Document Type and Number:
Japanese Patent JP3256478
Kind Code:

Abstract:

PROBLEM TO BE SOLVED: To provide structure having a waterproof function without opening a through hole in a case of a portable telephone set and using an O-ring.
SOLUTION: A knob sliding recess 15 is formed at the front part 11a of a battery housing part of a portable telephone set 1. A sliding knob 13 is housed in the knob sliding recess 15 so as to be capable of sliding. A sliding groove 13b and a spring insertion pin 13c are formed on the back side of the sliding knob 13. When the sliding knob 13 is housed in the knob sliding recess 15, a spring 14 is inserted into the spring insertion pin 13c, the sliding knob 13 is pushed along a sliding guide groove 15a of the knob sliding recess 15, a projection 15b is brought into contact with the rear end of the sliding knob 13, and by furthermore pushing, the projection 15b enters the sliding groove 13b of the sliding knob 13. Although the sliding knob 13 is pushed out outside by the returning force of the spring 14, the projection 15b comes in contact with the wall of the sliding groove 13b of the sliding knob 13, and the pushing out of the sliding knob 13 is stopped.
