An object of the present invention is to provide fin in which the fin can be easily attached or detached to a board, its attached state can be maintained well, and the fin readily comes off in an emergency such as when the fin is brought into contact with human body. Furthermore, it is an object of the present invention to allow the reduction of rattle when the fin is attached. To solve such problems, provided is a fin, comprising a hollow part at a side surface of an attachment base portion of the fin to be attached to a groove in a bottom surface of a surfboard, wherein a ball part is biased outwardly of the hollow part by an elastic member in the hollow part; and wherein the ball part in the hollow part of the attachment base portion of the fin is moved into the hollow part against a biasing force from the elastic member, and thus the fin is detachably mounted in the attachment groove of this board under elastic compression force.

1. A fin to be attached to a fin attachment groove formed in a bottom surface of a surfboard, the fin comprising: an attachment base portion sized and configured to be received within the fin attachment groove in the bottom surface of the surfboard;a plurality of hollow parts formed within at least one side surface of the attachment base portion of the fin,at least one plunger positioned within a first respective one of the hollow parts, the plunger comprising a ball part and an elastic member which biases the ball part outwardly of the hollow part for engagement with a first corresponding opposed surface portion of the groove when the attachment base portion is received therein so as to provide detachable mounting of the fin to the surfboard; andat least one non-slip member positioned within a second respective one of the hollow parts, the non-slip member comprising a main body portion sized and configured to be received within the hollow part, and a non-slip part at an exposed end face of the main body portion, wherein the non-slip part protrudes outwardly from the hollow part so to be sandwiched between the attachment base portion and the groove, the non-slip part being engaged with a second corresponding opposed surface portion of the groove when the attachment base portion is received therein, wherein the non-slip member is formed of a resin material providing frictional resistance with the second corresponding opposed surface portion of the groove against which the non-slip member is engaged so as to prevent fin rattling when the attachment base portion is detachably mounted to the fin attachment groove of the surfboard. 2. The fin according to claim 1, which includes an engaging part for engaging with a fastener in the fin attachment groove of the surfboard at one end of the attachment base portion 1 of the fin; and wherein at least one of the hollow parts and a corresponding plunger are provided at an opposite end of the attachment base portion of the fin and at a side surface of the attachment base portion. 3. The fin according to claim 1, wherein the hollow parts and a corresponding plunger are provided on both sides of the attachment base portion of the fin. 4. The fin according to claim 1, wherein the hollow parts and a corresponding plunger are provided at least at two or more positions at one side surface of the attachment base portion of the fin. 5. The fin according to claim 1, wherein selected ones of the hollow parts extend through the attachment base portion of the fin so as to be exposed at both side surfaces thereof, and wherein each of the selected ones of the hollow parts includes a plunger having an elastic member and a pair of ball parts which are biased outwardly of the hollow part in both end directions thereof. 6. The fin according to claim 1, wherein plunger is mounted detachably in the hollow part of the attachment base portion of the fin. 7. The fin according to claim 1, wherein the elastic member is a coil spring. 8. The fin according to claim 1, wherein at least a part of the ball part is a spherical body. 9. The fin according to claim 1, wherein the attachment base portion of the fin has a length which is smaller than a length of the fin attachment groove of the surfboard. 10. The fin according to claim 1, wherein the non-slip member is detachably mounted to a hollow part. 11. The fin according to claim 1, wherein one side surface of the fin includes a hollow part in which a respective non-slip member is mounted. 12. The fin according to claim 1, wherein both side surfaces of the fin include a hollow part in which a respective non-slip member is mounted. 13. The fin according to claim 1, wherein the hollow part in which the non-slip member is mounted is provided at two or more positions in the attachment base portion of the fin. 14. The fin according to claim 1, wherein at least one of the hollow parts extends through the attachment base portion of the fin so as to be exposed at both side surfaces thereof, and wherein the non-slip member includes a main body portion positioned within the at least one of the hollow parts, and non-slip parts at opposed end faces thereof. 15. The fin according to claim 1, which comprises a plurality of plungers and a plurality of non-slip members, and wherein the plurality of hollow parts is located at least at two or more positions in a side surface of the attachment base portion of the fin, and wherein each of the hollow parts of a first set thereof includes respective one of the plungers, and wherein each of the hollow parts of a second set thereof includes a respective one of the non-slip members, and wherein the plungers and non-slip members are detachably mounted within the hollow parts. 16. The fin according to claim 1, wherein resin material of the non-slip part at the exposed face of the non-slip member has an irregular shape. 17. The fin according to claim 1, wherein resin material of the non-slip part at the exposed face is an adhesive material. 18. The fin according to claim 1, wherein resin material of the non-slip part at the exposed face is an elastic material.
