At this time, the hook portions 40, 40 are engaged against the elasticity of the locking pieces 41b, 41b, and after the engagement, the terminal box 21 is firmly fixed. In addition, since each of the locking pieces 41b is provided so as not to touch the wiring board 29 when the hook-shaped portion 40 is located rearward of the wiring board 29 and is bent, when the terminal box 21 is attached, In addition, each of the locking pieces 41b does not touch the wiring board 29, so that it is possible to prevent the wiring board 29 from being bent or damaged. The wiring board 29 disposed inside is pressed at the four corners by the support cylinders 43, 43, and is firmly fixed without rattling.
[0014]
Further, to remove the terminal box 21, the locking pieces 41b, 41b of the upper side frame 27b are pressed against their elasticity, and the hook-shaped portions 40, 40 are removed from the engagement holes 44, 44. Subsequently, the hook portions 40, 40 are extracted from the respective engagement holes 44, 44 of the lower side frame 27a. As described above, the locking pieces 41a and 41b are provided, and the hook-shaped portion 40 at the tip thereof is engaged with the engaging hole 44. Therefore, when engaging, the locking pieces 41b and 41b of the upper side frame 27b are moved. It is elastically bent, and the hook-shaped portion 40 can be easily engaged, so that the work of attaching and detaching the terminal box 21 can be easily performed.
[0015]
FIG. 5 shows that notches 55, 55 are provided at the bases of the locking pieces 41b, 41b of the upper side frame 27b in the terminal box 21, and the engaging holes 44, 44 are formed in the upper surrounding frame 42b on the mechanism plate 6 side. The terminal box 21 can be easily attached to or detached from the mechanism plate 6 in the same manner as described above even if such means are employed.
[0016]
6 and 7 show the mounting structure of the terminal box 20 mounted on the lower part of the mechanism plate 6. FIG. The terminal box 20 also comprises a cover body 28 'made of a synthetic resin with the rear surface opened by surrounding the front plate 25' with a side frame 27 ', and a wiring board 29' is arranged in the cover body 28 '. . On the wiring board 29 ', the accessory power supply terminal 47, the speaker terminal 48, the ball cutting motor terminal 49, etc., which are exposed to the outside through the openings 30', 30 '. 50 are provided respectively. Reference numeral 51 denotes a connection terminal for connecting a wiring to the terminal box 21 via the connector 22.
[0017]
On the outer surface of the right frame 27'a, a locking piece 52a provided with a hook-like portion 40 at the end substantially in the center is integrally extended, and on the outer surface of the left frame 27'b, both ends are provided with a tip. Two locking pieces 52b, 52b provided with hook-shaped parts 40, 40 are integrally extended. Further, a flat plate portion 53 having substantially the same size as the terminal box 20 is formed on the mechanism plate 6, and the wiring board 29 'in the terminal box 20 is pressed and fixed to the four corners of the flat plate portion 53 in the same manner as described above. The support cylinders 54, 54 ... are protruded. An engagement hole 44 is formed on the right side of the flat plate portion 53 at a position corresponding to the locking piece 52a, and two engagement holes are formed on the left side at a position corresponding to the locking pieces 52b, 52b. Holes 44, 44 are opened.
[0018]
First, the hooks 40, 40 at the tips of the locking pieces 52b, 52b are engaged with the left engagement holes 44, 44, and then the locking pieces 52a are pushed into the right engagement holes 44 to engage. Let it. Also, when removing, the hook-shaped portion 40 is pulled out from the holding engagement hole 44 against the right engaging piece 52a against its elasticity, and subsequently, the hook-shaped portion 40, Pull out 40. Also in this case, the terminal box 20 can be easily attached and removed in the same manner as described above.
[0019]
Also in this case, as shown in FIG. 7, each of the locking pieces 52a and 52b does not touch the wiring board 29 'when its hook-shaped portion 40 is located behind the wiring board 29' and is bent. That is, the locking pieces 52a, 52b are provided outside the side frames 27'a, 27'b, and are provided on the side frames 27'a, 27'b behind the wiring board 29 '. When the terminal box 20 is mounted, the locking pieces 52a and 52b do not touch the wiring board 29 ', and thus the wiring board 29' is bent. Damage can be prevented. Further, each of the locking pieces 52a, 52b provided with the hook-shaped portion 40 is disposed outside the outer surface of the side frames 27'a, 27'b, and the hook-shaped portion 40 is provided with the side frames 27'a, 27'b. Because it is located behind the trailing edge, for example, when shipping as a product from a factory, volume reduction means is used to increase transportation efficiency, but for this purpose, products are easily superimposed, and hook-like It is less likely that the part 40 is damaged.
[0020]
