As shown in FIGS. 11A and 11B, the cam mechanism that causes the engaging member 30 to move toward and away from the engaged portion 9 as the operation lever 50 rotates about the lever axis O. 59 is provided. The cam mechanism 59 is formed on a cam pin 55 having a circular cross-section projecting from the back surface of the operation lever 50 and the bottom wall 13 of the lever accommodating portion 12, and the cam pin 55 is inserted through the lever axis O of the operation lever 50. It consists of a pin insertion hole 19 (corresponding to a pin insertion portion) that allows rotation around, and a cam groove 39 that is formed in the second plate portion 32 and into which the cam pin 55 is inserted.

  The pin insertion hole 19 is formed between the second contact rib 15 and the first engagement groove 16 (see FIG. 5). In addition, the cam groove 39 is formed long in a direction (vehicle width direction) orthogonal to the direction in which the engagement member 30 moves in and out (vehicle longitudinal direction).

  The pin insertion hole 19 is formed in the shape of a quarter circular arc concentric with the operation lever 50, and the cam pin 55 is in contact with the inner surface of one end in the circumferential direction of the pin insertion hole 19 (see FIG. a) and FIG. 11 (b)), and the cam pin 55 comes into contact with the inner surface of the other end in the circumferential direction of the pin insertion hole 19 to release the lock (see FIG. 12 (a) and FIG. 12 (b)). Set to

Therefore, the rotation angle of the operation lever 50 can be set to 0 degree to 90 degrees. In addition, the person who operates the lever can grasp the locked state or the unlocked state by the direction of the operation lever 50 (the direction of the knob 79), and the lid 10 can be easily attached and detached.
That is, as shown in FIG. 11 (a), the knob 79 extends in the vertical direction in the locked state, and as shown in FIG. 12 (a), in the unlocked state, the knob 79 rotates 90 degrees from the locked state. Since it is along the direction, the person who operates the lever can easily grasp the locked state or the unlocked state.

  Further, since the cam pin 55 is inserted into the pin insertion hole 19, the operation lever 50 can be prevented from moving radially outward with respect to the lever housing portion 12 of the lid 10. Can be prevented.

  As shown in FIGS. 13 and 14, a fifth rib R5 for receiving the end of the third plate portion 33 located at the stroke end on the unlocking side is provided on the lid 10, and the operation located at the stroke end on the unlocking side. A pair of sixth ribs R <b> 6 is provided on the lid 10 to receive the end surfaces (end surfaces in the direction around the lever axis O) of the second engaging portion 52 and the third engaging portion 53 of the lever 50.

  The fifth rib R5 is provided at an upper end portion of a rising portion 29 that rises from the rear surface of the lid outside the peripheral wall 14 of the lever accommodating portion 12, is located at a right angle to the rear surface of the bottom wall 13 of the lever accommodating portion 12, and is It continues to the back surface of the bottom wall 13. The sixth rib R <b> 6 is provided on the end surface of the other end portion in the circumferential direction of the first engagement groove 17 and the end surface of the other end portion in the circumferential direction of the second engagement groove 18. The sixth rib R6 that receives the second engaging portion 52 is located in the vicinity of the central portion in the vertical direction of the rising portion 29 (see FIG. 13).

  Thereby, the stroke of the engagement member 30 and the stroke of the operation lever 50 can be set with high accuracy. Further, for example, in the structure in which the fifth rib R5 and the sixth rib R6 are provided in the movable parts such as the engaging member 30 and the operating lever 50, when the operating lever 50 is rotated or when the engaging member 30 is withdrawn or retracted, There is a possibility that ribs may be caught on the parts, and the engaging member 30 and the operation lever 50 may not operate smoothly, resulting in a problem that the operability is degraded. On the other hand, according to the above configuration of the present invention, since the fifth rib R5 and the sixth rib R6 are provided on the lid 10 in the fixed state, the above problems can be avoided, and the engagement member 30 and the operation lever can be avoided. 50 can be operated smoothly and operability can be improved.

Further, as shown in FIG. 11 (b), one first engaging portion 51 of the operation lever 50 located at the stroke end on the lock side (from the peripheral portion of the operation lever 50 to the bottom wall 13 of the lever accommodating portion 12). An interference avoidance space 38 that avoids interference with the first engaging portion 51) projecting to the side is formed in a cutout shape at the inner corner portion of the second plate portion 32 and one of the first plate portions 31. ing. One first engagement portion 51 of the operation lever 50 located at the stroke end enters the interference avoidance space 38.
Thereby, interference with the 1st engaging part 51 and the 2nd plate part 32 can be avoided, and the said 1st engaging part in the thickness direction (front and back direction of the lid 10) of the lid 10 is possible. 51 and the engaging member 30 can be arrange | positioned in the same position, and a structure can be reduced in size.

As shown in FIG. 16, the leading end 34 </ b> A of the engaging portion 34 of the one first plate portion 31 and the leading end 35 </ b> A of the engaging portion 35 of the other first plate portion 31 are moved in and out of the engaging member 30 ( It is located at the same position in the vehicle longitudinal direction). The length L1 of the first plate portion 31 on the side where the interference avoidance space 38 is formed is equal to the length L2 of the other first plate portion 31 on the side where the interference avoidance space 38 is not formed. It is formed longer on the vehicle front side Fr.
For example, when the lengths of the pair of first plate portions 31 are set to be the same, the base end portion of the first plate portion 31 is caused by the formation of the interference avoidance space 38. The width D1 of the second plate portion 32 connected to (the end portion opposite to the engaging portion 34) is smaller than the width D2 of the second plate portion 32 connected to the base end portion of the other first plate portion 31. Therefore, there is a problem in that the strength of the engaging member 30 is lowered without achieving a rigidity balance.
On the other hand, according to the above configuration of the present invention, the length L1 of the first plate portion 31 on the side where the interference avoidance space portion 38 is formed is the side where the interference avoidance space portion 38 is not formed. The other first plate portion 31 is formed to be longer on the vehicle front side Fr than the length L2 of the first plate portion 31, so that the above problems can be avoided, and the rigidity balance of the engaging member 30 can be achieved. The durability of the engaging member 30 can be improved.

According to the configuration of the present invention,
As shown in FIGS. 11 (a), 11 (b), 12 (a), and 12 (b), as the operating lever 50 rotates around the lever axis O, the first engagement is performed. The engagement member 30 is opened in the quarter trim 1 while the parts 51 to the third engagement part 53 slide in the first engagement groove 16 to the third engagement groove 18 of the lever accommodating part 12 separately. The engagement portion 34, 35 of the engagement member 30 is operated in a locked state in which the engagement portion 34 is engaged with the engaged portion 9 on the quarter trim 1 side and an unlocked state in which the engagement is released. It is switched by lever 50.
The engaging member 30 is slidably supported by a support claw 23 formed on the lid 10, and the first engaging portion 51 to the third engaging portion 53 are dispersed around the operation lever 50. The first engaging groove 16 to the third engaging groove 18 are arranged and slide by being inserted and engaged with the first engaging portion 51 to the third engaging portion 53 of the operation lever 50. Since it is formed in the lever accommodating portion 12, the operation lever 50 can be assembled to the lever accommodating portion 12 without using a screw, and the screw can be omitted.
Therefore, compared with the case where the operation lever 50 is assembled to the lever accommodating portion 12 with a screw, the weight can be reduced, the number of parts can be reduced, and the assembling property can be improved because the fastening operation is unnecessary.

For example, the first engaging portion 51 to the third engaging portion 53 of the operation lever 50 are located at the same position in the direction along the lever axis O, and the first engaging groove 16 to the third engaging portion. In the structure in which the joint grooves 18 are located at the same position (“structure of the comparative example”), the first engaging portion 51 to the third engaging portion 53 and the first engaging groove 16 to the third engaging portion. There is a possibility that the engaging grooves 18 are assembled in different combinations.
On the other hand, according to the above configuration of the present invention, if the direction of the operation lever 50 relative to the lever housing portion 12 around the lever shaft O is not the correct direction, the operation lever 50 is assembled to the lever housing portion 12. Therefore, the first engagement portion 51 to the third engagement portion 53 and the first engagement groove 16 to the third engagement groove 18 can be assembled in a correct combination, and an assembly failure is prevented. be able to.
For example, in the structure of the comparative example, it is not necessary to provide the peripheral wall 14 of the lever accommodating portion 12 (for example, a structure in which the bottom wall 13 of the lever accommodating portion 12 is supported by a plurality of support pillars positioned in the circumferential direction may be used). In this case, the rigidity of the lid 10 is lowered. However, according to the structure of the present invention, the peripheral wall 14 of the lever accommodating portion 12 is formed in the direction along the lever axis O of the operating lever 50. Can be secured.

Since the operation lever 50 is formed in a disc shape and the lever housing portion 12 is formed in a circular recess shape recessed on the back side of the lid 10, the structure of the operation lever 50 and the lever housing portion 12 can be simplified. it can.
The first engaging portion 51 protrudes from the peripheral portion of the operation lever 50 toward the bottom wall 13 of the lever accommodating portion 12, and the remaining second engaging portion 52 and third engaging portion 53 are the operating lever 50. The first engaging portion 51 to the third engaging portion 53 all extend from the peripheral portion of the operating lever 50 to the peripheral wall 14 of the lever accommodating portion 12. Compared to the structure that protrudes to the side, the height dimension of the operation lever 50 (the length of the operation lever 50 in the lever axial direction) can be set shorter, and the operation lever 50 can be downsized.
The first engaging groove 16 is formed in the bottom wall 13 of the lever housing portion 12, and the remaining second engaging groove 17 and the third engaging groove 18 are formed in the peripheral wall 14 of the lever housing portion 12. Therefore, compared with the structure in which all of the first engagement groove 16 to the third engagement groove 18 are formed in the peripheral wall 14 of the lever accommodating portion 12 of the lid 10, the height dimension of the peripheral wall 14 (operation lever 50 The length of the peripheral wall 14 in the lever axis direction) can be set short, and the lever accommodating portion 12 can be reduced in size.
The remaining second engaging portion 52 and third engaging portion 53 projecting from the peripheral portion of the operation lever 50 toward the peripheral wall 14 of the lever accommodating portion 12 are formed on the peripheral wall 14 of the lever accommodating portion 12. Further, by inserting and engaging the remaining second engagement groove 17 and third engagement groove 18 separately, it is possible to prevent the operation lever 50 from falling off from the lever accommodating portion 12 in the lever axial direction. it can.
In addition, the first engagement portion 51 that protrudes from the peripheral portion of the operation lever 50 toward the bottom wall 13 of the lever accommodating portion 12 is formed in the first engagement groove formed in the bottom wall 13 of the lever accommodating portion 12. Since it is inserted and engaged with the lever 16, movement of the operation lever 50 in the radial direction relative to the lever housing portion 12 can be prevented, and rattling of the operation lever 50 can be prevented.

  Furthermore, since the engagement protrusion 51A of the first engagement portion 51 of the operation lever 50 abuts and engages with the back surface of the bottom wall 13 of the lever housing portion 12, the operation lever 50 accommodates the lever housing portion 12 in the lever housing. It is possible to prevent the portion 12 from slipping out to the outer side of the design surface of the lid 10.

A first rib R1 that protrudes toward the front side of the operating lever 50 is formed at the protruding end of the first engaging portion 51 of the operating lever 50, and the remaining second engaging portion 52 and third engaging portion are formed. 53, a second rib R2 protruding toward the front side of the operating lever 50 is formed, the first rib R1 abuts against the back surface of the bottom wall 13 of the lever housing portion 12, and each second rib R2 is in the second engagement. Since it abuts on the groove surface of the groove 17 and the groove surface of the third engagement groove 18, the following effects can be obtained.
For example, the first engagement portion 51 of the operation lever 50 is inserted into and engaged with the first engagement groove 16 of the lever housing portion 12 of the lid 10, and the remaining second engagement portion 52 and the third engagement portion 16 are engaged. Compared to a structure in which the engaging portion 53 is inserted and engaged with the remaining second engaging groove 17 and third engaging groove 18 separately, the pressure of the operating lever 50 against the lever housing portion 12 is increased. The play of the operation lever 50 can be suppressed.

  Since the first engaging portion 51 to the third engaging portion 53 are located at equal intervals in the circumferential direction of the operation lever 50, the first engaging portion 51 to the third engaging portion 53 are operated. The lever 50 can be arranged in a well-balanced manner on the peripheral portion. Further, when the operation lever 50 is assembled to the lever accommodating portion 12, the second engagement portion 52 and the third engagement portion 53 are inserted into the second engagement groove 17 and the third engagement groove 18, respectively. After the engagement, means for inserting and engaging the first engaging portion 51 with the first engaging groove 16 can be employed, and the operation lever 50 can be smoothly assembled to the lever housing portion 12.

When the operation lever 50 rotates around the lever axis O of the operation lever 50, the cam pin 55 protruding from the back surface of the operation lever 50 is in the cam groove 39 formed in the second plate portion 32 of the engagement member 30. Is moved to press the engaging member 30, and the engaging member 30 is moved back and forth toward the engaged portion side.
According to said structure, the both sides of the 1st plate part 31 of the engaging member 30 are each supported by a pair of 1st nail | claw parts 20, and the both sides of the 2nd plate part 32 are a pair of 2nd claw parts 21. Since the both side portions of the third plate portion 33 are supported by the pair of third claw portions 22, the engagement member 30 is stably supported by the first claw portion 20 to the third claw portion 22. The engaging member 30 can be reliably retracted toward and away from the engaged portion.
The first claw portion 20 and the second claw portion 21 protrude from the back surface of the lid 10 outside the lever housing portion 12, and the third claw portion 22 protrudes from the back surface of the bottom wall 13 of the lever housing portion 12. The operation lever 50 and the engagement member 30 can be overlapped in the thickness direction of the lid 10 (the front and back direction of the lid 10), and the operation lever 50 and the engagement member 30 can be compactly combined to simplify the structure. can do.
In addition, when the engaging member 30 attempts to move freely from the locked state to the unlocking side (retracts to the opposite side to the joined portion 9), the cam pin 55 of the operating lever 50 hits the cam groove 39 of the engaging member 30. The pin insertion hole 19 is formed and the cam pin 55 is disposed so that the movement is prevented. As a result, the cam pin 55 cannot move freely in the retracting direction of the engaging member 30, and the engaging member 30 can be prevented from being retracted and unlocked even though the operating lever 50 is not operated. .
