Yes.

  A key attachment recess 38 is formed in the center portion on the front side of the operation handle 12. In the key mounting recess 38, a key (not shown) is mounted. A rotator 39 is inserted into a hole provided in the bottom wall of the key attachment recess 38, and the rotator 39 protrudes to the back surface side of the operation handle 12 and is secured and fixed by a C-shaped washer 41. It is rotatably mounted on the bottom wall.

  A portion of the rotating body 39 exposed to the inner surface side of the key attachment recess 38 is formed with a key fitting groove 42 that engages with a key (not shown) and rotates the rotating body 39 by operating the key. . Further, a protrusion 43 is formed at a portion protruding from the bottom wall of the key attachment recess 38 of the rotating body 39 so as to be eccentric from the center of rotation.

  The protrusion 43 has a pin shape and protrudes to the back surface side of the lid 13 through the opening 64 of the lid 13. On the other hand, a recess 50 into which the protrusion 43 is inserted is formed on the back surface side of the one lock arm 14 corresponding to the protrusion 43 protruding to the back surface side of the lid 13. As shown in FIGS. 7 and 8 in particular, the recess 50 includes a first side recess 50a having a short length along the longitudinal direction of the lock arm 14 and a second side recess having a long length along the longitudinal direction. 50b and the shape which connected.

  When the rotary body 39 is rotated through the key fitting groove 42 by a key (not shown) arranged in the key attachment recess 38 described above, the protrusion 43 is positioned in the first side recess 50a as shown in FIG. The state can be alternately switched between the state of b) and the state of FIG. 8B positioned in the second side recess 50b.

  The state shown in FIG. 7B is a state where the key is not locked, and the protrusion 43 is disposed at a position where it abuts on the engagement wall portion 51 of the first side recess 50a. Therefore, when the operation handle 12 is pulled in this state, the operation handle 12 rotates about the support shaft 45, and the protrusion 43 rotates. As a result, the projection 43 pushes the engagement wall 51 and slides the lock arm 14 so as to be pulled in from the side of the lid 13. When the lock arm 14 slides as described above, the other lock arm 15 also slides through the rotation lever 60 so as to be pulled in from the side portion.

When the lid 13 is pushed toward the recess of the vehicle body frame 62, the lock piece 18 is fitted into the fitting recess 63 formed on the inner periphery of the vehicle body frame 62, and the lid 13 is closed. Retained.

  At this time, since the taper portion 18a is formed in the lock piece 18, when the lid 13 is closed, the taper portion 18a abuts against the inner periphery of the vehicle body frame 62 and resists the urging force of the tension spring 21. The pair of lock arms 14, 15 are compressed inwardly, so as to get over the inner periphery of the vehicle body frame 62 and fit into the fitting recess 63. Since the above-described protruding rib 29 and elastic guide blade 30 are provided on the inner periphery of the U-shaped frame body 23 of the slide guide 22 that holds the lock arms 14 and 15, the lock arms 14 and 15 are provided. , 15 can be guided smoothly and without backlash. In addition, since the holder 35 that holds the guide shaft 19 is also pressed against the holding piece 33 by the holding spring piece 34 as described above, a smooth guide is provided without play. As a result, the pair of lock arms 14 and 15 slide smoothly without rattling, and no rattling noise is generated even with vibrations caused by road surface unevenness while the automobile is running.

  FIG. 10 shows a state in which the lock pieces 18 of the pair of lock arms 14 and 15 protrude from both sides of the lid 13 and are fitted in the fitting recesses 63 of the vehicle body frame 62 shown in FIG. At this time, as described above, the engagement protrusion 36 of the lock arm 14 is engaged with the stopper wall 47 of the lock release device 40 to restrict the outward projecting position. When the key is not locked, the projection 43 provided on the operation handle 12 is located in the first side recess 50a of the recess 50 of the lock arm 14 as shown in FIG. The engaging wall portion 51 of the first side recess 50 a is in a position where it substantially contacts the protrusion 43. As a result, the outward projecting position of the lock arm 14 is defined by the stopper wall 47 provided on the base portion 37 of the unlocking device 40, and the projection 43 interlocked with the operation handle 12 in this state has the recess 50. It can be accurately set so as to abut against the engaging wall portion 51.

  That is, the position of restricting the outward projection of the lock arm 14 does not vary due to the dimensional error of the lock arms 14 and 15 or the error of the mounting position. There is no play between the matching wall portion 51. As a result, when the operation handle 12 is pulled, the protrusion 43 is rotated, and the engagement wall 51 can be immediately pushed to retract the lock arm 14 inward (see FIG. 11). When the lock arm 14 is drawn inward, the other lock arm 15 is also drawn inward via the rotary lever 60 described above, and the lock pieces 18 of both the lock arms 14 and 15 are fitted to the body frame 62. The lid 13 can be opened by detaching from the recess 63. As described above, the lock arm 14 is slid immediately by operating the operation handle 12, and no play occurs, so that the operation feeling can be maintained well.

  Further, as shown in FIG. 8, when the projection 43 is rotated together with the rotating body 39 by operating a key (not shown), and the projection 43 is placed in the second-side recess 50 b of the recess 50 of the lock arm 14. Will be described. In this case, since the second side recess 50b is long in the longitudinal direction of the lock arm 14, as described above, even when the operation handle 12 is pulled up, the projection 43 is not formed on the wall of the second side recess 50b. Since it only moves within the second side recess 50b without abutting, the lock arm 14 is not moved. For this reason, the lock arms 14 and 15 are held in a state in which the lock pieces 18 are fitted in the fitting recesses 63 of the vehicle body frame 62, and the lid 13 cannot be opened.

  The effects of the embodiment described above will be briefly described below.

  That is, according to the present invention, the first stopper portion 48 that restricts the amount of protrusion of the lock arm 14 to the side of the lid 13 is provided on the stopper wall 47 provided on the base portion 37 of the lock release device 40 and the lock arm 14. Since the engagement projection 36 is engaged, the stop positions of the lock arms 14 and 15 can be accurately defined without affecting the dimensional errors and assembly errors of the lid 13 and the lock arms 14 and 15. As a result, the operation of the operation handle 12 enables the lock arms 14 and 15 to move smoothly without play, improving the operational feeling and reducing the play caused by the play. it can. Further, when the lock arm 14 is pushed inward of the lid 13 against the urging force of the tension spring 21 between the base 37 of the lock release device 40 and the lock arm 14, the movement amount thereof is regulated. By providing the second stopper portion 53, even if the lock piece 18 of the lock arms 14 and 15 is pushed in with a finger or the like, for example, the push-in maximum position is restricted, and the lock arms 14 and 15 are moved from the slide guide 22 or the like. It can prevent coming off. In addition, a hooking portion 44 for locking one end of the tension spring 21 is provided on the pair of lock arms 14 and 15, and the slide guide 22 mounted on the lock piece 18 side of the hooking portion 44 is attached to the tension spring 21.
