As shown therein, an intermediate connection plate 12 is connected at a front end of a wearing plate 10 using a pin 11, with the wearing plate 10 being worn on an upper arm of a wrist using a band. The intermediate connection plate 12 can rotate in left and right direction with respect to the wearing plate 10 around the pin 11. A hand back support plate 13 is connected at both ends of the intermediate connection plate 12 using a pin 14, with the hand back support plate 13 being adapted to support a hand back. The hand back support plate 13 can rotate in upper and lower vertical directions and in left and right horizontal directions with respect to the wearing plate 10 and the intermediate connection plate 12. A guide groove 21 and a buttonhole 22 are integrally formed at a housing 10, which is connected at an upper surface of the intermediate connection plate 12 using a bolt. Vertical guide grooves 23 and 23'are formed at the intermediate portions of both wall surfaces of the inner space of the housing 20. An adjusting part 26 includes upward engaging teeth 25 and 25' at the left and right sides of the intermediate portion with respect to a button rod 24 provided at an upper side. A rack 30 includes downward engaging teeth 28 and 28' at both sides of a groove 27, and a guide protrusion 29 formed at an upper surface of the front end side. The adjusting part 26 and the rack 30 are provided in the interior of the housing 10 so that the button rod 24 is inserted into the button hole 22 of the housing 20, the guide protrusion 29 is inserted into the guide groove 21, the both ends of the upward engaging teeth 25 and 25' of the adjusting member 26 are guided by the vertical guide grooves 23 and 23' in a state that the adjusting part 26 is inserted into the groove 27 of the downward engaging teeth 28 and 28'. A spring 32 inserted onto a rod 31, which connects an inner back surface of the housing 10, is inserted into the hole 33 formed at a rear side of the rack 30, so that the rack 30 is elastically pushed to the outside of the housing 10 by the force of the spring 32. A fixing plate 35 is installed at a lower surface of the adjusting part 26 using a bolt, with a lever 34 and a through hole 35' being provided at an upper surface of the intermediate connection plate 12. Seven lock holes 36 are formed at the engaging plate 10 with an arrangement formed in a radius direction with respect to the pin 11. Here, the number of the lock holes 36 is not limited to seven. In addition, one pin hole 37 matching with each lock hole 36 is formed at the intermediate connection plate 12, so that a lower end of the lock pin 38 is inserted into the lock hole 36 through the through hole 35' formed at the fixing plate 35 and the pin hole 37. A head part 38' of the lock pin 38 is inserted and engaged into a groove 41 formed at one side of a seesaw member 40 and is placed on the lever part 34 of the fixing plate 35 by inserting the protrusion 42 of the seesaw member 40 into the engaging groove 26' formed at the adjusting member 26. A spring 43 is installed between the lower end of the adjusting member 26 and the upper surface of the intermediate connection plate 12, so that the adjusting member 26 is upwardly supported with an elastic force of the spring 43.

A button 45 is connected at an upper end of the button rod 24 of an adjusting member 26 externally exposed through the button hole 22 using a bolt. The operation of the present invention will be described. In a state that a bowling game player wears the apparatus using a band connected with the wearing plate 10, the adjusting part 26 moves down by pressing the button 45. The upward engaging teeth 25 and 25' are separated from the downward engaging teeth 28 and 28' and the rack 30 is escaped from the locking state of the adjusting member 26 and is moved outwardly, with the rack 30 being prevented from its escape by contacting with the protrusion 13' of the hand back support plate 13. At this time, the protrusion 42 of the seesaw member 40 is pressed by the engaging groove 26' so that the seesaw member 40 supported by the lever part 24 is tilted, whereby the lock pin 38 rises. The lower end of the lock pin 38 inserted into the lock hole 36 is moved up to the pin hole 37 of the intermediate connection plate 12, so that the intermediate connection plate 12 can move leftwards and rightwards with respect to the wearing plate 10. In this state, the position of the rack 30 is set by the protrusion 13' of the hand back support plate 13 in such a manner that the vertical and horizontal angles are adjusted so that the user can release a ball with a proper wrist power. Therefore, the vertical angle is adjusted. The intermediate connection plate 12 rotating with respect to the pin 11 is placed at a position corresponding to the adjusted horizontal angle, so that the lock pin 38 is placed at the position of the lock hole 36 corresponding to the adjusted horizontal angle. In this state, when the pressed button 45 is released, the adjusting member 26 returns to the original position by an elastic force of the spring 43, and the upward engaging teeth 25 and 25' are engaged by the downward engaging teeth 28 and 28' and the rack 30 is limited by the adjusting member 26. With this operation, the hand back support plate 13 is fixed at the adjusted vertical angle, and the seesaw member 40 is released from the adjusting member 25, so that the lock pin 38 raised by the spring 44 moves downwards. The seesaw member 40 returns to its original position. The lower end of the lock pin 38 is inserted into the lock hole 36 corresponding to the adjusted horizontal angle, and the horizontal angle of the hand back support plate 13 is fixed at the adjusted angle. Therefore, the vertical and horizontal angles of the hand back support plate 13 needed for the ball releasing operation can be adjusted by one operation of the button 45.
