  • a pin 14 has both ends inserted in the pair of insertion holes 113 , thereby being held by the strap-attaching parts 112 .
  • the connecting block 13 which has a groove 131 in its bottom surface, connects the strap 12 to the exterior case 111 by the pin 14 held by the strap-attaching parts 112 being housed in the groove.
  • a cover 15 covers the groove 131 housing the pin 14 .
  • the pin 14 includes a pipe 141 , an elastic body 142 built in the pipe 141 , and a pair of sliders 143 that is built in the pipe 141 on either side of the elastic body 142 and that can be translated in the axial direction of the pipe 141 .
  • the pipe 141 is cylindrically formed. Each end face of the pipe 141 has a first opening 144 .

  • Each slider 143 has an end 146 projecting from the first opening 144 to the outside of the pipe 141 . Both ends 146 of the pin 14 are inserted in the insertion holes 113 of the strap-attaching parts 112 , and thereby the pin 14 is held by the strap-attaching parts 112 .
  • the elastic body 142 is a coil spring. At its ends, the elastic body 142 is in contact with the pair of sliders 143 , and presses the sliders 143 to enable the ends 146 to be translated in the axial direction.
  • Each slider 143 has an operating part 147 projecting from the second opening 145 to the outside of the pipe 141 . Operation to draw the operating parts 147 toward the center in the axial direction of the pin 14 translates the ends 146 toward the center of the pin 14 to shorten the pin 14 , so that the pin 14 is removable from the strap-attaching parts 112 .
  • the groove 131 (see FIG. 2 ) to house the pin 14 is formed in the bottom surface of the connecting block 13 .
  • the groove 131 extends from one end to the other end in the axial direction of the pin 14 so that the pin 14 can be inserted from the side surface of the connecting block 13 .
  • the groove 131 is formed so that its maximum width is equal to or slightly greater than the outer diameter of the pipe 141 of the pin 14 .
  • a narrow part 132 is formed so that the width of the groove 131 at this portion is less than the outer diameter of the pipe 141 . In this way, the pin 14 is housed in the groove 131 without falling off.
  • the operating parts 147 extend outward from the narrow part 132 and are operable from outside. Since the pipe 141 is cylindrically formed, the pin 14 housed in the groove 131 is circumferentially rotatable within the range in which the operating parts 147 do not contact the narrow part 132 .

  • the cover 15 is a flat-shaped member extending in the lengthwise direction of the groove 131 so as to cover the groove 131 from one end to the other end in its lengthwise direction, i.e., the whole length of the groove 131 .
  • the cover 15 leaves positions corresponding to the operating parts 147 open so that the operating parts 147 are operable from outside with the groove 131 covered by the cover 15 .
  • the cover 15 has rectangular openings 151 extending in the sliding direction of the operating parts 147 at positions corresponding to the operating parts 147 , and thereby the positions corresponding to the operating parts 147 are left open, so that the operating parts 147 are operable from outside.
  • the cover 15 covering the groove 131 makes the groove 131 invisible from below, ensuring that outward appearance is not of low quality.
  • the operating parts 147 are formed long enough to project from the openings 151 to the outside of the cover 15 with the groove 131 that houses the pin 14 being covered by the cover 15 . This enables a user to hold portions of the operating part 147 projecting from the cover 15 between his/her thumb and finger to operate them.

  • the tips of the extending parts 152 are blocked by the ends 146 of the pin 14 , and thus both ends of the groove 131 are left open without being covered by the extending parts 152 .
  • the user lets go of the operating parts 147 . Then the pin 14 elongates, and the ends 146 are inserted in the insertion holes 153 . In this way, the cover 15 is held on the connecting block 13 with the groove 131 covered.
  • the connecting block 13 is connected to the strap-attaching parts 112 .
  • the user holds the operating parts 147 to draw them close to each other. In this way, the pin is shortened until the tips of the ends 146 come closer to the inside than the extending parts 152 . With this state kept, the connecting block 13 is disposed between the pair of strap-attaching parts 112 of the exterior case 111 .
  • the connecting block 13 After the connecting block 13 is disposed between the strap-attaching parts 112 , the user lets go of the operating parts 147 . Then the pin 14 elongates, and the ends 146 are inserted in the insertion holes 153 and the insertion holes 113 of the strap-attaching parts 112 . In this way, the pin 14 is held by the strap-attaching parts 112 , and the strap 12 is attached to the exterior case 111 .
