Since it supports in the state made into the state, it can prevent that an excessive load and a bending moment act on this stopper axis | shaft 28c, and are damaged. Therefore, it is possible to use the rotation stopper member 29 having a versatility applicable to various commodity storage passages 13 and having a small width dimension, and the rotation stopper member 29 can be shared. Therefore, it is possible to prevent the stopper shaft 28c of the rotation stopper member 29 from being damaged and reduce the manufacturing cost.

  Further, the shaft abutting portion 33 provided on the base member 21 makes it possible to shorten the length of each of the first swing support shaft 24a and the second swing support shaft 25a. The lengths of the dynamic support shaft 24a and the second swing support shaft 25a can be reduced to the minimum necessary length, and the material cost required for the first swing support shaft 24a and the second swing support shaft 25a is reduced. It becomes possible to make it. Further, the bearing piece 23 is provided with a cylindrical bearing portion 232 in a form communicating with a hole 231 (a hole through which each of the first swing support shaft 24a and the second swing support shaft 25a passes) 231. Even if the thickness of the base member 21 is reduced, the first swing support shaft 24a and the second swing support shaft 25a can be favorably supported.

  According to the commodity dispensing device 20, the fixing piece 31 that fixes the solenoid 40 is cut and raised in such a manner that the base portion 311 continuous with the base member 21 is parallel to the driving direction of the solenoid 40 (the movement direction of the plunger 43). Therefore, even when the thickness of the base member 21 is reduced, the base member 21 has sufficient strength, and there is no possibility that the root portion 311 deteriorates with time and is damaged. Therefore, the solenoid 40 can be favorably supported while reducing the manufacturing cost. In particular, a diaphragm structure for forming the curved portion 311a is provided at both end portions of the root portion 311 and an arc-shaped notch 311b is formed in the curved portion 311a, thereby eliminating a portion where stress is concentrated by driving the solenoid 40. Accordingly, the solenoid 40 can be favorably supported. Further, since the solenoid 40 can be locked by the locking piece 34 provided on the base member 21, the solenoid 40 can be easily positioned and can be assembled without requiring a jig or the like. .

  According to the commodity dispensing device 20, the engagement claw 27 a of the link member 27 that is inserted into the engagement hole 43 a of the plunger 43 that reciprocates by the solenoid 40 and engages with the plunger 43 is formed at the upper end of the link member 27. Is formed by being bent toward the opposite side of the product storage passage 13, it becomes possible to assemble the solenoid 40 after attaching the link member 27 during the assembly work of the product delivery device 20. The adverse effect of attaching the link member after attaching the solenoid as in the prior art can be eliminated, and the respective constituent members can be assembled independently. Therefore, the assembly work can be facilitated.
