The grip portion 3 has an upper end portion 3B and a lower end portion 3C butted together, a nut 5 is accommodated in the upper end portion 3B, and a head of a bolt (not shown) is brought into contact with the lower end portion 3C. In this state, the grip portion 3 is fixed to the handle by screwing the screw portion of the bolt into the nut 5 and tightening it. A bell support portion 3D projects from an upper end 3A of the grip portion 3, and a cup-shaped bell 6 is press-fitted and fixed to the bell support portion 3D with an opening facing upward. A diametrically expanded portion 4A having a larger diameter than this is connected to the head of the shaft portion 4, and a support shaft 4B extending downward to one side (left side) in the radial direction of the diametrically expanded portion 4A.
And a protrusion 4C extending downward on one side (right side) in the radial direction.

A striking means 9 for ringing the bell 6 is provided on the shaft portion 4, and the striking means 9 is provided with an operating member 10 and a striking member 11 rotatably provided on the shaft portion 4.
It has and. The shaft portion 4 is formed by fitting the grooved engagement portion 4D at the lower end of the shaft portion 4 into the grooved hole 3E of the grip portion 3 in a state where the operation member 10 and the striking member 11 are penetrated. 4 is connected so as not to rotate. The striking member 11 includes a pair of upper and lower three arms 11B extending outward in the radial direction from circumferentially trisecting positions on the outer periphery of the lower end of the tubular portion 11A penetrating the shaft portion 4, and the tubular portion. The gear 13 is formed on the outer periphery of the upper end of the shaped portion 11A. Of the pair of arms 11B, an engaging protrusion 11C protruding downward is formed at the tip of the upper arm 11B,
The engagement protrusion 11C is loosely fitted in the ring-shaped hammer 14. As a result, the striking member 14 can be projected and retracted in the radial direction around the tubular portion 11A only by the gap between the inner diameter and the engagement protrusion 11C. Further, the bell 6 is formed in a cup shape so as to accommodate the striking member 11, and the bell 6 is press-fitted into a ring-shaped groove formed on the outer peripheral surface of the bell support 3D. 6A, a taper portion 6B that expands upward from the lower end of the press-fitting portion 6A, and a tubular portion 6C that extends upward from the upper end of the taper portion 6B in parallel with the shaft portion 4. The inner diameter of the cylindrical portion 6C facing the striking member 14 is set to a size that does not contact the striking member 14 even when the striking member 14 projects outward in the radial direction around the shaft portion 4. is there. A projection 6C 'that projects radially inward is formed on one side (left side) in the radial direction of the cylindrical portion 6C, and the hammer 14 that projects radially outward is the projection 6C.
It is possible to hit the bell 6 by striking it and the hammer 14 can pass through the front surface of the projection 6C 'while receding in the radial direction by the collision.

Next, the operating member 10 is penetrated through the shaft portion 4 and has a recessed portion for accommodating the expanded diameter portion 4A of the shaft portion 4 in the center thereof and is formed to have a diameter larger than that of the bell 6. A disc-shaped cover portion 10A, a side wall portion 10B extending downward from the outer peripheral portion of the cover portion 10A and overlapping with the cylindrical portion 6C of the bell 6, and the side wall portion 10B.
And a lever portion 10C that projects radially outward from one side (left side) in the radial direction, and has a circular arc shape that penetrates the pinion support shaft 4B and the protruding portion 4C at a predetermined position of the recess. Openings 10D and 10E are formed.
As a result, the operating member 10 can be horizontally reciprocally rocked about the shaft portion 4 within a predetermined range. The operation member 10 is normally urged counterclockwise by a return spring 15 mounted between the operation member 10 itself and the enlarged diameter portion 4A of the shaft portion 4 and locked to the protrusion 4C. As a result, if an operating force is applied in the clockwise direction by pulling or pushing the operating member 10 from the inoperative state, the operating member 10 can be rotated in the clockwise direction against the elastic force of the return spring 15. When the operating force is released, the elastic force of the return spring 15 can return the operating member 10 to the inoperative position in the drawing. The return spring 15 has a helically wound coil portion which is penetrated by and held by the protrusion 4C, and one end of which is brought into contact with a spring receiver 4E formed in the diameter-expanded portion 4A, while the other end of which is held. The portion is brought into contact with a spring receiver 10F formed on the operation member 10.

The support shaft 4B has a large gear 20A located below.
