It has the opening 11 and the end wall 12 which covers the edge part on the opposite side to the opening 11. As shown in FIG. Although the peripheral wall 10 is formed in a cylindrical shape, a bulging peripheral wall 18 is formed by enlarging a part of the peripheral wall along the opening 11 to the outside, and the space portion surrounded by the bulging peripheral wall 18 is formed as described above. A recess 14 is formed by closing the surface on the end wall 12 side with the wall 13. A cylindrical guide column 15 extending from the center of the end wall 12 toward the space 9 is provided on the end wall 12. The outer shape of the cross section of the guide column 15 is substantially a regular hexagon. As shown in FIG. 4, the regular hexagon is formed such that a pair of opposing sides come up and down. Therefore, the guide column 15 has an upper surface portion 16 and a lower surface portion 17. And as shown in FIG. 6, the protrusions 20 and 21 are provided in the outer surface of the edge part of the upper surface part 16 and the lower surface part 17 of the guide support | pillar 15, respectively. These protrusions 20 and 21 are for preventing deviation of the sleeve 5 slidably fitted to the guide column 15 as will be described later. In addition, although the groove | channel 19 is formed in the surrounding wall 10, this is for letting the power cord 24 pass. That is, a groove (not shown) is formed in the housing 2 at the same position as the groove 19, the groove 19 having the same vertical width as the groove 19 and slightly deeper than the groove 19. The power cord 24 extends outside through a hole provided in the deep part of the deep groove. When the power cord 24 is wound around the winding portion 7, the power cord 24 extending outside is wound after being pulled in the direction of the winding portion 7 through the deep groove of the housing 2 and the groove 19 of the peripheral wall 10.

  The sleeve 5 is formed in a cylindrical shape and has an insertion hole 42. The outer shape of the cross section of the sleeve 5 has a substantially regular hexagonal shape, and is formed such that a pair of opposing sides come up and down like the outer shape of the cross section of the guide column 15. Similarly, the cross section of the insertion hole 42 has a regular hexagonal shape in which a pair of opposing sides are vertically located. Similarly to the guide column 15, the sleeve 5 also has an upper surface portion 22 and a lower surface portion 23. By inserting the guide column 15 into the insertion hole 42 of the sleeve 5, the sleeve 5 is attached to the guide column 15 and can slide on the guide column 15. Since the cross section of the insertion hole 42 of the sleeve 5 is substantially a regular hexagon and the outer shape of the cross section of the guide column 15 inscribed therein is also a regular hexagon, the sleeve 5 does not rotate around the axis with respect to the guide column 15. As shown in FIG. 7, protrusions 25 and 26 are provided on the outer surfaces of the end portions of the upper surface portion 22 and the lower surface portion 23 of the sleeve 5 on the plug holding portion 8 side. Further, step portions 27 and 28 are provided on the inner surfaces near the end portions on the end wall 12 side of the upper surface portion 22 and the lower surface portion 23, respectively. When the sleeve 5 slides on the guide column 15, the stepped portions 27 and 28 are engaged with the protrusions 20 and 21 of the guide column 15, so that the sleeve 5 does not deviate from the guide column 15.

  As described above, the movable member 6 includes the winding part 7 and the plug holding part 8. The winding portion 7 is formed in a cylindrical shape, a small diameter flange 29 is provided at the end of the winding portion 7 on the projecting direction side, and a large diameter flange 30 is provided on the end portion on the storage direction side. The reason why the flange on the protruding direction side is a small-diameter flange is that the power cord 24 is not caught by the small-diameter flange 29 when the power cord 24 is pulled out with the plug 37 from the wound state of the power cord 24 shown in FIG. It is for doing so. A step portion 36 is provided over the entire circumference of the small-diameter flange 29, and the inner surface of the end portion 47 of the outer wall 46 of the plug holding portion 8 is fitted into the step portion 36 and welded by ultrasonic waves. The plug holding portion 8 is coupled to the small diameter flange 29. Further, the small-diameter flange 29 is provided with a pair of fitting protrusions 48 and 48, so that when the plug holding part 8 is to be attached to the small-diameter flange 29 upside down, the fitting protrusion 48 is provided. 48 interfere with each other to restrict the mounting, so that they cannot be mounted upside down. As shown in FIG. 1, the plug holding portion 8 is formed with a fitting groove 39 for fitting a flat plug 37 so that the plug blade 38 is sandwiched from both sides with the plug blade 38 facing upward. Finger insertion recesses 49 and 49 are provided on the inner surfaces on both sides of the fitting groove 39, respectively. By inserting, for example, a thumb and an index finger into the finger insertion recesses 49, 49, the fitted plug 37 can be easily pulled out. In order to ensure the fitting of the plug 37, the resin portion of the plug 37 is preferably somewhat elastic. Further, the end faces 40 and 40 of the plug holding portion 8 divided by the fitting groove 39 are flush with each other. The fitting groove 39 has such a depth that the plug 37 does not protrude from the end faces 40 and 40 when the flat plug 37 is held. Therefore, if the movable member 6 is completely stored, the plug 37 does not protrude when the hand mixer is placed with the plug 37 at the bottom, so that the movable member 6 can be placed in a stable state. Narrow flanges 41, 41 are formed along the outer peripheries of the end faces 40, 40, and can be used as finger grips when the housed movable member 6 is pulled out, so that the movable member 6 can be pulled out easily. it can.

The winding portion 7 of the movable member 6 is formed in a cylindrical shape and has an insertion hole 31. The end of the insertion hole 31 on the protruding direction side is closed by the plug holding portion 8. The outer shape of the cross section of the cylindrical winding portion 7 is circular, the cross section of the insertion hole 31 is substantially a regular hexagon, and, like the outer shape of the cross section of the sleeve 5, a pair of opposing sides are formed so as to be up and down. Has been. By forming such an insertion hole 31 in the winding portion 7, the winding portion 7 has an upper surface portion 32 and a lower surface portion 33. As shown in FIG. 8, stepped portions 34 and 35 are provided on the inner surfaces of the upper surface portion 32 and the lower surface portion 33 near the storage side. The sleeve 5 attached to the guide column 15 is slidably inserted into the insertion hole 31. That is, the movable member 6 is connected to the guide column 15 via the sleeve 5. Since the cross section of the insertion hole 31 of the movable member 6 is a regular hexagon and the outer shape of the cross section of the sleeve 5 is a regular hexagon, the movable member 6 does not rotate around the axis with respect to the sleeve 5. When the sleeve 5 and the movable member 6 are pulled out so as to protrude most from the opening 11 of the outer wall member 4, as described above, the stepped portions 27 and 28 of the sleeve 5 are the protruding portions 20 and 28 of the guide column 15. 21. The stepped portions 34 and 35 of the movable member 6 are engaged with the protrusions 25 and 26 of the sleeve 5, so that the movable member 6 does not deviate from the sleeve 5. If the movable member 6 is detachable, when the power cord 24 is wound, the plug 37 is fitted to the plug holding portion 8 of the removed movable member 6, and the power cord 24 is wound and wound while turning the movable member 6. When this is completed, the movable member 6 can be attached again.

As shown in FIG. 2, the power cord storage device 3 in which the sleeve 5 and the movable member 6 are incorporated in the outer wall member 4 is fitted in the housing 2. Moreover, as shown in FIG. 1 or FIG. 2, the outer peripheral edge 43 of the outer wall member 4 is flush with the surface of the housing 2. FIG. 9 is a cross-sectional view showing a state in which the winding portion 7 of the movable member 6 is pulled out so that the power cord can be wound. From this state, the plug holding portion 8 is pushed in the storing direction to the winding portion 7. The state accommodated in the outer wall member 4 is shown in FIG. As is apparent from FIG. 10, the movable member 6 has moved in the storage direction, but the sleeve 5 has not moved. This is because the sliding friction between the sleeve 5 and the movable member 6 is smaller than the sliding friction between the guide column 15 and the sleeve 5, and the plug holding portion 8 is pushed and moved from the state where the movable member 6 is projected most. When the member 6 is stored, only the movable member 6 moves first, and the sleeve 5 does not move halfway through the movement. When the movable member 6 is further moved by further pushing the plug holding portion 8 from here, the sleeve 5 is pushed by the plug holding portion 8 that closes the end of the insertion hole 31 of the movable member 6 on the protruding direction side, and moves toward the storage direction side. Moving. And finally, it will be in the accommodation state of the movable member 6 shown in FIG. As is apparent from this figure, it is possible to use the hand mixer by storing only the movable member 6 in a state where the power cord is fully pulled out. 11 is also a state in which the power cord 24 wound around the winding portion 7 of the movable member 6 is accommodated in the housing 2. When the sliding friction between the sleeve 5 and the movable member 6 is larger than the sliding friction between the guide column 15 and the sleeve 5, the movable member 6 and the sleeve 5 first move together. Even a simple configuration is acceptable. Next, a configuration for preventing the movable member 6 from naturally coming out of the outer wall member 4 when the movable member 6 is completely stored in the outer wall member 4 as shown in FIG. 11 will be described. As shown in FIGS. 4 and 8, a projecting piece 44 is provided on the upper end of the large-diameter flange 30 of the winding portion 7. As shown in FIG. 8, a chevron-shaped small protrusion 50 is provided on the upper surface of the end portion of the protruding piece 44. As shown in FIG. 5, a recess 45 is formed at the upper end of the end wall 12 of the outer wall member 4. A protrusion 51 protrudes above the recess 45. When the movable member 6 is completely stored, as shown in FIG. 11, the projecting piece 44 provided on the large-diameter flange 30 projects beyond the end wall 12 from the concave portion 45 of the outer wall member 4. The small protrusion 50 is locked to the end of the protrusion 51 of the outer wall member 4 to restrict the movable member 6 from coming out of the outer wall member 4. As shown in FIG. 10, when the projecting piece 44 is in the outer wall member 4, the projecting piece 44 is pressed against the peripheral wall 10 of the outer wall member 4 and the projecting piece 44 is bent, but the projecting piece 44. When the small protrusion 50 is exposed, the protruding piece 44 returns to a state where it does not bend, and is locked at that time.

In addition, this invention can take a various aspect based on the structure mentioned above. For example, the electric device is not limited to a hand mixer, and can be applied to many electric devices having a power cord such as a hair dryer or an electric iron. In the present invention, the plug holding portion 8 is provided on the movable member 6 and the plug 37 is fixed, so that the winding state of the power cord 24 wound around the winding portion 7 of the movable member 6 can be reliably maintained. The target power supply cord 24 may not be completely stored in the housing 2 but may be partially stored.

By providing the movable member 6 with the plug holding portion 8 that holds the plug 37 of the power cord 24 wound around the winding portion 7 of the movable member 6, the wound state of the stored power cord 24 is reliably maintained. It can be an electric device that can.
