性に問題点を有する。In a conventional solar-powered timepiece, a solar cell that receives light to generate electricity is arranged under a pointer and a dial for displaying time, and usually has a plane area substantially the same as that of a dial for design decoration. Therefore, the dial plate is required to have a property of transmitting light, which limits the material of the dial plate and limits the freedom of design such as the color tone of the dial plate. And as a solar power generation timepiece that solves this problem, instead of arranging the solar cell on the dial, it is placed on the inner periphery of the side body perpendicular to the dial and receives light, so a dial that does not require light transmission performance is used. A ring solar timepiece that can be used has been devised and put into practical use, but this type of solar power generation timepiece has a problem in the assemblability of its solar cell.

ａの部分へ設けられている。In the state where the solar cell 12 and the movement support base 11 of FIG. 1 are assembled, the solar cell 12 which is assembled in a rolled state works by the force of returning to the original natural shape, and the assembled state is released. A phenomenon occurs in which the solar cell 1 moves in the direction of the arrow in FIG.
The second hooking hole 12c is hooked on the hook portion 11d of the movement supporting base 11, and the solar cell 12 is further moved in the direction of the arrow and cannot be detached from the movement supporting base 11. Since the solar cell 12 is firmly attached to the solar cell wall surface portion 11a of the movement support base 11, the hook portion 11d of the movement support base 11 is attached to the solar cell wall surface portion 11a.
It is provided to the portion a.

る。Next, a second embodiment of the present invention will be described with reference to FIG. The present embodiment is characterized in that the bank portion 11c is formed at an acute angle with respect to the clock face. Since outside light such as sunlight enters the clock from the upper side of the figure,
If the bank portion 11c is configured as in this embodiment, the solar cell 12 is likely to receive light and the amount of power generation can be increased. However, since the solar cell 12 easily moves in the direction of the arrow in the drawing, the workability of assembling the solar cell 12 is further deteriorated, but there is no problem because the movement is restricted by the hook portion 11d. Solar cell 1 as above
The present invention is particularly effective in the case of this embodiment in which the bank portion 11c is provided with a slope in order to increase the power generation amount of No. 2.
