Abstract

PURPOSE:To make the pawl of a front panel securely contact an earth electrode by forming the contacting surface of the pawl which contacts the earth electrode in a saw-tooth shape. CONSTITUTION:The pawl 4a of the front panel 4 is engaged with a printed board 2 to fix a liquid crystal element to the printed board 2, and the pawl 4a of the front panel 4 is brought into contact with the earth electrode 5 of the printed board 2. Here, the contacting surface of the pawl 4a which contacts the ground electrode 5 is formed in the saw-tooth shape 4b. Consequently, when the pawl 4a is engaged with the printed board 2, peak parts of the saw-tooth wave shape 4b intrude into the earth electrode 5 and the pawl 4a securely contacts the earth electrode 5.

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. Note that the same or equivalent members as in FIG. 3 are given the same numbers, and their explanations will be omitted. The contact surface of the claw 4a of the front panel 4 with the ground electrode 5 is serrated 4b.
