Therefore, the pulling force applied from the outside to the first lead wire and the second lead wire exerts an influence on each connection portion between the first land and the second land at each end of the first lead wire and the second lead wire. Will be reduced. Therefore, the connecting portions of the first land and the second lead wire to the first land and the second land at the respective ends of the first lead wire and the second lead wire are pulled and the lead wire is broken, and therefore the lead wire is not exposed to external pulling force. It becomes possible to endure.

As shown in FIGS. 2 and 4, the support body 2 and the movable body 3 are provided with a connector 90 having at least one of elasticity and viscoelasticity. In the present embodiment, the connecting body 90 is the viscoelastic member 9 provided at a position where the support body 2 and the movable body 3 face each other in the first direction Z, and the first direction Z, the second direction X, and the third direction. It is elastically deformable in the direction Y. Viscoelasticity is a property that combines both viscosity and elasticity, and is a property remarkably found in polymer substances such as gel-like members, plastics, and rubber. Therefore, various gel-like members can be used as the viscoelastic member 9. Further, as the viscoelastic member 9, natural rubber, diene rubber (for example, styrene/butadiene rubber, isoprene rubber, butadiene rubber), chloroprene rubber, acrylonitrile/butadiene rubber, etc., non-diene rubber (for example, butyl rubber, ethylene/ Various rubber materials such as propylene rubber, ethylene/propylene/diene rubber, urethane rubber, silicone rubber, fluororubber) and thermoplastic elastomers and modified materials thereof may be used.

In this embodiment, the viscoelastic member 9 (the first viscoelastic member 91 and the second viscoelastic member 92) is a silicone gel having a penetration of 10 to 110 degrees. The penetration degree is defined by JIS-K-2207 or JIS-K-2220, and the smaller the value, the harder it is. The viscoelastic member 9 has a linear or non-linear expansion/contraction characteristic depending on the expansion/contraction direction. For example, when the viscoelastic member 9 is pressed in the thickness direction (axial direction) and is compressed and deformed, the viscoelastic member 9 has expansion and contraction characteristics in which the nonlinear component (spring coefficient) is larger than the linear component (spring coefficient). On the other hand, when it is stretched by being pulled in the thickness direction (axial direction), it has expansion/contraction characteristics in which the linear component (spring coefficient) is larger than the nonlinear component (spring coefficient). On the other hand, when the viscoelastic member 9 is deformed in the direction (shear direction) intersecting the thickness direction (axial direction) as in the present embodiment, the deformation is in a direction in which the viscoelastic member 9 is pulled and stretched regardless of the movement. Therefore, it has a deformation characteristic in which the linear component (spring coefficient) is larger than the nonlinear component (spring coefficient). Therefore, in the viscoelastic member 9, the spring force depending on the movement direction is constant. Therefore, as in the present embodiment, by using the spring element of the viscoelastic member 9 in the shearing direction, the reproducibility of the vibration acceleration with respect to the input signal can be improved, so that the vibration with a subtle nuance is realized. be able to.

(basic action)
In the actuator 1 according to the present embodiment, when an alternating current is applied to the coil 7 via the first lead wire and the second lead wire, the movable body 3 vibrates in the second direction X, so that the center of gravity of the actuator 1 moves in the second direction X. Fluctuates. Therefore, the user can feel the vibration in the second direction X. At that time, the AC waveform applied to the coil 7 is adjusted so that the acceleration that the movable body 3 moves to one side X1 in the second direction X and the acceleration that the movable body 3 moves to the other side X2 in the second direction. If they are different, the user can experience the directional vibration in the second direction X.

(Main effects of this embodiment)
As described above, in the actuator 1 of the present embodiment, the end portion of the coil 7 is electrically connected, and the wiring board 15 fixed to the outer surface 110 of the holder 60 as a support body serves as a lead wire connection portion. A first land 151a and a second land 151b are formed. The first land 151a and the second land 151b are formed in the vicinity of the first land 151a and the second land 151b. The first land 151a and the second land 151b are adjacent to the third outer surface 113 to which the wiring board 15 is fixed. On the outer side surface 111, a groove 115 for inserting and holding the first lead wire and the second lead wire electrically connected to the first land 151a and the second land 151b, a lead wire holding portion 116, etc. are formed. ing. Therefore, even if a special part such as a binding band is not used, the ends of the first lead wire and the second lead wire are pulled and the first lead wire and the second lead wire are disconnected. It becomes possible to withstand the first lead wire and the second lead wire against the pulling force.

According to the actuator 1 of the present embodiment, the first lead wire connected to the first land 151a and drawn from the first land 151a and the second lead wire connected to the second land 151b and drawn from the second land 151b are It is inserted into the groove 115 formed on the outer surface of the support body 2 and is held in the groove 115 by the lead wire pressing portion 116. Therefore, even if the movable body 3 moves relative to the support body 2 and causes the support body 2 to vibrate, the lead wire holding portions 116 of the first lead wire and the second lead wire hold the groove 115 in the groove 115. The vibration of the portions causes the stress to concentrate and less likely to be applied to the connecting portions between the first land 151a and the second land 151b at the respective ends of the first lead wire and the second lead wire due to the vibration. .. Therefore, even if the movable body 3 relatively moves with respect to the support body 2 and causes the support body 2 to vibrate, the first land 151a and the second land 151a at each end of the first lead wire and the second lead wire are generated. It becomes difficult for disconnection to occur at each connection portion with 151b, and it becomes possible to withstand the lead wire against pulling force from the outside.

Further, according to the actuator 1 of the present embodiment, the first lead wire and the second lead wire are separately inserted into the first lead wire groove 115a and the second lead wire groove 115b, respectively, and the first lead wire holding portion 116a is formed. And the second lead wire retainer 116b separately holds the first lead wire groove 115a and the second lead wire groove 115b. Therefore, the lead-out portions of the first lead wire and the second lead wire from the support body 2 are held in the first lead wire groove 115a and the second lead wire groove 115b, respectively. The vibrations of the support body 2 concentrate stress on the respective connecting portions of the first land 151a and the second land 151b at the end portions, which makes it difficult to apply the stress. Therefore, disconnection or the like is less likely to occur at each connection portion between the first land 151a and the second land 151b at each end of the first lead wire and the second lead wire, and the lead wire can withstand the tensile force from the outside. It will be possible to get it.

Further, according to the actuator 1 of the present embodiment, when the first lead wire and the second lead wire having different wire diameters are used, the first lead wire and the second lead wire having a large wire diameter and the first outer diameter are , The first lead wire 115a and the second lead wire groove 115b, each of which is inserted into the first width groove 115c having the first width and has a small outer diameter and a second outer diameter. Are respectively inserted into the second width groove 115d having the second width of the first lead wire groove 115a and the second lead wire groove 115b. Then, the first lead wire and the second lead wire, which have a large wire diameter and are inserted into the first width groove 115c, are respectively held in the first width groove 115c by the first pressing portion 116c and inserted into the second width groove 115d. The first lead wire and the second lead wire each having a small wire diameter are held in the second width groove 115d by the second pressing portion 116d. Therefore, even when the first lead wire and the second lead wire having different wire diameters are used, each of the first land 151a and the second land 151b at each end of the first lead wire and the second lead wire is The stress is concentrated on the connection portion due to the vibration of the support body 2 and becomes hard to occur, and the connection between the first land 151a and the second land 151b at each end portion of the first lead wire and the second lead wire is disconnected. Etc. are less likely to occur, and it becomes possible to withstand the lead wire against pulling force from the outside.

Further, according to the actuator 1 of the present embodiment, the first width groove 115c and the second width groove 115d having different groove widths, and the first pressing portion that partially covers the first width groove 115c and the second width groove 115d. By forming 116c and the second holding portion 116d, the inserted first lead wire and second lead wire are less likely to come off.

In addition, according to the actuator 1 of the present embodiment, the first lead wire or the second lead wire having the first outer diameter with the large wire diameter is guided by the slope 116e formed in the second holding portion 116d to have the first width. It is easy to lead to the groove 115c. In addition, the first lead wire or the second lead wire having the second outer diameter with the smaller wire diameter is guided by the slope 116e formed in the second pressing portion 116d, and passes through the first width groove 115c to have the second width. It is easy to lead to the groove 115d. Therefore, the first lead wire and the second lead wire having different wire diameters can be easily inserted into the first width groove 115c and the second width groove 115d, and the mountability of each lead wire is improved.

Further, according to the actuator 1 of the present embodiment, the first lead wire or the second lead wire having the first outer diameter having the large wire diameter is pulled out from the first width groove 115c, and the first lead wire having the second outer diameter having the small wire diameter is drawn. The lead wire or the second lead wire is drawn out from the second width groove 115d. Therefore, the height of the first land 151a and the second land 151b formed on the wiring board 15 in the third direction Y and the height of the first lead wire and the second lead wire drawn from the support body 2 in the third direction Y. Are set to different heights. According to such a configuration, the height of the lead-out portions of the first lead wire and the second lead wire, which are loosened by the tensile force applied to the first lead wire and the second lead wire, is formed on the wiring board 15. It is different from the formation height of the land 151a and the second land 151b. Therefore, due to this difference in height, the movable body 3 moves relative to the support body 2 and the vibration generated in the support body 2 and the swaying movement of the lead-out portions of the first lead wire and the second lead wire cause the first land 151a. And it becomes difficult to be transmitted to the second land 151b. Therefore, the movable body 3 relatively moves with respect to the support body 2 and the vibration generated in the support body 2 or the tensile force applied to the first lead wire and the second lead wire causes the movement of the first lead wire and the second lead wire. The influence of each end on the connection between the first land 151a and the second land 151b is reduced. Therefore, the connection between the first land 151a and the second land 151b at each end of the first lead wire and the second lead wire is less likely to be disconnected due to the vibration of the support 2, and Due to the tensile force applied to the lead wire and the second lead wire, it is more difficult to cut or peel off.

It is a circular air core coil. The coil 7 is held by the coil holding frame 708 and fixed to the holder 60A, and is provided on the support body 2 side.

Two coil holding holes 708a and 708b are formed in the coil holding frame 708 so as to be juxtaposed in the second direction X, and the coil 7 is arranged in each of the coil holding holes 708a and 708b. The coil holding holes 708a and 708b are through holes, and receiving portions 709 and 710 are formed at both ends in the third direction Y at the ends of the coil holding holes 708a and 708b on the other side Z2 in the first direction Z. There is. Therefore, when the coil 7 is mounted in the coil holding holes 708a and 708b from the one side Z1 in the first direction Z, the short side 702 (ineffective portion) of the coil 7 is received by the receiving portions 709 and 710 on the other side Z2 in the first direction Z. It will be in a supported state.

(Structure of holder 60A)
As shown in FIGS. 10 and 12, the holder 60A is plate-shaped, and the coil 7 (coils 71, 72) has a first air-core portion on the surface on the one side Z1 in the first direction Z of the holder 60A. The surface on the other side Z2 in the first direction Z is fixed to the direction Z with an adhesive or the like. The holder 60A is made of a non-magnetic material. The holder 60A is made of a metal plate. In this embodiment, the holder 60A is made of a non-magnetic stainless steel plate. The holder 60A has a thickness of 0.1 mm, for example.

In this embodiment, since the holder 60A is plate-shaped, one side Y1 of the third direction Y is bent in the one side Z1 of the first direction Z to form the first bending portion 603 for reinforcement. There is. More specifically, the end portions on both sides of the holder 60A in the third direction Y have a first reinforcing bent portion 603 that extends in the second direction X while being bent in the other side Z of the first direction Z. I am configuring. Therefore, the holder 60A is unlikely to bend in the first direction Z in the direction along the second direction X.

The holder 60A is formed with a second bent portion 604 as a plate-shaped contact portion bent and raised to the other side Z2 in the first direction Z at positions sandwiching the coil holding frame 708 in the second direction X. The end of the second bent portion 604 on the one side Z1 in the first direction Z is located on the one side Z1 in the first direction Z with respect to the coil 7. A rectangular tape 605 is attached to the side surface of the first bending portion 603 on the one side Y1 in the third direction Y. On the surface of the holder 60A sandwiched between the pair of second bent portions 604, three mounting holes 606 are formed at both ends in the third direction Y along the second direction X. Further, on the surface of the coil holding frame 708 facing the holder 60A, three protrusions 711 are provided at both ends in the third direction Y along the second direction X. The projection 711 of the coil holding frame 708 is inserted into the mounting hole 606 of the holder 60A, and is attached to the holder 60A together with the held coil 7.

A first opening 601 is formed in the holder 60A adjacent to the second bent portion 604 on one side X1 of the second direction X, and adjacent to the second bent portion 604 on the other side X2 of the second direction X. The second opening 602 is formed. The first opening 601 and the second opening 602 penetrate the holder 60A in the first direction Z. That is, since the second bent portion 604 is a portion where the holder 60A is cut and raised, the holder 60A has a mark formed by cutting and raising the two second bent portions 604 as the first opening 601 and the second opening 602. Has been formed. In the present embodiment, the first opening 601 and the second opening 602 are provided at positions sandwiching the region where the two coils 7 are arranged on both sides in the second direction X. The second opening 602 is located near the coil holding frame 708 that holds the coil 7. Therefore, the first opening 601 and the second opening 602 are bent in the one side Z1 in the first direction Z at the edges on the coil holding frame 708 side. The first opening 601 and the second opening 602 are larger in size than the second bending portion 604, and are used for connecting two yokes described later.

Through holes 60f are formed at the four corners of the holder 60A. A pair of through holes 60g is formed near the axis C of the through hole 60f at the other diagonal position of the holder 60A sandwiching the axis C in the second direction X. The through hole 60g has a diameter that allows the pair of protrusions 16g formed on the first cover member 16 to pass therethrough.

(Structure of support 2)
In the present embodiment, the holder 60A is stacked on the first cover member 16 in the first direction Z, and the second cover member 17 is stacked on the holder 60 in the first direction Z, so that the hook portion 17h is elastic. Thus, the projection 16h is passed over the projection 16h, the projection 16h is fitted into the notch 17i of the hook 17h, and the hook 17h is engaged with the projection 16h. As a result, the support 2 is formed.

At this time, due to the elasticity of the hook portion 17h, a force that brings the first cover member 16 and the second cover member 17 closer to each other acts. Therefore, due to this force, each component forming the support body 2 is assembled without rattling. In addition, the cylindrical boss 16g formed on the first cover member 16 penetrates the through hole 60g of the holder 60A, the tip portion projects from the holder 60A, and the periphery of the tip portion is formed on the second cover member 17. It is surrounded by the inner circumference of the hole 17g. When a gap is created between the first cover member 16 and the second cover member 17, an inclination occurs between the periphery of each tip of the pair of cylindrical bosses 16g and the inner circumference of the pair of mounting holes 17g, and The periphery of each tip of the cylindrical boss 16g comes into contact with the inner circumferences of the pair of mounting holes 17g. In this way, at the other diagonal position of the support body 2, the periphery of the tip end portions of the pair of cylindrical bosses 16g abuts the pair of mounting holes 17g, so that the first diagonal position of the support body 2 at the other diagonal position is obtained. The movement between the cover member 16 and the second cover member 17 is suppressed, and the fixing strength between the first cover member 16 and the second cover member 17 is secured.

Further, when the hook portion 17h engages with the protrusion 16h, the convex plate portion 164a of the first cover member 16 fits into the recess 174b of the second cover member 17.

Has been done.

In this embodiment, since the notch 163b is formed in the first cover member 16, when the coil 7 is fixed in the coil holding holes 708a and 708b of the coil holding frame 708, the first end 706 at the beginning of winding and the winding The second end portion 707 at the end is pulled out to the outside through the notch 163b, and then the first cover member 16, the holder 60A and the second cover member 17 are overlapped and connected in the first direction Z. As a result, the first end portion 706 and the second end portion 707 are pulled out from the hole 638.

After the first cover member 16, the holder 60A, and the second cover member 17 are overlapped and connected in the first direction Z, the wiring board 15 can be fixed to the recesses 168 and 178. At that time, the wiring board 15 is positioned by aligning the notch 150 of the wiring board 15 with the notch 163b of the first cover member 16, and then the wiring board 15 is fixed by an adhesive or the like. Therefore, the coil 7 can be driven from the outside via the wiring board 15. Here, since the wiring board 15 is formed with the notch 150 that opens the hole 638, the first end portion 706 and the second end portion 707 pulled out from the hole 638 are passed through the notch 150 and the wiring board Each of the 15 lands 151 is extended and soldered to the lands 151. As a result, the two coils 7 are electrically connected in series. The two coils 7 may be electrically connected in parallel.

The third groove 115C communicates with the second groove 115B that is guided to the one side X1 of the second direction X again. In addition, the lead wire retainer 116 includes a first retainer 116A that partially covers the second groove 115B and a second retainer 116B that covers the third groove 115C.

The first groove 115A is formed so as to extend from the semicircular cutouts 152a and 152b of the wiring board 15 to the other side Y2 in the third direction Y and extend in the second direction X. There is no pressing portion on the side Y1 and it is exposed on the outer surface of the support 2. The second groove 115B forms an integral space adjacent to the first groove 115A that has fallen from the semicircular cutouts 152a and 152b, and is in the first direction between the first pressing portion 116A and the second pressing portion 116B. It is formed by a space extending in Z. In the third groove 115C, one side Y1 in the third direction Y is closed by the second pressing portion 116B, the other side Z2 in the first direction Z is surrounded by the inner wall surface 201 of the support 2, and the third direction 115C in the first direction Z is defined. One side Z1 is formed by a space exposed on the bottom surface which is the outer surface of the support body 2, and forms a space integral with the adjacent second groove 115B.

In the present embodiment, the third groove 115C includes the first width groove 115D having a first width into which the first lead wire and the second lead wire having the first outer diameter are inserted, and the second outer diameter smaller than the first outer diameter.

(Main effects of this embodiment)
As described above, in the actuator 1A of the present embodiment, the end portion of the coil 7 is electrically connected, and the wiring board 15 fixed to the outer surface 110 of the holder 60A as a support body serves as a lead wire connection portion. A first land 151a and a second land 151b are formed. The first land 151a and the second land 151b are formed in the vicinity of the first land 151a and the second land 151b. The first land 151a and the second land 151b are adjacent to the third outer surface 113 to which the wiring board 15 is fixed. On the outer side surface 111, a groove 115 for inserting and holding the first lead wire and the second lead wire electrically connected to the first land 151a and the second land 151b, a lead wire holding portion 116, etc. are formed. ing. Therefore, even if a special part such as a binding band is not used, the ends of the first lead wire and the second lead wire are pulled and the first lead wire and the second lead wire are disconnected. It becomes possible to withstand the first lead wire and the second lead wire against the pulling force.

According to the actuator 1A of the present embodiment, the first lead wire connected to the first land 151a and drawn from the first land 151a and the second lead wire connected to the second land 151b and drawn from the second land 151b are It is inserted into the groove 115 formed on the outer surface of the support body 2 and is held in the groove 115 by the lead wire pressing portion 116. Therefore, even if the movable body 3 moves relative to the support body 2 and causes the support body 2 to vibrate, the lead wire holding portions 116 of the first lead wire and the second lead wire hold the groove 115 in the groove 115. The vibration of the portions causes the stress to concentrate and less likely to be applied to the connecting portions between the first land 151a and the second land 151b at the respective ends of the first lead wire and the second lead wire due to the vibration. .. Therefore, even if the movable body 3 relatively moves with respect to the support body 2 and causes the support body 2 to vibrate, the first land 151a and the second land 151a at each end of the first lead wire and the second lead wire are generated. It becomes difficult for disconnection to occur at each connection portion with 151b, and it becomes possible to withstand the lead wire against pulling force from the outside.

Further, according to the actuator 1A of the present embodiment, the first lead wire and the second lead wire are pulled out to the one side X2 of the second direction X by the first groove 115A, and then the second groove 115B is used for the second direction X. It is bent in one side Z1 of the first direction Z intersecting with and is guided again to one side X2 of the second direction X by the third groove 115C. Therefore, the first lead wire and the second lead wire have the bent portions formed in the grooves 115 formed on the outer surface of the support body 2 and are drawn out of the support body 2. Therefore, even if the first lead wire and the second lead wire are pulled, the pulling force is buffered by the bent portion, and the first land 151a and the second land 151a at each end of the first lead wire and the second lead wire are absorbed. It is difficult for the pulling force to be transmitted to each connection portion with the land 151b. Therefore, the connecting portions of the first land 151a and the second land 151b at the respective ends of the first lead wire and the second lead wire are pulled due to the vibration of the support body 2 and the like. It is possible to make the first lead wire and the second lead wire endure a tensile force from the outside such as the second lead wire being broken.

Further, according to the actuator 1A of the present embodiment, the first lead wire and the second lead wire are held in the second groove 115B by the first holding portion 116A and held in the third groove 115C by the second holding portion 116B. There is. Therefore, the first lead wire and the second lead wire are less likely to come off from the first groove 115A, the second groove 115B, and the third groove 115C formed on the outer surface of the support body 2.

Further, according to the actuator 1A of the present embodiment, the groove width of the third groove 115C is formed smaller than the outer diameters of the first lead wire and the second lead wire. Therefore, the first lead wire and the second lead wire are held while being press-fitted into the third groove 115C, and the tensile force applied to the first lead wire and the second lead wire is the bending portion of the first lead wire and the second lead wire. This pulling force is counteracted by being firmly held in the third groove 115C by press-fitting the first lead wire and the second lead wire into the third groove 115C. For this reason, the connection between the first land 151a and the second land 151b at each end of the first lead wire and the second lead wire is less affected by the pulling force.

Further, according to the actuator 1A of the present embodiment, the first lead wire and the second lead wire have the first width due to the protrusions 203 that are alternately formed on the opposing wall surfaces of the first width groove 115D forming the third groove 115C. It is pulled out while meandering in the groove 115D. Therefore, the tensile force applied to the first lead wire and the second lead wire is buffered by the bent portion of the first lead wire and the second lead wire, and the tensile force is increased due to the meandering of the first lead wire and the second lead wire. It is difficult to reach. Therefore, the connecting portions of the first lead wire and the second lead wire at the end portions of the first land 151a and the second land 151b are pulled, and the lead wire is broken. It becomes possible to withstand the lead wires.

Further, according to the actuator 1A of the present embodiment, in the case where the first lead wire and the second lead wire having different wire diameters are used, the first lead wire and the second lead wire having a large wire diameter and the first outer diameter are , The first lead wire and the second lead wire having the second outer diameter, which are inserted into the first width groove 115D having the first width of the third groove 115C and have the smaller wire diameter, have the second width of the third groove 115C. It is inserted into the second width groove 115E, and is held in the first width groove 115D and the second width groove 115E by the lead wire pressing portion 116B and the standing wall 202. Therefore, even when the first lead wire and the second lead wire having different wire diameters are used, each of the first land 151a and the second land 151b at each end of the first lead wire and the second lead wire is The connection portion is configured to withstand the external pulling force such as the disconnection of the first lead wire and the second lead wire due to the vibration of the support body 2 and the like, and the resistance of the first lead wire and the second lead wire. It becomes possible to do.

Further, according to the actuator 1A of the present embodiment, the second width groove 115E branches from the first width groove 115D to the other side Y2 in the third direction Y from the standing wall 202 standing in the first direction Z, and stands up. Since it is formed side by side with the first width groove 115D in the second direction X via the wall 202, the first width groove 115D and the second width groove 115E having different groove widths are realized in the third groove 115C with a simple structure. it can.

Further, according to the actuator 1A of the present embodiment, the first lead wire or the second lead wire with the first outer diameter having a large wire diameter is drawn out from the first width groove 115D, and the first lead wire with the second outer diameter having a small wire diameter is drawn. The lead wire or the second lead wire is drawn out from the second width groove 115E. Therefore, the height of the first land 151a and the second land 151b formed on the wiring board 15 in the third direction Y and the height of the first lead wire and the second lead wire drawn from the support body 2 in the third direction Y. Are set to different heights. According to such a configuration, the height of the lead-out portions of the first lead wire and the second lead wire, which are loosened by the tensile force applied to the first lead wire and the second lead wire, is formed on the wiring board 15. It is different from the formation height of the land 151a and the second land 151b. Therefore, due to this difference in height, the movable body 3 moves relative to the support body 2 and the vibration generated in the support body 2 and the swaying movement of the lead-out portions of the first lead wire and the second lead wire cause the first land 151a. And it becomes difficult to be transmitted to the second land 151b. Therefore, the movable body 3 relatively moves with respect to the support body 2 and the vibration generated in the support body 2 or the tensile force applied to the first lead wire and the second lead wire causes the movement of the first lead wire and the second lead wire. The influence of each end on the connection between the first land 151a and the second land 151b is reduced. Therefore, the connection between the first land 151a and the second land 151b at each end of the first lead wire and the second lead wire is less likely to be disconnected due to the vibration of the support 2, and Due to the tensile force applied to the lead wire and the second lead wire, it is more difficult to cut or peel off.
