Such a holding body 21 can easily hold not only the drum D having the size as shown in FIGS. 9 and 10 but also other drums D1 and D2 as shown in FIGS. be able to.
That is, FIG. 11 is an explanatory diagram when a drum D1 having a smaller diameter than the drum D shown in FIGS. 4, 9 and 10 is used. In FIG. 11, when the drum D <b> 1 is mounted on the upper arm 26 of the holding body 21, the regulating member is raised on the holding body 21, and when the adjustment unit is moved up on the cylindrical body 22 accordingly, the upper arm 26 The width between the upper arms 26 can be adjusted to the outer circumference of the drum D1 by gradually rotating the distal end portion 26a upward, so that the holding body 21 can reliably hold the small-diameter drum D1.

FIG. 12 is an explanatory view when a drum D2 having a diameter substantially the same as that of the drum D1 and having a slight depth (height) is used.
Also in FIG. 12, when the drum D2 is mounted on the upper arm 26 of the holding body 21, the regulating member 29 is raised on the holding body 21. The tip 26a of the arm 26 gradually rotates upward, and the width between the upper arms 26 can be adjusted to the outer circumference of the drum D2, so that the upper arm 26 reliably holds the drum D2 having a greater depth. be able to.

As described above, in the holding body 21, the width between the upper arms 26 is changed by rotating the upper arm 26 via the lower arm 28 by raising the defining member 29, so that the width according to the diameter of the percussion instrument is changed. Since the configuration is such that the size can be adjusted, the drum can be securely held regardless of the size of the drum diameter. This further enhances versatility for various percussion instruments.
Moreover, since the upper arm 26 is twisted in the middle in the length direction, when the drum D is mounted thereon, it is bent by the weight of the drum D despite being formed of one thin metal plate. Not only is there no danger that the drum D and the detector 35 will be displaced from each other due to the impact when the drum D is hit. Therefore, the holder 21 can hold both the drum D and the detector 35 in a stable state.

  Further, when the regulating member 29 is rotated along the male screw 22a on the cylindrical body 22, the regulating member 29 can move up and down on the cylindrical body 22, and the regulating member 29 can be moved up and down by a simple operation. In addition, since the cylindrical body 22 includes the lock screw 22b for fixing the male screw rod 31 inserted therein, when the male screw rod 31 is inserted into the cylindrical body 22, the lock screw 22b is tightened. Since the male screw rod 31 is securely fixed in a state of being inserted into the cylindrical body 22, even if the male screw rod 31 is attached to the cylindrical body 22 by the fastening members 33 and 34, even if the emergency Since the male screw rod (support) 31 can be prevented from shifting downward or dropping from the cylindrical body 22, there is no danger that the detector 35 shifts with respect to the pad portion P of the drum D. The above reliability can be improved.

In the above-described embodiment, the procedure has been described in which the striking output detector 30 is set in the holding unit 21 when the drum D has not yet been set in the holding unit 21. However, the pad unit P is not provided on the lower surface. Since the practice drum D is used, even if the drum D is set in the holding portion 21 before the impact output detector 30 is set, there is no possibility that the work will be hindered.
