It has become. For example, R3 is preferably 10 μm or more.

  Here, the surface 41 a of the short-side beam (other beam) 41 is closer to the skin 70 side than the surface 43 a of the longitudinal beam (other beam) 43, and the surface of the longitudinal beam (other beam) 43. The vertical distance between 43a and the surface 41a of the short direction bar (other bars) 41 is set to L1. Further, the surface 41a of the short-side beam (other beam) 41 is substantially flush with the surface 44a of the longitudinal beam (other beam) 44, and the surface 44a of the longitudinal beam (other beam) 44 is The vertical distance L3 with the surface 41a of the short direction crosspiece 41 is almost zero.

  As shown in FIG. 8A, the longitudinal bar (raised bar) 45 is formed in a substantially V-shaped cross section. Specifically, a substantially flat plate portion 45a is formed in the central portion in the short direction, and both ends in the short direction of the flat plate portion 45a are directed from the flat plate portion 45a side to both ends in the short direction. Accordingly, an inclined portion 45b that is inclined so as to be positioned upward is provided. The inclined portion 45b is formed in a tapered shape that becomes narrower as it goes from the flat plate portion 45a side to both ends in the short-side direction, and body hair 71 is provided at the short-side ends 45l and 45q of the inclined portions 45b and 45b. Raised portions 45c and 45p are formed, respectively.

  The raised portions 45c and 45p have a raising action for raising the hair (sleeping hair) 71 having a small angle with the skin surface more efficiently. As described above, in the present embodiment, a plurality of raised portions 45c and 45p are provided on the longitudinal beam (raised bar) 45 so as to extend in one direction of the shaving direction (left to right in FIG. 15: a direction). A portion 45p and a raised portion 45c extending in the other direction of shaving (from right to left in FIG. 15) are provided. That is, the plurality of raised portions 45c and 45p are provided on the longitudinal rail (raised rail) 45 so as to extend in at least two directions.

  Furthermore, in this embodiment, the extending direction (shaving direction X) of each raised portion 45C, 45p intersects the longitudinal direction (left-right direction: the relative movement direction of the inner blade 13 relative to the outer blade 8) Y.

  And the raising part 45p exhibits a raising action mainly when moved in one direction of the shaving direction, and the raising part 45c mainly exhibits a raising action when moved in the other direction of the shaving direction. As described above, in the present embodiment, the plurality of raised portions are provided on the raising bar so as to face different directions, so that the raising bar can exhibit the raising action when moving in at least two directions.

  In the present embodiment, the side surface 43 c of the longitudinal beam (other beam) 43 and the side surface 44 c of the longitudinal beam (other beam) 44 also function as raised portions for raising the body hair 71. However, the side surface 43c and the side surface 44c also have a raising action that raises the body hair 71 with a small angle with the skin surface, but the raised portions 45c and 45p are more efficiently sleeping than the side surface 43c and the side surface 44c. The raised hair 71 can be raised. That is, the raising part 45c, 45p has a higher raising force for raising the sleeping hair 71 than the side face 43c and the side face 44c.

  Thus, in the present embodiment, the longitudinal beam (raised beam) 45 is provided with the raised portion (side surface 43c in this embodiment) and the longitudinal beam (other beam) 44 of the longitudinal beam (other beam) 43. The raised portions 45c and 45p having a larger raising force than the raised portions (side surface 44c in this embodiment) are provided.

  Here, in this embodiment, the raising force of at least any one raising part among several raising parts is varied. That is, the raising force of the raising portion 45c is different from the raising force of the raising portion 45p.

  In this embodiment, the raising force of these two raising parts 45c and 45p is made to differ according to the contact pressure with the skin 70 of the longitudinal direction crosspiece (hair raising crosspiece) 45. FIG.

  Specifically, the raised portion (the raised portion 45c located on the top (upper) side of the raised portions 45c and 45p in the present embodiment) at the portion where the contact pressure with the skin 70 of the longitudinal crosspiece (raised rail) 45 is high. ) Is raised smaller than the raising force of the raised portion (the raised portion 45p located on the lower side of the raised portions 45c and 45p in the present embodiment) at the portion where the contact pressure is low.

  And in this embodiment, the raising force of the raising part 45c and the raising force of the raising part 45p are varied by making the form of the raising part 45c and the raising part 45p different.

  Specifically, as shown in FIG. 8 (a), the vertical distance (the outer blade surface 41a and the raised portion) between the short direction end 45l of the raised portion 45c and the surface (outer blade surface) 41a of the shorter direction bar 41 The shortest distance to 45c) is set to L2. And the vertical distance (shortest distance between the outer blade surface 41a and the raised portion 45p) between the short direction end 45q of the raised portion 45p and the surface (outer blade surface) 41a of the short direction crosspiece 41 is set to L4 shorter than L2. Set. That is, the raised portion 45p and the raised portion 45c are provided on the longitudinal rail (raised rail) 45 so that the raised portion 45p is located closer to the skin 70 than the raised portion 45c. In this way, by raising the raised portion 45p closer to the skin 70 side than the raised portion 45c, the raised force of the raised portion 45p provided at the portion where the contact pressure with the skin 70 is low is the portion where the contact pressure with the skin 70 is high. It becomes larger than the raising force of the raising part 45c provided in the.

  In addition, as shown in FIG. 9, you may make it not only make the distance with the outer blade surface 41a different but also make the shape of the raising part 45c and the raising part 45p different. In FIG. 9, the upper part of the raising part 45p is flattened to sharpen the tip of the raising part 45p, and the raising force is increased. And in FIG. 9, since the front-end | tip of the raising part 45p is sharpened, distance L5 with the outer blade surface 41a is made longer than L4. That is, the raised portion 45p is slightly moved away from the skin 70. Further, the distance between the raised portion 45c and the outer blade surface 41a of the raised portion 45p is the same, and the shapes of the raised portion 45c and the raised portion 45p (for example, the radius of curvature of the raised portion 45c and the raised portion 45p) are made different. You may make it have different raising force.

  Further, the longitudinal bar (raised bar) 45 is defined by an upper flat surface 45d of the flat plate portion 45a, an upper inclined surface 45e of the inclined portion 45c, a bottom surface 45f of the flat plate portion 45a, and a lower inclined surface 45g of the inclined portion 45c. Yes.

  In the present embodiment, the upper flat surface 45d and the upper inclined surface 45e correspond to the skin contact surface 45j that contacts the skin 70, and the lower inclined surface 45g introduces the body hair 71 into the outer blade (inner blade side). This corresponds to the body hair introduction surface 45k.

  Further, as described above, the vertical distance between the short direction end 45l of the raised portion 45c and the surface (outer blade surface) 41a of the short direction crosspiece 41 is set to L2, and the short direction end of the raised portion 45p is set. The vertical distance between 45q and the surface (outer blade surface) 41a of the transverse bar 41 is set to L4.

  The longitudinal beam (other beam) 43, the longitudinal beam (other beam) 44, and the longitudinal beam (raised beam) 45 are offset with a size relationship of L3 <L2 <L4 <L1.

  Further, as shown in FIG. 8 (b), the short-side ends 45l and 45q of the inclined portions 45b and 45b are formed in a semicircular shape with a radius of curvature R2, and the magnitude relationship of R2 <R1 ≦ R3 is satisfied. Is set. R2 is preferably 3 μm, for example. Here, the clearance angle α formed between the reference line 60 in the short direction indicated by the two-dot chain line and the upper inclined surface 45e is the distance between the surface 43a of the longitudinal beam 43 (the other beam) 43 and the reference line 60 in the short direction. The clearance angle (0 °) formed and the clearance angle (0 °) formed by the surface 44a of the longitudinal beam (other beam) 44 and the reference line 60 in the short direction are set. In this way, by setting the relief angle at the part where the contact pressure with the skin 70 is high to be smaller than the relief angle α at the part where the contact pressure with the skin 70 is low, the part where the contact pressure with the skin 70 is high is the skin. The effect (damage) on 70 is suppressed.

  Furthermore, in the present embodiment, the longitudinal end 45m of the longitudinal rail (raised rail) 45 has a substantially linear cross section from the side wall surface 41b of the lateral rail 41 toward the longitudinal direction as shown in FIG. The longitudinal end portion 45m and the longitudinal center portion 45n are connected with a gentle curve through a boundary portion 45o. The radius of curvature of the boundary portion 45o is preferably 10 μm, for example.

  Moreover, in this embodiment, while arrange | positioning the longitudinal direction crosspiece (other crosspieces) 43 in the site | part (top part 9a, 10a, 12a) with a high contact pressure with the skin 70 among the area | regions of the net blades 9,10,12. A longitudinal crosspiece (raised crosspiece) 45 is disposed in a portion (outer portions 9b, 10b, 12b) where the contact pressure is low.

  Furthermore, the surface (skin contact surface) 43a that comes into contact with the skin 70 is shorter than the longitudinal beam (other beam) 43 positioned on the inner blade 13 side with respect to the raised portion 45c of the longitudinal beam (raised beam) 45. It is provided so as to be adjacent to the longitudinal bar (raised bar) 45 in front of the direction (front-rear direction: shaving direction) X.

  Specifically, longitudinal bars (raised bars) 45 are provided at the top side (inner side) ends of the outer parts 9b, 10b, 12b extending on both sides in the short direction X of the top parts 9a, 10a, 12a, respectively. Yes.

  Then, the longitudinal bars (other bars) 43 are adjacent to the longitudinal bars (raised bars) 45 on the outer side in the lateral direction X (lower side in FIG. 14) of the respective longitudinal bars (raised bars) 45. Are provided.

  A longitudinal beam (other beam) 43 is also arranged behind the longitudinal beam (raised beam) 45 in the shaving direction. In other words, longitudinal bars (other bars) 43 are arranged on both sides of the longitudinal bar (raised bar) 45 in the short direction.

  Thus, by providing the longitudinal beam (other beam) 43 so as to be adjacent to the longitudinal beam (raised bar) 45, the space in the shaving direction forward of the raised portion 45c is widened, and the skin 70 is more inner bladed. It is possible to bite into the 13th side. That is, when the electric razor 1 is used, the sleeping hairs 71 can be raised more efficiently by causing the raised portions 45c to bite into the skin 70 (see FIG. 15).

  Further, in the present embodiment, the skin 70 is disposed on the outer side in the short-side direction X (lower side in FIG. 14) of the longitudinal beam (other beam) 43 provided adjacent to each longitudinal beam (raised beam) 45. The surface (skin contact surface) 44a in contact with each other is provided with a longitudinal beam (other beam) 44 positioned on the skin 70 side of the raised portion 45c of the longitudinal beam (raised beam) 45.

  Thus, by providing the longitudinal crosspieces (other crosspieces) 44, it is possible to suppress the raised portions 45c from biting into the skin 70 and to suppress the influence (damage) on the skin 70 ( FIG. 15).

  15 illustrates the net blades (outer blades) 9, 10, and 12 moved in one direction of the shaving direction (from left to right in FIG. 15: direction a), but the other direction of the shaving direction (see FIG. 15). Even when the net blades (outer blades) 9, 10, 12 are moved from the right to the left of FIG. In this case, the front and rear in the shaving direction are interchanged.

  Further, in the present embodiment, the short-side bar 41 also has a surface (skin contact surface) 41 a that is in contact with the skin 70 located on the skin 70 side of the raised portion 45 c of the long-side bar (raised bar) 45. The short-side rail 41 and the longitudinal rail (other rails) 44 more effectively suppress the influence (damage) on the skin 70.

  As described above, in the present embodiment, the raising forces of the raised portions 45c and the raised portions 45p provided on the longitudinal beam (raised beam) 45 are different from each other. That is, the raising force of at least any one raising part among several raising parts is varied. Moreover, the raising force of the raising part 45c in the site | part with a high contact pressure with the skin 70 of the longitudinal direction crosspiece (raising raising bar) 45 is made smaller than the raising force of the raising part 45p in a site | part with a low contact pressure. Therefore, it is possible to improve the introduction performance of the sleeping hairs 71 to the outer blade 8 while suppressing the influence on the skin 70.

  Moreover, in this embodiment, the form of the raising part 45c and the raising part 45p is varied by making at least any one of the distance and the shape to the surface (outer blade surface) 41a of the short direction crosspiece 41 different. . Thus, the raising force of the raising part 45c and the raising part 45p can be easily changed only by changing at least one of the distance and the shape to the surface (outer blade surface) 41a of the short direction bar 41a. it can.

  Further, in the present embodiment, the extending direction (shaving direction X) of the raised portions 45c and the raised portions 45p intersects the longitudinal direction (left and right direction: relative movement direction of the inner blade 13 relative to the outer blade 8) Y. Therefore, when cutting the raised body hair 71, it is possible to suppress the body hair 71 from being pulled by the raised portion 45c or the raised portion 45p, and the raised body hair 71 can be cut smoothly.

  Moreover, according to this embodiment, the longitudinal crosspieces (other crosspieces) 43 are arranged in the regions (the top portions 9a, 10a, 12a) where the contact pressure with the skin 70 is high in the areas of the net blades 9, 10, 12.
