Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an in-vehicle rotating lid device mounted on a vehicle.

2. Description of the Related Art Drink holders for holding cans, PET bottles, etc., and console boxes for accommodating various articles are known as a type of functional member mounted on a vehicle. This type of functional member has the function of holding a can or a PET bottle or containing an article.
Some devices with these functional members have a lid member for closing and opening the functional member as required. Hereinafter, a device having this type of lid member and functional member will be referred to as a lid device. Further, of the functional members in the lid device, a region that is closed or opened by the lid member is called an opening/closing region.

As a method for changing the position of the lid member between the closed position in which the opening/closing area is closed and the open position in which the opening/closing area is opened, uniaxial or multiaxial rotation, sliding, or the like can be used.

Patent Literature 1 discloses a lid member that rotates between an open position and a closed position.
Specifically, an example of Patent Document 1 introduces a cup holder having a lid member as a lid member. The cup holder has a holder, a lid member, a spring and a locking member. The lid member has an arm, and the arm is rotatably axially connected to each of the left and right side portions of the holder by a shaft pin. The mechanism rotates the cover member with respect to the holder. A spring is engaged between the arm of the lid member and the side surface of the holder, and the biasing force of the spring always biases the lid member in the rotational direction to open it. Furthermore, the lid member is held in a closed state by a locking member. The locking member releases the holding state by pushing the lid member.

According to the technique introduced in Patent Document 1, the lid member, that is, the cover member, automatically changes its position from the closed position to the open position, that is, from the closed state to the open state by the biasing force of the spring.

By the way, since the space in the vehicle interior is limited, it may be difficult for the occupant to move freely in the vehicle interior.
According to the in-vehicle rotatable lid device as introduced in Patent Document 1, the lid member automatically changes position from the closed position to the open position. Therefore, the occupant can open the lid member of the in-vehicle rotating lid device from the closed position to the open position with a relatively small movement. In other words, it can be said that the lid device introduced in Patent Document 1 is excellent in operability during the opening operation.

However, even in the in-vehicle rotating lid device introduced in Patent Document 1, the closing operation of the lid member from the open position to the closed position still needs to be manually performed by the passenger. Therefore, this type of in-vehicle rotating lid device still has room for improvement in terms of operability.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a vehicle-mounted rotating lid device with improved operability.

The in-vehicle rotating lid device of the present invention includes:
a functional member having an opening/closing region;
a lid member having a lid rotation shaft that is pivotally supported with respect to the functional member, the lid member rotating to change its position between a closed position that closes the opening/closing area and an open position that opens the opening/closing area;
a drive element that changes between a closed drive state for driving the lid member to the closed position and an open drive state for driving the lid member to the open position;
The drive element further pushes the lid member in the closed position in the closing direction to change the state from the closed drive state to the open drive state, and pushes the lid member in the open position further in the open direction. In this vehicle-mounted rotary lid device, the state is changed from the open drive state to the close drive state by doing so.

The vehicle-mounted rotating lid device of the present invention is excellent in operability.

Hereinafter, the in-vehicle rotating lid device of the present invention will be specifically described. In this specification, the vehicle-mounted rotating lid device of the present invention may be abbreviated as the lid device of the present invention, the lid device of the embodiment, or the like, as necessary.
Also, unless otherwise stated, any numerical range "x to y" recited herein includes the lower limit x and the upper limit y. Further, a numerical range can be configured by arbitrarily combining these upper and lower limits and the numerical values listed in the embodiments. Furthermore, numerical values arbitrarily selected from within the numerical range can be used as upper and lower numerical values.

The lid device of the invention comprises a functional member, a lid member and a drive element.

The functional member is a member having some function and has an opening/closing region that is opened and closed by the lid member. The lid member rotates between an open position and a closed position, closing the opening/closing area of the functional member at the closed position, and opening the opening/closing area at the open position. When the lid member opens the closure area, the interior of the functional member becomes accessible to the outside world. Also, when the lid member closes the open/close area, the interior of the functional member becomes inaccessible from the outside world. The functional member and the lid member in the lid device of the present invention should satisfy such a relationship.

For example, if the lid device of the present invention is a drink holder, the functional member has a holder portion for containing and holding a beverage container, and the lid member has a closed position that closes the opening of the holder portion and the opening of the holder portion. The open position may be changed. In this case, the opening of the holder part becomes the opening/closing area of the functional member.

Further, for example, when the lid device of the present invention is a drink holder, the lid member may have a holder portion, and the functional member may have a housing portion for housing the holder portion of the lid member. In this case, the position of the lid member may be changed by rotation between a closed position that closes the opening of the accommodating portion of the functional member and an open position that opens the opening of the accommodating portion. For example, the lid member may close the opening with the holder portion, or may have a lid portion that closes the opening separately from the holder portion. That is, in this case, the opening of the accommodating portion, not the opening of the holder portion, becomes the opening/closing area of the functional member.
As will be described later, the lid member is rotatable further in the opening direction than at the open position and further rotatable in the closing direction than at the closed position. That is, the lid member in the lid device of the present invention changes its position over a slightly wider area including the area between the open position and the closed position.

As described above, when the lid member has the lid portion and the holder portion, the lid portion of the lid member closes the opening/closing region of the functional member at the closed position, and opens the opening/closing region at the open position. The position of the holder is not particularly limited.

The holder part may, for example, be housed in the housing part of the functional member when the lid part is in the closed position, and be confined inside the housing part by the lid part. Also in this case, when the lid portion is changed to the open position and the accommodating portion is opened, the holder portion accommodated inside the accommodating portion becomes accessible from the outside. That is, at this time, the occupant can store and hold an article such as a container in the holder portion, and can take out the article stored and held in the holder portion.

Alternatively, for example, a lid member having a holder portion on the rear surface side of the lid portion may be used. In such a case, when the lid closes the opening/closing area of the functional member in the closed position, the holder may be exposed to the outside of the opening/closing area.
In other words, the lid member having the holder portion on the back side of the lid portion rotates 180° to form the first structure in which the opening/closing region of the functional member is closed by the lid portion and the holder portion is accommodated in the accommodating portion of the functional member. The position can be changed between a closed position and a second closed position in which the opening/closing region of the functional member is closed by the lid portion and the holder portion is exposed to the outside of the opening/closing region. The lid in the lid device can be said to have two closed positions.
In this type of lid device, when the lid member is in the open position between the first closed position and the second closed position, part of the opening/closing region of the functional member is opened and accommodated. The part or the holder part housed in the housing part becomes accessible from the outside world.

As described above, the lid member in the lid device of the present invention may change its position by rotating between the first closed position, the open position and the second closed position. The rotation angle of the lid member is not particularly limited, and may be a relatively large angle of 180° or more or a relatively small angle of 90° or less. Considering the space saving of the lid device, it is preferable that the rotation angle of the lid member is small so that the mechanism for rotating the lid member, that is, the drive element described later can be made compact. Preferred ranges of the rotation angle between the open position and the closed position of the lid member include ranges of 120° or less, 100° or less, 90° or less, and less than 90°.

The lid member may open the opening/closing region of the functional member at the open position, and the position of the lid member at the open position is not particularly limited. For example, in the open position the lid member may protrude outwardly beyond the opening and closing area of the functional member. However, since the lid device of the present invention is installed in a vehicle interior where space is limited, in consideration of space saving, the amount of protrusion of the lid member outward from the opening/closing region of the functional member in the open position is small. is preferred. Specifically, at least a portion of the lid member is preferably arranged inside the functional member or arranged laterally of the functional member and inward of the opening/closing region in the open position. Of course, it is particularly preferred if the lid is arranged entirely inside the functional element in the open position or laterally of the functional element and inward of the opening and closing area.

The functional member is not limited to the above-described holder portion and storage portion, and various types of components such as a table for placing items such as communication equipment and bags, a monitor for a car navigation system, a car navigation system, an audio system, and the like. An operation panel or the like for operating an in-vehicle device may be used. In these cases, the opening/closing area of the functional member is the surface of the table or the screen of the monitor or operation panel. The opening/closing area of the functional member can also be regarded as an area of the functional member that is accessed by the occupant.

If at least part of the lid member is arranged inside the functional member, the functional member may have a receptacle for receiving the lid member. The accommodating portion for accommodating the lid member may also serve as the holder portion provided on the functional member or the accommodating portion for accommodating the holder portion provided on the lid member, or may be provided separately from these. can be

The drive element changes states between a closed drive state for driving the lid member to the closed position and an open drive state for driving the lid member to the open position. That is, the drive element drives the lid member to the closed position in the closed drive state, and drives the lid member to the open position in the open drive state.
In the lid device of the present invention, in order to change the state of the drive element from the closed drive state to the open drive state, the lid member in the closed position must be rotated in the direction in which the lid member rotates from the open position to the closed position, that is, Press further in the closing direction. Further, in order to change the state of the drive element from the open driving state to the closing driving state, the lid member in the open position is further pressed in the direction in which the lid member rotates from the closed position to the open position, that is, in the opening direction. do.

According to such a driving element, the lid member is driven to automatically open and close the opening/closing region of the functional member simply by pressing the lid member by the passenger. Therefore, it can be said that the lid device of the present invention having the functional member, the lid member and the driving element described above is excellent in operability.

In addition to the above-described open driving state and closing driving state, the driving element also has a state between the opening driving state and the closing driving state, that is, a neutral state in which the lid member is not driven to either the open position or the closed position. very good

If the driving element assumes the above-described neutral state when the lid member is in the open position or when the lid member is in the closed position, there is no need to provide a locking element for locking the lid member in the open position or the closed position. , the lid member can be maintained in an open or closed position. The drive element may be in the neutral state either when the lid member is in the open position or in the closed position, or may be in the neutral state in both cases.

The two lock bodies 61 and 62 have symmetrical shapes with respect to the plane extending in the vertical direction and the horizontal direction shown in FIG. The two locking bodies 61 and 62 can also be said to have substantially the same rod shape. Each of the two lock bodies 61 and 62 has a shaft portion 61s at one longitudinal end thereof, and a hook-shaped lock engaging portion 65 at the other longitudinal end thereof. Also, the two lock biasing members 64 are each a torsion coil spring.

The shaft portions 61s of the lock bodies 61 and 62 are inserted through the holes 22h of the corresponding lock shaft support portions 22, respectively, so that the lock bodies 61 and 62 are pivotally supported on the corresponding lock shaft support portions 22, respectively.
Moreover, although not illustrated in particular. Each lock biasing member 64 is mounted on the shaft portion 61s of the corresponding lock bodies 61 and 62, respectively. One end of the lock biasing member 64 is fixed to the lock shaft support portion 22 and the other end is fixed to the lock bodies 61 and 62 . The lock biasing member 64 is mounted in a contracted state between the lock shaft support portion 22 provided in the functional member 1 and the lock bodies 61 and 62 pivotally supported by the lock shaft support portion 22. 62 are each pressed towards the functional element 1 .
One locking body 61 is arranged rearward of the link rotating shaft 57 , and the other locking body 62 is arranged forward of the link rotating shaft 57 .

The link auxiliary element 66 has a presser portion 67 and a presser urging member 68 . The pressing portion 67 has a substantially plate shape, is arranged on the right side of the link member 55 , and is pivotally supported by the link member 55 . Specifically, the pressing portion 67 is provided with blind hole-like hole portions 67 h at positions corresponding to the two shaft portions 55 s of the link member 55 . The pressing portion 67 is pivotally supported by the link member 55 by inserting the shaft portion 55s into the hole portion 67h.
The presser urging member 68 is made of a torsion coil spring, and is attached to the presser portion 67 while accumulating an urging force. 55 is pressed toward the housing portion 15 .

The opening/closing auxiliary biasing member 69 is made of a torsion coil spring and is mounted on the biasing support portion 21 of the housing portion 15 . Both ends of the opening/closing auxiliary biasing member 69 are free ends. As shown in FIG. 4, one end and the other end of the opening/closing auxiliary biasing member 69 respectively overlap the front side portion or the rear side portion of the opening/closing restricting pin groove 25 . One end of the opening/closing assisting biasing member 69 is arranged behind the opening/closing restricting pin 43 , and the other end of the opening/closing assisting biasing member 69 is arranged forward of the opening/closing restricting pin 43 . The accommodating portion 15 is provided with two return restricting pins (not shown). One of the return restricting pins is arranged forward of the one end of the opening/closing auxiliary biasing member 69 , and the other of the return restricting pins is arranged rearward of the other end of the opening/closing auxiliary biasing member 69 . The open/close restricting pin 43 and the return restricting pin are positioned so as not to interfere with each other.

The operation of the lid device of Example 1 will be described below.

The lid member 3 in the lid device of the first embodiment rotates to change its position between the closed position shown in FIGS. 2 to 4 and the open position shown in FIG. The lid member 3 is rotatable about the lid rotating shaft 34 in a clockwise opening direction and a counterclockwise closing direction. The lid member 3 is also positioned at the closed limit position (see FIG. 7), which is further rotated in the closing direction than the closed position, and the open limit position (see FIG. 11), which is further rotated in the opening direction than the open position. can change. Therefore, it can be said that the lid member 3 substantially changes its position by turning between the closed limit position and the open limit position, and during that time changes its position by turning between the closed position and the open position.
The link member 55 rotates between the first link position shown in FIGS. 2-4, 11 and 12 and the second link position shown in FIGS. 7-9. The link member 55 at the first link position rotates counterclockwise and changes position to the second link position. Also, the link member 55 at the second link position rotates clockwise and changes position to the first link position.

As shown in FIGS. 2-4, in the closed position, the lid portion 30 of the lid member 3 closes the opening/closing area 11 of the housing portion 15 . At this time, the holder portion 31 of the lid member 3 is located below the lid portion 30 , and the lid portion 30 and the holder portion 31 are housed inside the housing portion 15 . That is, at this time, the entire lid member 3 is housed inside the functional member 1 rather than the opening/closing region 11 .

As shown in FIGS. 2 and 3, the link member 55 at the first link position has the pressure receiving portion 58 directed upward and forward, and the link side holding portion 56 directed downward and rearward. At this time, it can be said that the link member 55 directs the pressure receiving portion 58 toward the opening direction side and the link side holding portion 56 toward the closing direction side. The pressure receiving portion 58 is arranged at the front end portion of the pressure receiving guide portion 19 . As shown in FIG. 2, an opening provided in the lid member 3 is provided on the front side of the pressure receiving portion 58, that is, on the rear side in the rotation direction of the link member 55 from the first link position to the second link position. An input unit 41 is arranged.

As shown in FIG. 3 , at this time, the lock engaging portion 65 of the first lock body 61 engages with the lock groove 59 of the link member 55 . Therefore, at this time, the link member 55 is locked at the first link position by being locked by the lock engaging portion 65 .

At this time, as shown in FIG. 2 , the lid side holding portion 40 provided on the lid member 3 is arranged on the rear side portion of the urging guide portion 20 . On the other hand, the link side holding portion 56 is arranged below and slightly forward of the lid side holding portion 40 . Therefore, the link side end portion 52 of the opening/closing biasing element 50 is also arranged below and slightly forward of the lid side end portion 51 . The link-side end portion 52 is located on the front side in the closing direction with respect to the straight line Ls passing through the lid-side end portion 51 and the lid rotation shaft 34 .

A slight biasing force is accumulated in the opening/closing biasing element 50, and the link side end portion 52 is located on the front side in the closing direction with respect to the straight line Ls passing through the lid side end portion 51 and the lid rotation shaft 34. do. Further, the link member 55 that holds the link side end portion 52 of the opening/closing urging element 50 is locked as described above and the rotation thereof is stopped. Therefore, the biasing force of the opening/closing biasing element 50 acts on the lid member 3 via the lid-side end portion 51 of the opening/closing biasing element 50 . Specifically, at this time, the opening/closing urging element 50 attempts to deform in the direction of releasing the urging force, that is, in the contracting direction, so that the lid member 3 is pulled in in the closing direction. Due to the action of the opening/closing urging element 50, the lid member 3 is difficult to rotate in the opening direction at this time, and can be held in the closed position even if the lid member 3 rattles during running of the vehicle.

In addition, as shown in FIG. 4 , one end of the opening/closing auxiliary biasing member 69 is located behind the opening/closing restricting pin 43 provided on the lid member 3 . At this time, the opening/closing auxiliary biasing member 69 is in an intermediate state in which the biasing force is not accumulated. In addition, a return restricting pin (not shown) is arranged on the front side of one end and the rear side of the other end of the opening/closing auxiliary biasing member 69 . Therefore, when a counterclockwise force acts on one end of the opening/closing assisting biasing member 69, that is, a force in the closing direction, the opening/closing assisting biasing member 69 is elastically deformed in the closing direction to accumulate the biasing force. Similarly, even if a clockwise force acts on the other end of the opening/closing assisting biasing member 69, that is, in the opening direction, the opening/closing assisting biasing member 69 is elastically deformed in the closing direction to accumulate the biasing force. Therefore, when the lid member 3 is in the closed position, the opening/closing assisting biasing member 69 restricts the counterclockwise positional change of the opening/closing restricting pin 43, thereby further rotating the lid member 3 in the counterclockwise direction, that is, in the closing direction. regulate movement. Due to the action of the opening/closing assisting urging member 69, the lid member 3 is held at the closed position without being further rotated in the closing direction than at the closed position.
Similarly, when the lid member 3 is at the open position described later, the opening/closing auxiliary biasing member 69 regulates the clockwise positional change of the opening/closing regulation pin 43, and thus the lid member 3 moves further clockwise, that is, in the opening direction. to regulate the rotation of Therefore, due to the action of the opening/closing auxiliary urging member 69, the lid member 3 is held at the open position without being able to rotate further in the opening direction than at the open position.

As shown in FIG. 5, when the occupant presses downward on the pressing end 32 at the rear end of the lid member 3, a force in the closing direction is further applied to the lid member 3 in the closed position. When the pressing force from the occupant at this time exceeds the biasing force of the opening/closing assisting biasing member 69, the lid member 3 is further rotated in the closing direction from the closed position toward the closed limit position shown in FIG.

When the lid member 3 is further rotated in the closing direction from the closed position, as shown in FIG. The first lock body 61 is pressed to the side away from the accommodating portion 15, that is, the right side in FIG. Then, the first lock body 61 rotates rightward in FIG. 1 against the biasing force of the lock biasing member 64 . As a result, the lock engaging portion 65 of the first locking body 61 is separated from the locking groove 59 of the link member 55, the locking of the link member 55 by the first locking body 61 is released, and the link member 55 is rotatable. Become.

At this time, when the lid member 3 further rotates in the closing direction from the closed position, the opening input portion 41 provided on the lid member 3 presses the pressure receiving portion 58 of the link member 55 counterclockwise. Then, the link member 55 rotates counterclockwise about the link rotation shaft 57 from the first link position shown in FIGS. 2 to 4 to the second link position shown in FIG. Then, as shown in FIG. 5, the link side holding portion 56 of the link member 55 also changes its position counterclockwise. Since the lid member 3 rotates from the closed position toward the closed limit position, the lid side holding portion 40 of the lid member 3 is still on the rear end side of the urging guide portion 20 . Accordingly, at this time, the link side holding portion 56 changes its position in the direction away from the lid side holding portion 40 . Then, the lid side end portion 51 of the opening/closing urging element 50 held by the lid side holding portion 40 and the link side end portion 52 of the opening/closing urging element 50 held by the link side holding portion 56 are separated to open and close. Biasing element 50 extends to build up a biasing force.

At this time, the opening/closing auxiliary biasing member 69 shown in FIG. 4 is pressed in the closing direction by the opening/closing restricting pin 43 and accumulates biasing force.

Since the link member 55 changes its position while being pressed toward the housing portion 15 by the link auxiliary element 66, even if the extension of the opening/closing biasing element 50 acts on the link member 55 in a direction other than the rotational direction, The link member 55 operates stably.

When the occupant further presses the lid member 3 in the closing direction, the opening force portion 41 provided on the lid member 3 further presses the pressure receiving portion 58 of the link member 55 counterclockwise, thereby causing the link member 55 to rotate. It further rotates counterclockwise around the driving shaft 57 . Then, as shown in FIG. 6, the link-side end portion 52 of the opening/closing biasing element 50 held by the link-side holding portion 56 of the link member 55 is aligned with the straight line passing through the lid-side end portion 51 and the lid rotation shaft 34 . is placed on Ls. At this time, the opening/closing urging element 50 and the lid member 3 are balanced, and the opening/closing urging element 50 accumulates the urging force and does not urge the lid member 3 in either the opening direction or the closing direction.

When the occupant presses the lid member 3 further in the closing direction, the link member 55 rotates further counterclockwise around the link rotation shaft 57, and the drive element 5 is brought into the open drive state.
Specifically, at this time, as shown in FIG. 7, the link-side end portion 52 of the opening/closing biasing element 50 is arranged on the front side in the opening direction with respect to the straight line Ls. The link member 55 is arranged at the second link position. In the second link position, the link member 55 directs the pressure receiving portion 58 upward and rearward, and directs the link side holding portion 56 downward and forward. At this time, it can be said that the link member 55 directs the pressure receiving portion 58 toward the closing direction side and the link side holding portion 56 toward the opening direction side.

If the link side end portion 52 of the opening/closing biasing element 50 is arranged on the front side in the opening direction with respect to the straight line Ls, the balance between the opening/closing biasing element 50 and the lid member 3 is lost as shown in FIG. As a result, the opening/closing biasing element 50 contracts to release its biasing force. Therefore, the lid-side end portion 51 of the opening/closing biasing element 50 moves forward in the biasing guide portion 20, and the biasing force of the opening/closing biasing element 50 pulls the lid member 3 in the opening direction. Therefore, at this time, the opening/closing biasing element 50 biases the lid member 3 in the opening direction, and the lid member 3 starts rotating toward the open position. The lid member 3 is also urged to rotate when the pressing force from the occupant disappears and the urging force accumulated in the opening/closing auxiliary urging member 69 is released.

Note that when the link member 55 changes its position to the second link position shown in FIG. Therefore, at this time, the link member 55 is locked at the second link position, and only the lid member 3 rotates from the closed limit position shown in FIG. 7 toward the open position shown in FIG.

When the lid member 3 rotates to the open position shown in FIG. 9, the rear side of the pressure receiving portion 58 of the link member 55, that is, the rear side of the link member 55 in the rotation direction from the second link position to the first link position. On the side, a closing input 42 provided on the lid member 3 is arranged.

When the lid member 3 in the lid device of the first embodiment is at the open position, some biasing force remains in the opening/closing biasing element 50 . Therefore, the lid member 3 is held at the open position by the action of the opening/closing urging element 50 so as to be difficult to rotate in the closing direction.
Further, at this time, further rotation of the lid member 3 in the opening direction is restricted by the opening/closing auxiliary biasing member 69 . This also holds the lid member 3 in the open position.

When the lid member 3 is arranged at the open position, the opening/closing area 11 is opened and the holder portion 31 of the lid member 3 is exposed. Then, it becomes possible to accommodate and hold the beverage container in the holder portion 31 .

As shown in FIG. 10 , when the occupant presses downward the front upper portion of the lid member 3 in the open position, a force in the opening direction is further applied to the lid member 3 . When the pressing force at this time exceeds the biasing force of the opening/closing auxiliary biasing member 69, the lid member 3 is further rotated in the opening direction from the open position toward the open limit position shown in FIG.

When the lid member 3 is further rotated in the opening direction from the open position, the lid-side holding portion 40 provided on the lid member 3 presses the second lock body 62 toward the right side in FIG. The lock between the lock engaging portion 65 of the lock body 62 and the lock groove 59 of the link member 55 is released. Therefore, the lock of the link member 55 by the second lock body 62 is released, and the link member 55 becomes rotatable.

At this time, the lid member 3 further rotates in the opening direction from the open position, so that the closing input portion 42 provided on the lid member 3 presses the pressure receiving portion 58 of the link member 55 clockwise. Therefore, the link member 55 rotates clockwise about the link rotation shaft 57 from the second link position to the first link position. At this time, the position of the link-side holding portion 56 of the link member 55 also changes clockwise, so that the opening/closing biasing element 50 expands and accumulates biasing force. The opening/closing auxiliary biasing member 69 is also pressed by the opening/closing regulation pin 43 and accumulates biasing force.

When the lid member 3 pressed by the occupant rotates in the opening direction, the link member 55 rotates clockwise, and the link side of the opening/closing biasing element 50 held by the link side holding portion 56 of the link member 55 is opened. The end portion 52 is arranged on a straight line Ls passing through the lid-side end portion 51 and the lid rotation shaft 34, as shown in FIG. When the pressed lid member 3 further rotates in the opening direction, the link member 55 also rotates further clockwise, and the drive element 5 enters the closed drive state. At this time, as shown in FIG. 11, the link side end portion 52 of the opening/closing biasing element 50 is arranged on the front side in the closing direction with respect to the straight line Ls. Therefore, the lid member 3 is pulled in the closing direction by the biasing force of the opening/closing biasing element 50, and starts rotating toward the closed position as shown in FIG. At this time, the link member 55 is arranged at the first link position.

Thus, according to the lid device of the first embodiment, the lid member 3 biased by the opening/closing biasing element 50 automatically rotates between the open position and the closed position. The operations required by the occupant to open and close the lid member 3 are only to press the lid member 3 in the closed position and to press the lid member 3 in the open position. Therefore, it can be said that the lid device of Example 1 is excellent in operation.

The lid device of the first embodiment has the opening/closing auxiliary biasing member 69 for stably holding the lid member 3 at the open position and the closed position. Not required. For example, if the center of gravity of the lid member 3 and the biasing force of the opening/closing biasing element 50 when the lid member 3 is in the open position and the closed position are appropriately adjusted, the lid member can be opened without providing the opening/closing auxiliary biasing member 69. 3 can be stably held in the open and closed positions, respectively. Further, the opening/closing auxiliary biasing member 69 merely restricts the further rotation of the lid member 3 in the closed position in the closing direction, or restricts the further rotation of the lid member 3 in the open position in the opening direction. It is also possible to simply restrict the rotation.

The link assisting element 66 is also not essential in the lid device of the present invention. For example, by attaching a sliding member near the rotation shaft of the link member 55 or using a member with a relatively large mass as the link member 55, the sliding resistance of the link member 55 can be appropriately adjusted. Even without the element 66, the link member 55 can be stably operated.

The rotation angle between the open position and the closed position of the lid member 3 in the lid device of Example 1 is approximately 87°. According to the lid device of the first embodiment, since the lid member 3 rotates between the open position and the closed position at a relatively small angle, the lid device does not become bulky even in the open position, which saves space.

The present invention is not limited to the embodiments described above and shown in the drawings, and can be modified as appropriate without departing from the scope of the invention. Moreover, each component shown in this specification including the embodiments can be arbitrarily extracted and combined for implementation.
