  The slit inner blade 100 is accommodated in the depth inward direction ZB1 of the slit outer blade 40. The plurality of inner blade pieces 102 are located at the same place in the width direction ZA and the depth direction ZB with the plurality of outer blade pieces 41. The plurality of inner blade pieces 102 are located in the proximal direction ZC2 than the plurality of outer blade pieces 41. With this configuration, the distal end direction ZC1 coincides with the direction from the inner blade piece 102 side toward the outer blade piece 41 side. The proximal direction ZC2 coincides with the direction from the outer blade piece 41 side toward the inner blade piece 102 side.

  The slit blade block 30 has a configuration in which an inner blade joint 110 and an outer blade joint 90 are connected to each other by a coil spring 31. The end portion of the coil spring 31 in the distal direction ZC1 is attached to the spring attachment portion 115 of the inner blade joint 110. The end portion of the coil spring 31 in the proximal direction ZC2 is attached to the spring attachment portion 97 of the outer blade joint 90. The coil spring 31 is maintained in a compressed state by the inner blade joint 110 and the outer blade joint 90.

  As shown in FIG. 6A, the comb component 60 surrounds the slit outer blade 40. The comb 72 is adjacent to the outer blade piece 41 of the slit outer blade 40 in the depth direction ZB. The arrangement pitch of the combs 72 is equal to the arrangement pitch of the outer blade pieces 41. The position of the comb 72 in the width direction ZA is the same as the position in the width direction ZA in the depth direction ZB portion of the outer blade piece 41. For this reason, the slit hole 73 of the comb component 60 communicates with the slit hole 42 of the slit outer blade 40.

  The comb support wall 70 is opposed to the slit body 50 (see FIG. 2) of the slit outer blade 40 in the depth direction ZB over the entire width direction ZA. The comb support wall 70 is opposed to the surface of the slit main body 50 of the slit outer blade 40 in the depth outward direction ZB2 at the stepped portion 77 through a gap.

  As shown in FIG. 6B, in the plan view of the slit blade block 30, the dimension HA1 of the comb 72 in the width direction ZA is equal to the dimension HB1 of the outer blade piece 41 in the width direction ZA of the depth outer direction ZB2. equal. For this reason, in the plan view of the slit blade block 30, the dimension HA2 in the width direction ZA of the slit hole 73 of the comb component 60 is equal to the dimension HB2 in the width direction ZA of the slit hole 42 in the outer depth direction ZB2 of the slit outer blade 40. Is equal to

  Further, in the plan view of the slit blade block 30, the dimension HB3 in the width direction ZA of the center portion in the depth direction ZB of the outer blade piece 41 is larger than the dimension HA1 in the width direction ZA of the comb 72. For this reason, in the plan view of the slit blade block 30, the dimension HB4 in the width direction ZA of the slit hole 42 in the center portion in the depth direction ZB of the slit outer blade 40 is smaller than the dimension HA2 in the width direction ZA of the slit hole 73.

  As shown in FIG. 7A, the slit outer blade 40 is placed on the end face in the distal direction ZC <b> 1 of the protrusion 83 of the comb end wall 80 in the connecting portion 43. The comb component 60 is in contact with the surface in the distal direction ZC1 of the mounting portion 92 of the outer blade joint 90 at the end surface in the proximal direction ZC2 of the end wall body 81 of the comb end wall 80. The comb component 60 is in contact with the surface of the mounting portion 92 in the distal direction ZC1 at the end surface in the proximal direction ZC2 of the protrusion 83 of the comb end wall 80. At this time, the accommodation hole 94 accommodates a cut portion from the gate when the mold formed on the end surface in the proximal direction ZC2 of the protrusion 83 is released.

  The end surface in the width direction ZA of the connecting portion 43 of the slit outer blade 40 is opposed to the inner surface in the width direction ZA of the comb end wall 80 of the comb component 60 with a small gap in the width direction ZA. The comb component 60 accommodates the protruding portion 93 of the outer blade joint 90 in the accommodating portion 82.

  Thus, the comb component 60 is sandwiched in the height direction ZC and the width direction ZA by the slit outer blade 40 and the outer blade joint 90 at the protrusion 83. For this reason, the comb component 60 is restricted from moving in the height direction ZC and the width direction ZA with respect to the slit outer blade 40 and the outer blade joint 90.

  As shown in FIG. 7B, the slit outer blade 40 is inserted into the through hole 74 </ b> A of the first housing portion 74 in the first claw piece 51. As shown in FIG. 7C, the slit outer blade 40 is inserted into the through hole 75 </ b> A of the second housing portion 75 in the second claw piece 52.

  As shown in FIG. 7A, the slit outer blade 40 is fitted to the positioning portion 76 in the fitting portion 53. As shown in FIG. 8, in the state where the positioning portion 76 is fitted to the fitting portion 53, the regulating surface 76 </ b> B is a small gap in the height direction ZC from the inner surface forming the through hole 53 </ b> A of the fitting portion 53. Is facing through. In the state where the positioning portion 76 is fitted to the fitting portion 53, the inclined surface 76 </ b> A is accommodated in the fitting portion 53.

The positional relationship between the outer blade piece 41 and the comb 72 will be described with reference to FIG.
The comb 72 is positioned in the distal direction ZC1 more than the end surface (hereinafter referred to as “base end surface 41B”) in the proximal direction ZC2 of the outer blade piece 41 on the end surface in the distal direction ZC1 of the protrusion 72B (hereinafter referred to as “front end surface 72C”). doing. The comb 72 is located in the proximal direction ZC2 in the distal end surface 72C from the end surface in the distal direction ZC1 of the outer blade piece 41 (hereinafter referred to as “the distal end surface 41A”).

  The comb 72 is located slightly in the base end direction ZC2 than the base end surface 41B of the outer blade piece 41 at the end portion in the depth direction ZB2 of the protrusion 72B (hereinafter, “top portion 72D”). The dimension in the height direction ZC (hereinafter referred to as “height dimension L1”) of the distal end surface 72C of the comb 72 and the top portion 72D of the protrusion 72B is the same as the height direction ZC of the distal end surface 41A of the outer blade piece 41 and the proximal end surface 41B. It is smaller than the dimension (hereinafter referred to as “thickness dimension L2”).

The operation of the comb 72 will be described with reference to FIG.
As shown in FIG. 9A, the comb 72 is inserted between the long eyelid BL and the skin SK in a state where the top portion 72 </ b> D has fallen with respect to the skin SK. Thereby, as shown in FIG.9 (b), the long fence BL rides on the top part 72D. As the comb 72 moves, the long blade BL moves along the surface of the comb 72. Thereby, Nagatoro BL is started up. Then, as shown in FIG. 9C, the long wall BL is introduced into the slit hole 73 in a raised state.

With reference to FIG. 7, FIG. 10, and FIG. 11, the operation of the electric shaver 1 will be described.
First, the configuration of the virtual slit blade block 200 will be described with reference to FIG.
The virtual slit blade block 200 includes a slit outer blade 210, a slit inner blade 220, and a comb component 230. The slit outer blade 210 has a plurality of outer blade pieces 211. The slit outer blade 210 has the same shape as the slit outer blade 40. The slit inner blade 220 has a plurality of inner blade pieces 221. The slit inner blade 220 has the same shape as the slit inner blade 100.

  The comb component 230 has a plurality of combs 231. The top portion 232 of the comb 231 is located in the proximal direction ZC2 with respect to the inner blade piece 221 of the slit inner blade 220. In the comb part 230, the height dimension LX1 of the tip end surface 233 and the top part 232 of the comb part 230 in the height direction ZC is larger than the thickness dimension LX2 of the outer blade piece 211 of the slit outer blade 210.

  With such a configuration, when the electric razor is used, the comb 231 comes into contact with the leading end portion of the long scissors BL that has fallen against the user's skin SK. For this reason, the comb 231 starts up only the front end portion of the long wall BL. Thereby, the long rod BL is introduced into the slit outer blade 210 through the slit hole (not shown) of the comb 231 in a state where the root portion falls down from the skin SK. For this reason, the long scissors BL is excised by the outer blade piece 211 and the inner blade piece 221 in a state where the root portion falls from the skin SK. Therefore, the long scissors BL cut by the virtual slit blade block 200 is still long.

  In contrast, in the slit blade block 30 of the present embodiment, the height dimension L1 of the comb 72 is smaller than the height dimension LX1 of the comb component 230 in the virtual slit blade block 200. In the slit blade block 30, the distal end surface 72 </ b> C of the comb 72 is positioned in the distal end direction ZC <b> 1 than the proximal end surface 41 </ b> B of the outer blade piece 41.

  Thereby, as shown in FIG. 10, the top 72 </ b> D of the comb 72 of the comb part 60 is closer to the skin SK than the top 232 of the comb 231. For this reason, the comb 72 contacts the root portion of the long wall BL more than the comb 231. For this reason, the comb 72 starts up the root portion of the long wall BL. Thereby, the long rod BL is introduced into the slit outer blade 40 in a state where the root portion rises through the slit hole 73 (see FIG. 3) of the comb 72. Therefore, the long blade BL is cut off by the outer blade piece 41 and the inner blade piece 102 in a state where the root portion rises. Therefore, the length of the long scissors BL cut by the slit blade block 30 is shorter than the length of the long scissors BL cut by the virtual slit blade block 200. And since the elongate BL cut | disconnected by the slit blade block 30 maintains the standing state, it becomes easy to introduce | transduce into the 1st net blade 22 (refer FIG. 1).

  The thickness L2 of the outer blade piece 41 is set to a size sufficient to prevent the skin SK from entering between the outer blade piece 41 and the inner blade piece 102 when the electric razor 1 is used. Yes. For this reason, when the electric shaver 1 is used, the skin SK is not positioned closer to the base end direction ZC2 than the base end face 41B of the outer blade piece 41. For this reason, when it is assumed that the front end surface of the comb is closer to the base end direction ZC2 than the base end surface of the outer blade piece, the comb is separated from the skin SK. It becomes difficult to start up.

  On the other hand, in the slit blade block 30 of the present embodiment, the distal end surface 72C of the comb 72 is located on the distal direction ZC1 side with respect to the proximal end surface 41B of the outer blade piece 41. For this reason, when the electric razor 1 is used, the front end surface 72C of the comb 72 is in contact with the skin SK. Therefore, the comb 72 can start up the long crab BL that has fallen against the skin SK.

  In addition, the distal end surface 72C of the comb 72 is located in the proximal direction ZC2 with respect to the distal end surface 41A of the outer blade piece 41 of the slit outer blade 40. Thereby, at the time of use of the electric shaver 1, it is suppressed that the corner | angular part 72E of the comb 72 used as the front-end | tip part of the depth inward direction ZB1 in the comb 72 contacts skin SK. For this reason, at the time of use of the electric razor 1, the deterioration of the feeling per skin is suppressed.

  Further, as shown in FIG. 7, the dimension in the height direction ZC of the comb part 60 is smaller than the dimension in the height direction ZC of each welding fixing portion 54, 55 of the slit outer blade 40. Accordingly, the rigidity of the comb part 60 is reduced as compared with the comb part having a dimension in the height direction ZC that is larger than the dimension in the height direction ZC of the comb part 60. For this reason, there is a possibility that the deformation amount of the comb support wall 70 is increased when an external force is applied to the comb support wall 70 through the comb 72 when the electric razor 1 is used.

  On the other hand, the electric shaver 1 of this embodiment has the coupling structure of the following comb components 60 and the slit outer blade 40. That is, the first claw piece 51 of the slit outer blade 40 is accommodated in the first accommodation portion 74 of the comb component 60. The second claw piece 52 of the slit outer blade 40 is accommodated in the second accommodating portion 75 of the comb component 60. The fitting portion 53 of the slit outer blade 40 is fitted to the positioning portion 76 of the comb component 60.

  With these coupling configurations, when the comb support wall 70 of the comb component 60 is deformed in the depth outward direction ZB2 by an external force, the first claw piece 51 and the first accommodating portion 74 come into contact with each other. Moreover, the 2nd nail | claw piece 52 and the 2nd accommodating part 75 contact. Thereby, it is suppressed that the comb support wall 70 deform | transforms into the depth outward direction ZB2.

  In addition, the slit blade block 30 has a configuration in which a plurality of first claw pieces 51 are formed apart in the width direction ZA, and a configuration in which a plurality of first accommodating portions 74 are formed apart in the width direction ZA. Have. For this reason, it is suppressed that the comb support wall 70 deform | transforms into the depth outward direction ZB2 over the wide range of the width direction ZA of the comb support wall 70. FIG.

  When the comb support wall 70 of the comb component 60 is deformed in the proximal direction ZC2 by an external force, the restriction surface 76B of the comb support wall 70 contacts the fitting portion 53. Thereby, it is suppressed that the comb support wall 70 deform | transforms into the base end direction ZC2.

  In addition, the slit blade block 30 has a configuration in which a plurality of fitting portions 53 are formed apart in the width direction ZA, and a configuration in which a plurality of positioning portions 76 are formed apart in the width direction ZA. For this reason, it is suppressed that the comb support wall 70 deform | transforms into the base end direction ZC2 over the wide range of the width direction ZA of the comb support wall 70. FIG.

  Thus, since the deformation | transformation to the depth direction ZB2 of the comb support wall 70 is suppressed, it is suppressed that the comb 72 falls in the depth direction ZB2 along with the deformation | transformation of the comb support wall 70. FIG. Thereby, since it is suppressed that the top part 72D of the comb 72 leaves | separates from the skin SK, the comb 72 can stand up the long basket BL from a root part.

  Further, since the deformation of the comb support wall 70 in the proximal direction ZC2 is suppressed, the comb 72 is suppressed from moving in the proximal direction ZC2 due to the deformation of the comb support wall 70. Thereby, the comb 72 of the center part of the width direction ZA is suppressed from leaving | separating from the skin SK by the bending of the comb support wall 70, for example. For this reason, it can suppress that what declines the function which raises the root part of the long wall BL among several combs 72 generate | occur | produces.

The electric razor 1 of this embodiment has the following effects.
(1) The distal end surface 72C of the comb 72 is positioned on the distal end direction ZC1 side with respect to the proximal end surface 41B of the outer blade piece 41 of the slit outer blade 40 and on the proximal end direction ZC2 side with respect to the distal end surface 41A of the outer blade piece 41. ing. The top portion 72 </ b> D of the comb 72 is located closer to the base end direction ZC <b> 2 than the base end surface 41 </ b> B of the outer blade piece 41. The height dimension L1 of the comb 72 is smaller than the thickness dimension L2 of the outer blade piece 41. According to this configuration, compared to the virtual slit blade block 200, the top portion 72D of the comb 72 is close to the skin SK when the electric razor 1 is used. For this reason, it is possible to introduce the long wall BL in a state of being tilted with respect to the skin SK into the slit hole 73 while being raised by the comb 72. Therefore, the electric razor 1 can cut away the long eyelid BL in a state of falling with respect to the skin SK. In addition, it is suppressed that the feeling per skin is deteriorated due to the comb component 60 protruding in the distal direction ZC1 from the slit outer blade 40.

  (2) The comb 72 is disposed at the same position as the outer blade piece 41 in the width direction ZA. The dimension HA1 of the comb 72 in the width direction ZA is equal to the dimension HA2 of the outer blade piece 41 in the width direction ZA. According to this configuration, in the plan view of the slit blade block 30, the dimension HA2 in the width direction ZA of the slit hole 73 of the comb component 60 is equal to the dimension HB2 in the width direction ZA of the slit hole 42 of the slit outer blade 40. For this reason, as compared with the configuration in which the dimension HA2 of the slit hole 73 is assumed to be smaller than the dimension HB2 of the slit hole 42, the long rod BL raised by the comb 72 is easily introduced into the slit hole 73.

  (3) In the comb component 60, the fitting portion 53 of the slit outer blade 40 is fitted in the positioning portion 76. According to this configuration, the comb support wall 70 is restricted from moving in the height direction ZC with respect to the slit outer blade 40. For this reason, the deformation | transformation to the height direction ZC of the comb support wall 70 is suppressed.

  (4) The welding fixing portions 54 and 55 of the slit outer blade 40 and the welding portions 95 and 96 of the outer blade joint 90 protrude from the comb component 60 in the proximal direction ZC2. According to this configuration, the welding operation of the slit outer blade 40 and the outer blade joint 90 is easily performed. Moreover, the confirmation after welding of each welding fixing part 54 and 55 and each welding part 95 and 96 is easily performed visually.

  (5) In the comb component 60, the first claw piece 51 of the slit outer blade 40 is inserted in the first housing portion 74. According to this configuration, the first claw piece 51 comes into contact with the first housing portion 74 when a force that causes the comb support wall 70 to deform in the outward depth direction ZB2 acts on the comb support wall 70. For this reason, the deformation | transformation to the depth outward direction ZB2 of the comb support wall 70 is suppressed.

  (6) In the comb component 60, the second claw piece 52 of the slit outer blade 40 is inserted in the second housing portion 75. According to this configuration, when the force that causes the comb support wall 70 to deform in the depth outward direction ZB <b> 2 acts on the comb support wall 70, the second claw piece 52 comes into contact with the second housing portion 75. For this reason, the deformation | transformation to the depth outward direction ZB2 of the comb support wall 70 is suppressed.

  (7) The welding fixing portion 105 of the slit inner blade 100 and the welding portion 114 of the inner blade joint 110 protrude in the proximal direction ZC2 from the proximal end surface 71A of the support wall main body 71 of the comb component 60. According to this structure, the welding operation | work of the slit inner blade 100 and the inner blade coupling 110 is performed easily. Moreover, the confirmation after welding of the welding fixing part 105 and the welding part 114 is easily performed visually.

  (8) The slit main body 50 of the slit outer blade 40 is opposed to the comb support wall 70 through the gap at the stepped portion 77. According to this configuration, when the slit outer blade 40 is inserted into the comb component 60, when the comb support wall 70 bends in the depth outward direction ZB <b> 2, both end portions of the comb support wall 70 in the width direction ZA due to the stepped portion 77. Is prevented from interfering with the connecting portion 43 of the slit outer blade 40. Therefore, in a state where the slit outer blade 40 is coupled to the comb component 60, the comb support wall 70 is prevented from being bent in the depth direction ZB.
