A rotary manipulating apparatus of a rotary type of which the action can be conducted with a definite sense of use is provided for, when installed in an electric or electronic instrument, simplifying the packaging of the electric or electronic instrument with packaging materials shaped and arranged not intricate and minimizing the damage in case that the instrument in the packaging suffers from any accidental collision during delivery. The rotary manipulating apparatus includes a base 3 for mounting to the instrument, a manipulating means 4 for carrying out a rotating action, and a movable means 5 provided between the base 3 and the manipulating means 4 for slidably moving the manipulating means 4 or an input rotary shaft 6 for actuating the manipulating means 4 along the axial direction in relation to the base 3.

A counter-force mechanism (37), which produces a counter force when a brake booster is operated, is made up of an input-side member (38) slidably disposed within a valve body (3), a second constant-pressure chamber (39) formed on the rear side of the input-side member and into which a pressure is introduced from a constant pressure chamber (A), and a second constant-pressure chamber (39) formed on the front side of the input-side member and into which a pressure is introduced from a variable pressure chamber (B). The counter force from the counter-force mechanism (37) is reduced by an orifice passage (43) as a counter-force reducing means in rapid operation of the brake.

In a brake-pressure producing device of the present invention, a power piston 10 of a hydraulic booster 2 comprises a stepped piston including a large-diameter portion 10a on which fluid pressure of a power chamber 30 is exerted and a small-diameter portion 10b having the same diameter as the master cylinder piston 53. Both the pistons 10, 53 are interlocked with each other through an aligning rod 62. The pressurized fluid of the power chamber 30 is introduced into an annular chamber 51 formed on the circumference of the small-diameter portion 10b and the fluid pressure of the pressurized fluid is exerted on a stepped portion 10c between the large-diameter portion 10a and the small-diameter portion 10b in the direction opposite to the direction of the fluid pressure of the power chamber 30. When the braking operation is performed, the fluid pressure in the power chamber 30 introduced into wheel cylinders 33, 34 relating to one of the circuits and the master cylinder pressure introduced into wheel cylinders 58, 59 relating to the other circuit balance to be equal to each other, thereby uniformly and properly distributing braking forces to the respective wheel cylinders.

A drum stand includes a center pipe, a fixed collar, a first movable collar, a second movable collar, legs, and stays. The fixed collar is secured to the lower end of the center pipe. The first movable collar and the second movable collar are slidably fitted to the center pipe. Legs of a first type are pivotally coupled to the first movable collar. A leg of a second type is pivotally coupled to the second movable collar. Stays of a first type are pivotally coupled to the second movable collar. A stay of a second type is pivotally coupled to the fixed collar.

A carrier for holding a bass drum with two first connection mechanisms and one second connection mechanism. The second connection mechanism includes a connection member, which is arranged on the bass drum, and a slide member, which is arranged on the carrier. The distal end of the slide member is engaged with the connection member. Each first connection mechanism includes a hook receptacle, which is arranged on the bass drum and open in a downward direction, and a hook, which is arranged on the carrier and inserted in the receptacle.

In a fluid pressure boosting device 1 of the present invention, a control valve 4 is composed of a supply valve 44 and a discharge valve 45, the supply valve 44 comprises an annular valve cone 46 of a poppet type and a first valve seat 7 and the discharge valve 45 comprises an annular valve cone 46 of a poppet type and a second valve seat 8. Inside a rear end portion of a primary piston 21 of a master cylinder 2, a reaction disk 57 made of an elastic material such as rubber is fitted. An input shaft 3 penetrating the control valve is arranged such that, in the inoperative state, an end thereof confronts the reaction disk 57 with a predetermined space therebetween and, in the operative state, the end comes in contact with said reaction disk 57 so that a reaction force is transmitted to the input shaft 3. The passage for discharging hydraulic fluid of the power chamber 9 is composed of annular passages 52, 53. Therefore, a fluid pressure boosting device of a center valve type can be provided of which the structure for attaining the jumping characteristic and the structure of passage for discharging hydraulic fluid are simple.
