  • the hole 54b for mounting and dismounting of the battery 58 is present, so that water easily enters into the storage portion 54e through the hole 54b in the course of transportation of the intermediate product S2, or the like.
  • the interposed structure of the flange portion 57e puts the storage portion 51c in a closed state to make a waterproof construction of the intermediate product S2 but moisture enters into the storage portion 51c and into the storage portion 54e through the hole 54b of the casing 54 in a state, in which the flange portion 57e is inadequately interposed.
  • a waterproof construction of conventional, keyless-entry portable machines involves a problem that moisture is liable to enter into the storage portion 54e through the hole 54b of the casing 54 in the course of transportation of the intermediate product S2, or the like.
  • the invention provides a configuration comprising a lower casing having a bottom wall, a plug loosely fitted into a through hole provided in the bottom wall, a box-shaped keytop formed from a rubber material, a battery, switches and a circuit board received in the keytop, and an upper casing to interpose the keytop between it and the lower casing, the keytop comprising an upper plate portion, an annular side plate portion extending downward from an outer periphery of the upper plate portion, and a cavity surrounded by the upper plate portion and the side plate portion, and wherein when the upper casing and the lower casing are joined together, the upper plate portion is pressed by the upper casing whereby a lower end of the side plate portion is brought into pressure contact with the lower casing and interposed between the upper casing and the lower casing, and an air within the cavity can be discharged from the through hole and when an intermediate product with the upper casing and the lower casing joined is received in a cover, the cover brings the plug into pressure
  • the through hole can also serve for measurement, and a construction is obtained, which is simple and in which measurement is easy.
  • the upper casing and the lower casing are easy to join together, and an operation of holding the keytop and pressing against the bottom wall becomes easy for favorable productivity.
  • the through hole is surely closed by the plug, and when the lower casing and the keytop are again joined at the time of exchange of a battery, an air within the cavity is discharged when the keytop is pushed by the upper casing, so that the lower end of the side plate portion is adequately brought into pressure contact with the bottom wall to make closeness between the keytop and the bottom wall favorable.
  • the invention provides a configuration, in which the plug comprises a plate-shaped flange, a neck projecting from the flange, and a spherical-shaped head provided at a tip end of the neck, and the head is latched to the through hole with the flange positioned outside the lower casing.
  • the plug can be formed in a simple structure and mounting of the plug into the through hole becomes easy.
  • the plug can be mounted in a compact manner, and the flange can also close the through hole to make closeness of the through hole further sure.
  • the invention provides a configuration, in which the cover comprises an upper cover and a lower cover and the upper and lower casings joined are received in the upper and lower covers.
  • the invention provides a configuration, in which the lower cover is provided with a projection to press the plug.
  • Fig. 1 is an exploded, perspective view showing the waterproof construction of the keyless-entry portable machine according to the invention
  • Fig. 2 being a cross sectional view showing an essential part of an outline of the waterproof construction of the keyless-entry portable machine according to the invention

  • Fig. 4 being an enlarged, cross sectional view showing an essential part of the waterproof construction of the keyless-entry portable machine according to the invention.
  • a key 2 Embedded in and mounted to the lower cover 1 is a key 2, with which a door of an automobile is manually locked or unlocked.
  • An upper casing 5 formed from a molding of synthetic resin comprises an upper wall 5a, a plurality of holes 5b formed on the upper wall 5a, an annular side wall 5c extending downward from an outer periphery of the upper wall 5a, a projection 5d for latching provided on an outer periphery of the side wall 5c, and a storage portion 5e surrounded by the upper wall 5a and the side wall 5c.
  • the upper casing 5 and the lower casing 4 are caused to face each other and the side wall 5c is positioned in the side wall 4b of the lower casing 4 to be pushed thereinto, then the projection 5d fits into the recess 4d in a snapping manner to cause the lower and upper casings 4, 5 to be joined in a snapping manner and combined together.
  • a circuit board 6 formed from a printed board and formed thereon with a conductive pattern mounts thereon electric parts such as two push type switches 7, an IC part 8, or the like, to form thereon a transmitting circuit or a transmitting and receiving circuit, the circuit board 6 being disposed in the storage portion 4c while being placed on the partition 4e.
  • a negative terminal plate 9 is formed from a conductive metallic plate having a spring quality, the terminal plate 9 being placed on the bottom wall 4a in a state of being guided by the partition 4e, and connected to the conductive pattern on the circuit board 6.
  • a button type battery 11 is arranged in a state of being connected to the terminal plates 9, 10, respectively.
  • a box-shaped keytop 13 formed from a rubber material comprises a flat-plate shaped upper plate portion 13a, two pressing portions 13b provided to project upward from the upper plate portion 13a, an annular side plate portion 13c extending downward from an outer periphery of the upper plate portion 13a, a cavity 13d surrounded by the side plate portion 13c and the upper plate portion 13a, and a bias portion 13e projecting toward the cavity 13d from the upper plate portion 13a.
  • the upper casing 5 is laid on an upper portion of the keytop 13 to be joined to the lower casing 4 in a snapping manner.
  • the side plate portion 13c bends and the entire periphery of the tip end of the side plate portion 13c is brought into pressure contact with the bottom wall 4a to assure closeness between the keytop 13 and the bottom wall 4a, in which state the keytop 13 is brought into pressure contact and interposed between the lower casing 4 and the upper casing 5.
  • a plug 14 formed from a rubber material comprises a disk-shaped flange 14a, a neck 14b projecting upward from a center of the flange 14a, and a spherical-shaped head 14c provided at a tip end of the neck 14b.
  • the plug 14 is latched with the head 14c loosely fitted into the through hole 4f, and the flange 14a is received and mounted in the recess 4h of the lower casing 4.
  • the electric performance of the intermediate product S1 is checked prior to mounting of the plug 14, such checking of the performance being performed by inserting a measurement probe (not shown) through the through hole 4f and bringing the measurement probe into contact with the conductive unit 12.
  • the intermediate product S1 to which the plug 14 is mounted is in some cases transported to a site of outside order, or the like for final assembly, at which time entry of water is made hard in the course of transportation of the intermediate product S1.
  • Such intermediate product S1 is received in the storage portions 1c, 3d in the lower cover 1 and the upper cover 3, which constitute a cover, to complete a keyless-entry portable machine.
  • the pressing portions 13b of the keytop 13 are put in a state to project through the holes 3b of the upper cover 3, and the projection 1d of the lower cover 1 pushes the plug 14 against the bottom wall 4a to intensely bring the plug 14 into pressure contact with the through hole 4f.
  • the battery 11 is exchanged in a state, in which the lower and upper covers 1, 3, the lower and upper casings 4, 5, and the keytop 13 are disassembled and the plug 14 is removed.
  • exchange of the battery 11 may be performed in a state, in which the plug 14 is latched to the through hole 4f.
