Abstract: A boom tilter includes a tilter body, a boom, a holder, a bolt and nut. The tilter body is attached to a support post to be rotatable around a first axis, which is the axis of the support post. The holder is fitted to the tilter body to be rotatable around a second axis, which is orthogonal to the first axis. The boom is held by the holder to be rotatable around a third axis, which is the axis of the boom, and so that the boom can slide along the third axis.

Abstract: The drum stand includes a stand main body, a drum support, and an attachment that attaches the drum support to the stand main body. The drum support is composed of a first arm and two second arms that open and close with respect to the first arm. The first and second arms all extend obliquely and linearly from near the upper end of a post toward a bottom surface of a snare drum.

Abstract: A spiked leg includes a first leg part and a second leg part, which are leg members, and a stopper fixed to a distal end of the second leg part. The stopper includes a stopper main body, a spike holder, and a spike. In the stopper main body, a part of the stopper main body is located between a first longitudinal hole and a second longitudinal hole. Due to this, the proximal end of the spike is arranged apart from a distal end of the second leg part when the second leg part and the spike are assembled onto the stopper.

Abstract: The drum system has a floor tom, a bass drum, a tom-tom, a snare drum, legs, rods, attachment tools, first and second brackets, and the like. The floor tom is set with a drumhead facing upward, and the bass drum is set with a drumhead facing downward, via the three rods and the first and second brackets. The floor tom is set above the bass drum with a space therebetween via the three rods and the first and second brackets.

Abstract: A tom holder has a holder body, a pivoting member supported pivotably with respect to the holder body, and a rod, which projects from the pivoting member with the tom fixed to the rod. The tom holder has a pair of openings located at opposed positions. The tom holder is configured to be usable in either a first mode, in which the rod projects from the first opening, and a second mode, in which the rod projects from the second opening.

Abstract: A hi-hat bottom supports a bottom cymbal, through which a rod is passed, from below in a state fixed to the upper end of an upper pipe via a retainer. The hi-hat bottom has the retainer, a receiving plate, a compression coil spring, and a lock nut. When a foot plate is depressed, the compression coil spring urges a top cymbal and a bottom cymbal in such a direction that the cymbals contact each other. When the foot plate is not depressed, the bottom cymbal is inclined, together with the receiving plate, at a predetermined inclination angle with respect to a horizontal plane by the urging force of the compression coil spring.

Abstract: A strap for a guitar has a strap belt and two strap connectors each of which is provided at each end of the strap belt. Each strap connector includes a base plate having a first opening, a second opening, and a slit. The first opening has a diameter greater than a head portion of a connector pin. The second opening has a diameter smaller than a neck portion of the connector pin. The slit connects the first and second openings and has a width smaller than the diameter of a neck portion of the connector pin. In the strap connector, a portion of the base plate adjacent to the slit is bendable.
