  As shown in FIG. 5 (a), the entire extending lines of the clamping surfaces 16 and 19 are continuously curved in the vertical direction which is the vertical direction Z, and a plurality of single arc curves having different curvature radii. 3 (a) and 3 (b), a single circular arc curve or a single circular arc curve with different curvature radii is obtained by curving backward in the horizontal direction X, as shown in FIGS. It consists of multiple continuous curves. One assumed horizontal plane that simultaneously passes through both ends 16a, 16b or 19a, 19b in the extending direction of the extending line in the sandwiching surface 16 or 19 is defined as H, and the both ends 16a, When a large number of assumed vertical planes arranged in the left-right direction Y connecting 16b or 19a, 19b to each other are defined as VY, each of the assumed vertical planes VY out of a large number of intersecting portions 20 intersecting the sandwiching surfaces 16 or 19 The maximum height crossing portion 20 (20V) on the sandwiching surface 16 or 19 where the vertical distance LV formed with respect to the assumed horizontal surface H on the vertical surface VY is the largest is the both end portions 16a, 16b or 19a of the sandwiching surface 16 or 19. , 19b, only one is formed on one end 16a or 19a side from the assumed vertical plane VY passing through the center position 16c or 19c, and this maximum height intersection 20 ( The ratio (N1: N2) of the horizontal distance N1 formed by one end 16a, 19a to the horizontal distance N2 formed by the other end 16b, 19b with respect to the assumed vertical plane VY passing through 0V) is (2: 3) And is preferably set to (1: 4) to (4: 5). When both assumed inclined surfaces passing through the maximum height intersecting portion 20 (20V) and both end portions 16a, 16b or 19a, 19b of the clamping surface 16 or 19 at the same time are defined as S, the clamping surface 16 or 19 The entire extended line is set to a convex shape that is located outside a region T formed by both the assumed inclined surfaces S and the assumed horizontal surface H and swells outside the region T. When the angle of inclination formed by the plane F including the tangent to the extending line of the clamping surface 16 or 19 with respect to the assumed horizontal plane H is θ, the maximum value from both ends 16a, 16b or 19a, 19b of the clamping surface 16 or 19 The extending line of the clamping surface 16 or 19 is set so that the inclination angle θ gradually decreases and the vertical distance LV gradually increases as it goes to the height intersection 20 (20V). . The vertical distance MV between the upper and lower intersecting portions 20 where each of the assumed vertical surfaces VY intersects with the upper and lower sandwiching surfaces 16 or 19 is the same over both ends 16a, 16b or 19a, 19b of the upper and lower sandwiching surfaces 16 or 19. Although set to about 7 mm, it is preferably set to 3 to 15 mm.

  Further, as shown in FIGS. 3 (a) and 3 (b), when one assumed vertical surface passing through both end portions 16a, 16b or 19a, 19b of the clamping surface 16 or 19 at the same time is defined as VX, each assumed vertical surface is Of the intersecting portions 20 where VY intersects the sandwiching surface 16 or 19, the horizontal distance LH made to the assumed vertical surface VX is set to about 1.0 mm, but is set to 0.5 to 3.0 mm. Preferably, the maximum width intersection 20 (20H) on the clamping surface 16 or 19 where the horizontal distance LH is maximum is different from the maximum height intersection 20 (20V) at the clamping surface 16 or 19 Is assumed to be an assumed vertical plane VY passing through a central position 16c or 19c between both ends 16a, 16b or 19a, 19b. These clamping surfaces 16 or 19 are a single circular arc curve, and the radius of curvature is set to 5 to 100 mm.

  In the eyelash curler for the right eye shown in FIG. 2B, the shape of the upper clamping surface 16 and the shape of the lower clamping surface 19 are compared with the eyelash curler for left eye described above. Are different in that they are opposite to each other in the left-right direction Y.

  As shown in FIG. 4A from the non-use state where the operation lever 12 is raised and accommodated between the left and right vertical frame portions 4 of the rear side wall member 3 as shown in FIGS. When the operation lever 12 is pushed down as shown in FIGS. 4B and 4C in the use state in which the operation lever 12 is tilted, the pressing lever 13 is rotated upward by the operation lever 12 so that the movable body 8 is compressed. The movable body 8 is lifted against the urging force of the spring 7, and the movable body 8 stops at the holding position Q where the lower holding surface 19 abuts against the upper holding surface 16. At the clamping position Q, the lower clamping surface 19 is pressed against the front and rear surfaces of the pointed edge 15 with the upper clamping surface 16 entering the groove 18a of the lower clamping surface 19, and the elastic body 18 is shown in FIG. As shown in c), while being compressed, the eyelashes sandwiched between the upper and lower sandwiching surfaces 16 and 19 are pushed down by the upper sandwiching surface 16 and bent along the groove 18a of the lower sandwiching surface 19. At that time, the upper and lower clamping surfaces 16 and 19 hold the eyelashes with substantially the same clamping force. 4B and 4C, when the operation lever 12 is released, the movable body 8 is moved downward by the urging force of the compression coil spring 7 and the pressing lever 13 is rotated downward. Return to the use state shown in (a).

On the other hand, the schematic diagram of FIG. 6 shown as another example 1 of the present embodiment differs from the schematic diagram of FIG. 5 in the following points.

  As shown in FIG. 6 (a), the vertical distance MV is set so as to gradually decrease from both ends 16a, 16b, 19a, 19b of the upper and lower clamping surfaces 16, 19 toward the maximum height intersection 20V. Therefore, as shown in FIG. 6 (b), there is a gap G between the upper and lower clamping surfaces 16 and 19 in a state where only the maximum height intersecting portions 20V of the upper and lower clamping surfaces 16 and 19 are in contact with each other. Arise. The gap G gradually increases from the maximum height intersection 20V toward both ends 16a, 16b, 19a, 19b, and is preferably set to 0.1 to 3.0 mm. Thereafter, as shown in FIG. 6 (c), the upper and lower sandwiching surfaces 16, 19 are compressed at both ends 16a, 16b, 19a from the maximum height intersection 20V side while compressing the elastic body 18 so as to eliminate the gap G. Gradually contact 19b. Due to the gap G, in the contact state of FIG. 6C, the maximum clamping force is generated on the maximum height crossing portion 20V side, and the clamping force is reduced toward the both end portions 16a, 16b, 19a, 19b side.

  In another example 2 of the present embodiment shown in FIGS. 7A and 7B, compared to FIGS. 3A and 3B, the maximum width intersecting portion 20H on the clamping surfaces 16 and 19 is the clamping surfaces 16 and 19. It differs in that it is located on the one end portion 16a, 19a side from the assumed vertical plane VY passing through the center positions 16c, 19c between the two end portions 16a, 16b, 19a, 19b.

  -Since the horizontal distance between both ends in the left-right direction Y of the elastic body 18 is set to about 26 mm, the entire eyelashes can be curled with a single clamping with respect to the eyelashes. This horizontal distance is preferably set to 5 to 35 mm. When this horizontal distance is shortened, only a part of the eyelashes is clamped to curl, or the entire or part of the eyelashes are curled by multiple clamping to the eyelashes, or clamped when the eyelashes are clamped multiple times. You can curl with partial changes in force.
