illuminated.

  As shown in FIG. 2D, the display unit 83 makes it easy to recognize the lighting of the display unit 83 when the operator moves his line of sight to the start button 81 in order to start the engine of the vehicle 9. The start switch 80 is disposed in the vicinity of the start button 81.

(Operation)
The operator performs an operation of pulling the operation unit 60 to refuel. By this operation, the wire 38 is moved to the right side of the paper surface of FIG. With this movement, the lock pin 31 inserted into the opening 120 of the fuel lid 10 and holding the closed state of the fuel lid 10 moves together with the wire 38 and comes out of the opening 120.

  Since the fuel lid 10 is always applied with an elastic force so as to be opened by the spring 16, the elastic force of the spring 16 is applied to the fuel lid 10 via the end portion 14 after the lock pin 31 is removed from the opening 120. It becomes an open state.

When the fuel lid 10 is in the open state, the contact between the tip 121 of the fuel lid 10 and the lever 40a of the micro switch 40 is released, so that the micro switch 40 is turned on. When the micro switch 40 is turned on, since the electronic circuit 20 is closed, it signals S ₁ based on the voltage applied via the resistor 78 propagates the light emitting element 72, the wires 38 and micro switch 40 of the switch section 70, the light emitting element 72 emits light.

The light receiving element 74 of the switch unit 70 receives the light emitted from the light emitting element 72, and a signal S ₂ based on the voltage applied to the light emitting element 830 of the display unit 83 propagates through the light emitting element 830 and the light receiving element 74. The display unit 83 emits light.

  Subsequently, when the operator finishes refueling and closes the fuel lid 10, the tip 121 of the fuel lid 10 comes into contact with the lock pin 31, and the lock pin 31 is moved in the right direction on the paper surface of FIG. By this movement, the spring 32 extends and accumulates an elastic force in a direction in which the lock pin 31 protrudes into the recess 92.

  When the front end 121 of the fuel lid 10 moves the lock pin 31 and pushes the button 40b through the lever 40a of the microswitch 40, the microswitch 40 is turned off. When the micro switch 40 is turned off, the lock pin 31 is fitted into the opening 120 by the elastic force of the spring 32 in the left direction in FIG. 2A, and the fuel lid 10 is closed.

When the fuel lid 10 is micro switch 40 is turned off together with the closed state, since the electronic circuit 20 to open, will not signal S ₁ and the signal S ₂ flows, emission of the display unit 83 is stopped.

(Effect of embodiment)
The fuel filler door opening and closing device 1 according to the present embodiment can reduce the cost by reducing the wiring. Specifically, the fuel filler door opening and closing device 1 uses the wire 38 as a part of the electronic circuit 20 including the micro switch 40 and the switch unit 70, and therefore wiring other than the wire is provided between the micro switch and the switch unit. Compared with the case of connecting with the switch 70, the wiring for connecting the microswitch 40 and the switch unit 70 is not necessary, and the cost is reduced.

  The fuel filler door opening and closing device 1 is configured such that when the fuel lid 10 is in an open state, the display unit 83 emits light and notifies the user, so that the operator can easily recognize that the fuel lid 10 is in an open state.

  The fuel filler door opening / closing device 1 suppresses power consumption as compared to the case where the micro switch is turned on in the closed state because the micro switch 40 is turned on when the fuel lid 10 is in the open state and the display unit 83 emits light. be able to.

Fuel supply port door opening and closing device 1, since the switch section 70 is composed of a light-emitting element 72 and the light receiving element 74, an effect on the light emission of the display unit 83 even if the signal S ₁ is affected by noise or the like by the wire 38 or the like Hard to give.

  In the fuel filler door opening and closing device 1, since the micro switch 40 and the switch unit 70 are electrically connected to the wire 38 by the crimping member 50 and the crimping member 52, the continuity is maintained as compared with the case where the wiring is directly attached to the wire. Easy to do and reliable.

  Since the display part 83 of the fuel filler door opening / closing device 1 is disposed near the start switch 80 of the vehicle 9, when the operator presses the start button 81, the opening / closing state of the fuel lid 10 can be confirmed by a small line of sight movement. it can.

  As a modification of the above-described embodiment, the start switch 80 may be provided as a configuration including the fuel filler door opening / closing device 1.

  As another modification, when the start switch 80 includes the light emitting unit 82, the fuel filler door opening / closing device 1 may use the light emitting unit 82 as a notification unit. As an example, the light emitting unit 82 is turned on by changing the light emission color in the ACC mode and the ON mode. This ACC mode is a mode in which, for example, the audio of the vehicle 9 can be used with the engine stopped. The ON mode is a mode in which, for example, the engine is started and all electric systems can be used. When the light emitting unit 82 of the start switch 80 is used as the notification unit, light is emitted in a color different from at least the ACC mode and the ON mode.

  As another modified example, the fuel filler door opening / closing device 1 may include a sound output unit in the start switch 80, and the sound output unit may be used as a notification unit. In this case, as an example, the notification unit is configured to output a warning sound when the start button 81 is pressed. For example, the warning sound is output for a short time before and after the engine is started.
