本実施形態では、内刃３１ａ〜３１ｄは、外刃ブロック１３ａ〜１３ｄにそれぞれ保持されている。つまり、内刃３１ａ〜３１ｄはそれぞれ外刃ブロック１３ａ〜１３ｄと一体となるように構成されている。そして、各内刃３１ａ〜３１ｄは、各外刃ブロック１３ａ〜１３ｄが各ブロック装着部１４ａ〜１４ｄに装着されることで、モータ１５と駆動連結され、モータ１５の駆動力が各内刃３１ａ〜３１ｄに伝達可能となる。   In the present embodiment, the inner blades 31a to 31d are held by the outer blade blocks 13a to 13d, respectively. That is, the inner blades 31a to 31d are configured to be integrated with the outer blade blocks 13a to 13d, respectively. And each inner blade 31a-31d is drive-coupled with the motor 15 by each outer blade block 13a-13d being mounted in each block mounting part 14a-14d, and the driving force of the motor 15 is each inner blade 31a-. It becomes possible to transmit to 31d.

モータ１５は、前記胴部に設けられた操作スイッチ（図示略）の操作に基づき駆動され、その駆動力にて各内刃３１ａ〜３１ｄが往復振動される。そして、各外刃２２ａ〜２２ｄ内に導入された髭等の体毛がその外刃２２ａ〜２２ｄと往復振動する内刃３１ａ〜３１ｄとで挟んで切除されるようになっている。   The motor 15 is driven based on an operation of an operation switch (not shown) provided on the body, and the inner blades 31a to 31d are reciprocally oscillated by the driving force. The body hairs such as wrinkles introduced into the outer blades 22a to 22d are cut between the outer blades 22a to 22d and the inner blades 31a to 31d that reciprocally vibrate.

上記したような各外刃ブロック１３ａ〜１３ｄは、図２に示すように、その前後方向幅Ａ１〜Ａ４が互いに等しく設定されるとともに、その左右方向幅Ｂ（ブロック装着部１４ａ〜１４ｄの一対の側壁部１２ａ間に嵌められている部分の幅）も互いに等しく設定されている。また、各ブロック装着部１４ａ〜１４ｄは、その前後方向幅が互いに等しく設定されるとともに、その左右方向幅も互いに等しく設定されている。   As shown in FIG. 2, the front and rear direction widths A1 to A4 of the outer cutter blocks 13a to 13d as described above are set to be equal to each other and the left and right direction widths B (a pair of block mounting portions 14a to 14d). The widths of the portions fitted between the side wall portions 12a are also set equal to each other. The block mounting portions 14a to 14d have the same width in the front-rear direction and the width in the left-right direction.

各外刃ブロック１３ａ〜１３ｄにおいて、その支持体２１ａ〜２１ｄの長手方向両端部の側壁４１にはそれぞれ、矩形状の開口４１ａの下端から上方に延びる係合爪４２が形成されている（図３（ａ）（ｂ）参照）。尚、各外刃ブロック１３ａ〜１３ｄの各係合爪４２は全て同一形状であり、そのため、図３及び図４では外刃ブロック１３ａを例にとって図示している。各係合爪４２の上端には、長手方向外側に突出する爪部４２ａが形成され、その爪部４２ａの先端には傾斜部４２ｂが形成されている（図４（ａ）参照）。   In each of the outer blade blocks 13a to 13d, engagement claws 42 extending upward from the lower end of the rectangular opening 41a are formed on the side walls 41 at both ends in the longitudinal direction of the supports 21a to 21d (FIG. 3). (See (a) and (b)). In addition, all the engaging claws 42 of each outer blade block 13a-13d are the same shape, Therefore, in FIG.3 and FIG.4, the outer blade block 13a is illustrated as an example. A claw portion 42a protruding outward in the longitudinal direction is formed at the upper end of each engagement claw 42, and an inclined portion 42b is formed at the tip of the claw portion 42a (see FIG. 4A).

一方、各ブロック装着部１４ａ〜１４ｄを構成する一対の側壁部１２ａにはそれぞれ、係合爪４２の爪部４２ａを上方から挿入可能な係合溝５１が形成されている。尚、係合溝５１は、各ブロック装着部１４ａ〜１４ｄに２つ形成され、全部で８つ形成されている。各係合溝５１は、図４（ａ）に示すように、係合溝５１の爪部４２ａが挿入される挿入口５１ａを側壁部１２ａの上端部に有している。各係合溝５１は、挿入口５１ａから下方に延びるとともに、各係合溝５１の上下方向中間部には、爪部４２ａの上面と上下方向に当接する当接部５２が形成されている。尚、各係合溝５１の当接部５２は、互いに全て同一形状となっている。   On the other hand, an engagement groove 51 into which the claw portion 42a of the engagement claw 42 can be inserted from above is formed in each of the pair of side wall portions 12a constituting each of the block mounting portions 14a to 14d. Two engaging grooves 51 are formed in each of the block mounting portions 14a to 14d, and eight engaging grooves 51 are formed in total. As shown in FIG. 4A, each engagement groove 51 has an insertion port 51a into which the claw portion 42a of the engagement groove 51 is inserted at the upper end portion of the side wall portion 12a. Each engagement groove 51 extends downward from the insertion port 51a, and an abutment portion 52 that abuts the upper surface of the claw portion 42a in the vertical direction is formed in the middle portion of each engagement groove 51 in the vertical direction. In addition, all the contact parts 52 of each engaging groove 51 have the same shape.

各外刃ブロック１３ａ〜１３ｄは、図示しないスプリング等の付勢手段により上方に付勢されており、その付勢力にて各係合爪４２の爪部４２ａは、係合溝５１の当接部５２に対して弾性的に当接するようになっている。これにより、各外刃ブロック１３ａ〜１３ｄは、上方からの負荷がかかっていない状態では、爪部４２ａが当接部５２に当接する位置で保持され、上方から負荷がかかると下方に移動（フロート）する。つまり、各外刃ブロック１３ａ〜１３ｄは、一対の側壁部１２ａ間においてフロート可能に保持されるようになっている。   The outer blade blocks 13a to 13d are urged upward by urging means such as a spring (not shown), and the claw portions 42a of the engagement claws 42 are brought into contact with the engagement grooves 51 by the urging force. 52 is elastically abutted against 52. As a result, the outer blade blocks 13a to 13d are held at a position where the claw portion 42a abuts against the abutting portion 52 when no load is applied from above, and move downward when a load is applied from above (float). ) That is, the outer blade blocks 13a to 13d are held so as to be floatable between the pair of side wall portions 12a.

係合溝５１は、当接部５２と上下方向に対向する下端部５３を有している。係合溝５１の下端部５３は、当接部５２よりも内側（外刃ブロック１３ａ側）まで延びており、外刃ブロック１３ａ〜１３ｄが下方に押圧された状態において、爪部４２ａの下面と係合溝５１の下端部５３とが当接可能となっている。係合溝５１の当接部５２及び下端部５３は、それぞれ上方向及び下方向への係合爪４２の抜け止めの役割を果たしている。つまり、各外刃ブロック１３ａ〜１３ｄは、当接部５２と下端部５３との間隔だけ上下方向の移動が許容されている。   The engagement groove 51 has a lower end portion 53 that faces the contact portion 52 in the vertical direction. The lower end portion 53 of the engagement groove 51 extends to the inner side (outer blade block 13a side) than the contact portion 52, and in a state where the outer blade blocks 13a to 13d are pressed downward, The lower end portion 53 of the engaging groove 51 can come into contact with the engaging groove 51. The contact portion 52 and the lower end portion 53 of the engagement groove 51 serve to prevent the engagement claw 42 from coming off in the upward direction and the downward direction, respectively. That is, the outer blade blocks 13 a to 13 d are allowed to move in the vertical direction by the distance between the contact portion 52 and the lower end portion 53.

各係合溝５１には、側壁部１２ａを左右方向に貫通する窓部５４が、当接部５２と上下方向の位置が重なるように形成されている。図４（ｄ）に示すように、窓部５４から挿入した治具６０で係合爪４２の爪部４２ａを内側に押し込むことで、爪部４２ａと当接部５２との上下方向の係合状態を解除することが可能となっており、これにより各外刃ブロック１３ａ〜１３ｄがブロック装着部１４ａ〜１４ｄから取り外し可能となる。   Each engagement groove 51 is formed with a window portion 54 penetrating the side wall portion 12a in the left-right direction so that the contact portion 52 and the vertical position overlap each other. As shown in FIG. 4 (d), the claw portion 42a of the engagement claw 42 is pushed inward by the jig 60 inserted from the window portion 54, whereby the claw portion 42a and the contact portion 52 are vertically engaged. It is possible to release the state, whereby the outer blade blocks 13a to 13d can be detached from the block mounting portions 14a to 14d.

外刃ブロック１３ａを例えばブロック装着部１４ａに装着する際には、まず図４（ｂ）に示すように、外刃ブロック１３ａをブロック装着部１４ａに対し、付勢手段の付勢力に抗して上方から挿入する。すると、係合爪４２の爪部４２ａの傾斜部４２ｂが係合溝５１に当接して係合爪４２が内側に撓み（図４（ｃ）参照）、そのままの状態で外刃ブロック１３ａを更に下方に挿入すると、係合爪４２が弾性復帰し、爪部４２ａの上面が当接部５２と当接する（図４（ａ）参照）。こうして外刃ブロック１３ａのブロック装着部１４ａへの装着が完了する。   When the outer blade block 13a is mounted on the block mounting portion 14a, for example, first, as shown in FIG. 4B, the outer blade block 13a is opposed to the block mounting portion 14a against the biasing force of the biasing means. Insert from above. Then, the inclined portion 42b of the claw portion 42a of the engagement claw 42 abuts on the engagement groove 51, and the engagement claw 42 bends inward (see FIG. 4C), and the outer blade block 13a is further moved as it is.
