Abstract:
1. A portable device comprising: a device outer housing forming an exterior of the portable device; a holder fixed to the device outer housing, the holder comprising a generally tubular holding portion extending outside of the device outer housing and a pipe portion integrally connected to the holding portion and extending inside of the device outer housing, wherein the holding portion comprises a first tubular wall and a second tubular wall extending in a coaxial manner from the first tubular wall outside of the device outer housing, and an outer periphery of the first tubular wall is radially larger than an outer periphery of the second tubular wall, so that in which a bearing surface is formed which continues between the outer peripheries of the first and second tubular walls: a generally tubular operation member made of a soft material having waterproof performance and including a packing portion and a push-in portion integrally connected to the packing portion, the push-in portion being positioned around the second wall of the holding portion so that the packing portion of the operation member is seated on the bearing surface of the holding portion; a push shaft positioned inside the holder in such a manner that the push shaft is slidably received in a through-hole of the pipe portion of the holder, the push shaft being operably connected to the push-in portion of the operation member so as to be slidably movable in the pipe portion by pushing operation of the push-in portion of the operation member; and a holding ring including a generally cylindrical portion having an opening through which the push-in portion of the operation member extends out of the holding ring for the pushing operation, the holding ring further including an annular presser portion radially inwardly projecting from the cylindrical portion inside the cylindrical portion, the cylindrical portion being secured around the first and second walls of the holding portion so that the presser portion of the holder ring presses the packing portion of the operation member against the bearing surface of the holding portion inside the holding ring and secures the operation member to the holding portion of the holder.
