  • the charging gun 12 according to the present embodiment is a charging gun 12 of a type in which the operation unit for operating the attaching / detaching mechanism is not the lever 121 as shown in FIG. Even for the charging gun 12 without the lever 121, the concave gun pocket 17 can be configured in the same manner as in the embodiment shown in FIG.
  • the first restricting portion 171 is formed on the ceiling surface 17A of the concave wall surface
  • the second restricting portion 172 is formed on the floor surface 17C of the concave wall surface
  • the back surface 17B of the concave wall surface is formed.
  • the second restricting portion 172 of the present embodiment is erected on the floor surface 17 ⁇ / b> C of the concave wall surface as shown in FIG. 7, instead of the protrusion 174 that receives the tip of the lever 121, and the lower surface of the charging gun 12. It is comprised from the projection part 174 which contact
  • a high friction coefficient member may be attached to the tip of the protrusion 174, or the protrusion 174 itself may be formed from a high friction coefficient material. Further, an engaging portion that engages with the lower surface of the charging gun 12 may be provided at the tip of the protruding portion 174.
  • the operation will be described.
  • the operator inserts the tip of the charging gun 12 into the gun pocket 17 while holding the handle 122 of the charging gun 12. Since the abutting portion 173 is formed on the back surface 17B of the gun pocket 17, the operator can make an appropriate position in the depth direction of the charging gun 12 when the tip end surface of the charging gun 12 abuts on the abutting portion 173. Can be grasped.
  • the upper surface of the tip of the charging gun 12 abuts on the ceiling surface 17 ⁇ / b> A that is the first restricting portion 171, and the lower surface of the middle of the charging gun 12 is the protrusion portion 174 that is the second restricting portion 172. Abuts the tip.
  • the rotation member 182 of the lock mechanism 18 is rotated to the horizontal position, the hole 183 of the fixing member 181 and the hole 184 of the rotation member 182 are overlapped, and pins 183 and 184 are pinned.
  • the charging gun 12 cannot be removed by inserting the padlock.
  • the operator first removes the pins and padlocks inserted through the holes 183 and 184 of the locking mechanism 18. Thereby, the rotating member 182 automatically hangs so as to be retracted from the opening of the recess 17C1 by its own weight. Next, the operator holds the handle 122 of the charging gun 12 and slightly rotates the handle 122 upward (in the direction opposite to the arrow shown in FIGS. 6 and 7).
  • the locking between the charging gun 12 and the gun pocket 17 is released. That is, the engagement between the top surface of the tip of the charging gun 12 and the ceiling surface 17 ⁇ / b> A as the first restricting portion 171 and the engagement between the bottom surface of the lever 121 of the charging gun 12 and the second restricting portion 172 are released. Thereby, the operator can draw out the charging gun 12 as it is.
  • the charging gun 12 since the two restricting portions 171 and 172 for restricting the upper and lower surfaces of the charging gun 12 are provided in the concave gun pocket 17, these two restricting portions 171 and 172 are caused by the weight of the charging gun 12. Thus, the charging gun 12 can be fixed without dropping off. The charging gun 12 can be attached and detached with a very simple operation.
  • the second restricting portion 172 includes a protruding portion 174 that stands in the vertical direction, and the protruding portion 174 engages with the lever 121 of the charging gun 12. It is also possible to suppress the slippage from the gun pocket 17.
  • the protrusion 174 has a tongue 175 extending at an inclination at the tip thereof, so that when the charging gun 12 rotates and the lever 121 is received by the second restricting portion 172, The lever 121 is smoothly set without being caught by the protrusion 174.
  • the back surface 17 ⁇ / b> B of the gun pocket 17 is provided with a contact portion 173 that faces the front end surface of the charging gun 12. For this reason, when the charging gun 12 is set, the operator can grasp the position of the charging gun 12 in the depth direction by abutting the front end surface of the charging gun 12 against the contact portion 173.
  • the contact portion 173 is formed to be inclined with respect to the vertical direction according to the height of the gun pocket 17, the tip surface of the charging gun 12 comes into contact with the contact portion 173. Thus, the operator can more accurately grasp the position in the depth direction.
  • the lock mechanism 18 is provided below the rotation fulcrum of the charging gun 12 in the vertical direction.
  • the charging gun 12 can be firmly locked even with a small locking mechanism.
  • the lock mechanism 18 since the lock mechanism 18 is installed in the opening of the recess 17C1 that receives the lever 121 of the charging gun 12, the lock mechanism 18 does not protrude from the gun pocket 17 and is smaller.
  • the locking mechanism 18 can be used.
  • the rotating member 182 constituting the lock mechanism 18 hangs so as to retract from the opening of the recess 17C1 due to its own weight when unlocked, so that the charging gun 12 can be pulled out immediately after unlocking. it can.
  • the rotation restricting portion restricts the rotation of the charging gun. For this reason, even if it does not provide a lock mechanism so that most charging guns may be covered, a charging gun can be locked only by providing only below a rotation fulcrum. As a result, the lock mechanism can be reduced in size.
