Therefore, there is no particular problem even if the engagement relationship is easily released when the bumper 30 moves in the first negative direction X2.
  • the first protrusion 23 easily deforms in response to a force in the direction along the second axis Y, but does not deform in response to a force in the direction along the first axis X. Hateful. Since the first protrusion 23 has the latch surface 23A, deformation of the first protrusion 23 when a force in the direction along the first axis X is applied to the latch surface 23A can be suppressed.
  • the bumper 30 is located on the outer side than the latch 20 when viewed from the direction along the second axis Y. As a result, when the locking mechanism 10 is fixed to the rack 80, the bumper 30 is sandwiched between the latch 20 and the rack 80. That is, when the lock mechanism 10 is fixed to the rack 80, the bumper 30 is supported by the latch 20 and the rack 80 and is difficult to deform.
  • the second protrusion 33 of the bumper 30 comes into contact with the through hole 84 of the rack 80, etc. That is, when removing the exterior body 50 from the rack 80, a load is applied to the bumper 30.
  • the bending rigidity of the bumper 30 is smaller than that of the latch 20. That is, the bumper 30 is more flexible than the latch 20. Therefore, even when a load is applied to the second protrusion 33, the bumper 30 is bent, so that irreversible deformation of the bumper 30, cracking of the bumper 30, etc. can be suppressed.
  • the lock mechanism 10 may include another flat plate in addition to the latch 20 and bumper 30.
  • the lock mechanism 10 may further include a flat plate stacked on the surface of the bumper 30 on the third positive direction Z1 side.
  • the bumper 30 may have a slit passing through the second flat plate 31.
  • the bumper 30 has a slit 38 that penetrates the second flat plate 31 in the third axis Z direction.
  • the slit 38 extends parallel to the first axis X.
  • the slit 38 is located on the first positive direction X1 side when viewed from the second protrusion 33.
  • the slit 38 is located at the center of the second flat plate 31 in the direction along the second axis Y.
  • the bending rigidity of the bumper 30 is lower than when the bumper 30 does not have the slit 38.
  • Such a bumper 30 is more easily bent than the bumper 30 of the above embodiment. Therefore, even when a load is applied to the second protrusion 33, the bumper 30 is bent, thereby suppressing irreversible deformation of the bumper 30 due to the load.
  • the second flat plate 31 of the bumper 30 may partially have a thin portion whose dimension in the direction along the third axis Z is smaller than other portions. Further, such a thin portion is preferably located on the first positive direction X1 side of the second flat plate 31 when viewed from the second protrusion 33. In this case as well, the bending rigidity of the bumper 30 can be reduced in the thin portion.
  • the dimension of the second flat plate 31 of the bumper 30 in the direction along the second axis Y may be constant regardless of the position in the direction along the first axis X.
  • the first flat plate 21 is also the same, and the dimension in the direction along the second axis Y may be constant regardless of the position in the direction along the first axis X.
  • the minimum dimension L1 of the second flat plate 31 in the second axis Y may be larger than the minimum dimension of the first flat plate 21 in the direction along the second axis Y. Further, the minimum dimension L1 of the second flat plate 31 in the second axis Y may be the same as the minimum dimension of the first flat plate 21 in the direction along the second axis Y.
  • the dimension of the first flat plate 21 in the direction along the first axis X may be smaller than or the same as the dimension of the second flat plate 31 in the direction along the first axis X.
  • the end of the bumper 30 on the first negative direction X2 side may protrude from the end of the exterior body 50 on the first negative direction X2 side.
  • the materials of the latch 20 and bumper 30 do not matter.
  • the latch 20 and bumper 30 may be made of synthetic resin.
  • the position of the second protrusion 33 of the bumper 30 in the direction along the first axis X may be different from the example of the above embodiment.
  • the second protrusion 33 may be located between the two first protrusions 23 in the direction along the second axis Y. According to this configuration, even if the first protrusions 23 try to deform in a direction toward each other, the second protrusions 33 restrict the deformation. Therefore, according to this configuration, deformation of the first protrusion 23 can be suppressed.
  • the bumper 30 may be superimposed on the surface of the first flat plate 21 of the latch 20 on the opposite side to the main surface 22. That is, the bumper 30 may be in contact with the latch 20 on the side opposite to the main surface 22 of the first flat plate 21 .
  • the bumper 30 and the latch 20 may be stacked on the exterior body 50 in this order.
  • the second protrusion 33 of the bumper 30 is located on the first negative direction X2 side when viewed from the first protrusion 23 of the latch 20.
  • the bending rigidity of the bumper 30 may be greater than that of the latch 20. Further, the bending rigidity of the bumper 30 may be the same as that of the latch 20. However, the bending rigidity of the bumper 30 is preferably such that the bumper 30 is not irreversibly deformed when released from the rack 80.
  • the first protrusion 23 may protrude from above the main surface 22 of the first flat plate 21.
  • the number of the first protrusions 23 may be one, or three or more.
  • the shape of the first protrusion 23 does not matter as long as it has the latch surface 23A perpendicular to the first axis X.
  • the first protrusion 23 may have a rectangular shape, a square shape, or a triangular shape.
  • the acute angle P formed by the first slope 34A of the second protrusion 33 and the first axis X is not limited to the example of the above embodiment.
  • the acute angle P between the first slope 34A of the second protrusion 33 and the first axis X is preferably 20 degrees or more and 70 degrees or less. Within this angle range, the effect described in (4) above can be easily obtained.
  • the acute angle P between the first slope 34A and the first axis X, and the acute angle Q between the second slope 34C and the first axis X. may be at different angles.
