<p>PROBLEM TO BE SOLVED: To provide an arm-fitting type electronic device whose strap length is adjustable. SOLUTION: A slide piece 7 can be slide when fitted in slide grooves 8. The position of the slide piece on the slide grooves is stabilized when latch pins 10 are caught in recesses 15. Since a plurality of the recesses 15 are disposed at a prescribed interval on the slide grooves 8, a pair of recesses in a most suitable position can be chosen and the pair of latch pines 10 are caught on the recesses. Since the slide piece 7 is formed in one piece with the insertion section of the strap, deciding a position of the slide piece results in adjusting a strap length around the arm. Since the latch pin 10 is biased only by a spring and the recesses 15 are not so deep as to be engaged with the latch pins, the slide piece 7 position can also be changed by pushing or pulling the slide piece 7 with strength.</p> |
