  • the locking plate portion has a protrusion at the end opposite to the butting direction, while the tip plate portion is inclined outward at a predetermined angle in a direction intersecting the butting direction, so that the protrusion can favorably maintain the locking state of the bridge portion locked in the locking groove. Also, since the tip plate portion is inclined outward, the first locking portion and the second locking portion can be easily engaged and disengaged.
  • the inclination angle of the tip plate portion relative to the locking plate portion is set to 5° to 30°, so that the tip plate portion does not protrude too much from the cover, and the angle makes it easy to engage and disengage the cover.
  • protrusions are formed on at least one of the outer and inner surfaces of the tip plate portion, which provide an anti-slip function when gripping the tip plate portion, making it easier to operate.
  • the bridge portion is positioned at a position spaced outward from the outer surface of the cover body, making it easier to insert the tip piece of the first engagement portion into the inside of the bridge portion.
  • a protrusion is provided on the outer surface of the bridge portion, so that when removing the cover, the protrusion can be used to elastically deform the bridge portion in a direction away from the locking groove, facilitating the operation of releasing the lock between the first locking portion and the second locking portion.
  • the distance from the outer surface of the cover body in a direction intersecting the butt direction to the protruding end of the tip piece is less than the distance from the outer surface of the cover body in a direction intersecting the butt direction to the tip of the protrusion, so that the tip plate portion is less likely to interfere with operation of the protrusion.
  • a sound-absorbing material formed from foamed resin is disposed on at least a portion of the inner surface of the cover body, thereby improving the sound insulation effect when covering an object.
  • a sound-absorbing material is also disposed on at least a portion of the outer surface of the cover body, a higher sound insulation effect can be obtained.
