The head portion 1 is formed by accommodating a motor and an inner cutter rotated by the motor in a case 11, and having an outer cutter 12 attached to an opening on the front surface of the case 11. The switches and batteries in the housing 10 and the motor in the case 11 are electrically connected by a flexible electric cord or the like.

Support plates 13 are provided on both sides of the upper end of the housing 10 of the razor body 2 and project upwardly.
A locking protrusion 4 is provided protruding from the center of the upper edge of the support plate 13 formed in a semicircular shape. Furthermore, a recessed step 17 is provided on both sides of the blade head portion 1, and locking recesses 5 are provided at a plurality of locations in the arc-shaped concave cross section of the recessed step 17. Among the plurality of locking recesses 5, some of them are formed as fixing locking recesses 5a so that the opening width thereof is approximately equal to the width dimension of the locking protrusion 4, and some of the other locking recesses are The floating locking recess 5b is formed so that its opening width is larger than the width of the locking protrusion 4 (for example, about 1.5 to 2 times). The locking protrusion 4 and the locking recess 5 can form the locking means 3 according to the present invention, and the locking recess 5a allows the locking means 3a to form a floating locking The recessed portion 5b forms a floating locking means 3b. Then, as shown in FIG. 4, by passing the fulcrum shaft 14 from the support plate 13 to the blade head 1, the blade head 1 can be freely rotated around the fulcrum shaft 14,
The blade head part 1 can be attached to the razor main body 2 so as to be tiltable so as to swing up and down in the front-rear direction. At this time, as shown in FIGS. 1 and 2, the locking protrusion 4 is fitted into one of the plurality of locking recesses 5. Incidentally, an arcuate slit-shaped opening 15 is formed in the support plate 13 along its tip edge so that the tip of the support plate 13 provided with the locking protrusion 4 can be easily deformed elastically. The locking protrusion 4 is configured to move smoothly between the locking recesses 5 when the blade head portion 1 is tilted.

[0009]The blade head part 1 is rotated and tilted in the front-back direction, and the fixing locking recess 5 is opened as shown in FIG. 2(a).
By locking the locking protrusion 4 at the

The tilting angle of the blade can be maintained perpendicular to the longitudinal direction of the blade, and by locking the locking protrusion 4 in the locking recess 5a as shown in FIG. 2(b), the blade head The tilting angle of the section 1 can be maintained such that the outer cutter 12 thereof faces straight outward in the longitudinal direction of the razor body 2. In addition, the blade head part 1 is rotated and tilted in the front and rear directions,
By locking the locking protrusion 4 in the floating locking recess 5b as shown in FIG. 1, the outer blade 12 of the blade head portion 1 is aligned with respect to the longitudinal direction of the razor body 2 as shown in FIG. 3(b). The tilting angle can be maintained so that the camera faces diagonally. At this time, since the locking protrusion 4 and the fixing locking recess 5a are formed to have substantially equal width dimensions, the locking protrusion 4 and the fixing locking recess 5a are formed to have substantially the same width. When the portion 4 is locked, the blade head portion 1 is fixed at a predetermined tilt angle. On the other hand, since the floating locking recess 5b is formed to have a larger width than the locking protrusion 4, the locking protrusion 4 is locked in the floating locking recess 5b as shown in FIG. Then, the blade head portion 1 is moved freely at an angle within a range in which the locking protrusion 4 can slide within the floating locking recess 5b, and the blade head portion 1 can freely tilt within this range of angles. Therefore, in areas where the face has a complex curved surface, such as under the chin, the blade head 1 can be tilted freely so that the outer cutter 12 always matches the curved surface of the skin, allowing smooth shaving. It is.
