Material), and a large number of protrusions 10a can be formed on the outer peripheral surface thereof. The protruding portion 10a has a wall shape formed in the left-right short direction (height of about 2 mm), and is provided with a predetermined interval (for a plurality of pachinko balls) in the front-rear longitudinal direction.

  The protrusion 10 a abuts on the upper part of the pachinko ball 4 on the upper surface of the replenishing rod 20 by the movement of the conveyor belt 10, and acts as a speed imparting member that imparts a speed in the moving direction to the pachinko ball 4.

  Further, as shown in FIGS. 8 and 9, the conveyor belt 10 has, for example, hemispherical protrusions 10a having a radius of about 2 mm on the outer peripheral surface at equal intervals in the left-right short direction (for one to two pachinko balls). A hemispherical row 10L is provided, and a large number of hemispherical rows 10L are arranged at equal intervals (for a plurality of pachinko balls) in the longitudinal direction. In addition, the protrusions 10a of each hemisphere array 10L are provided so as to be shifted obliquely in the horizontal direction from the corresponding protrusions 10a of the front and rear sphere arrays 10L, and are arranged in a so-called zigzag pattern. This protrusion 10 a also abuts on the upper part of the pachinko ball 4 on the upper surface of the replenishing rod 20 by the movement of the conveyor belt 10 and acts as a speed imparting member that imparts a speed in the moving direction to the pachinko ball 4.

  In addition, since the protrusion part 10a is hemispherical and is arrange | positioned with the space | interval larger than the pachinko ball, the pachinko ball 4 can pass between these protrusion parts 10a easily. Therefore, the situation where the pachinko ball 4 is clogged can be avoided in advance. Moreover, since the protrusion part 10a is arrange | positioned in zigzag form, the subsequent protrusion part 10a contact | abuts to the pachinko ball 4 which passes between the protrusion parts 10a and has remained there. Therefore, all the pachinko balls 4 can be smoothly conveyed.
