<P>PROBLEM TO BE SOLVED: To easily mount a pedal without using a screw or the like, in a pedal unit of an electronic musical instrument, etc. <P>SOLUTION: The pedal 50 of the pedal unit is formed in an approximately "U" shape in a cross section. In Fig.2(d), a through-hole 52 is formed in the top plate of a rear end 50a of the pedal. In Fig.2(f), a nearly "H"-shaped through-hole 48 is formed on a frame back plate 40a. Thereby a projecting part 48a is formed. When the pedal 50 is turned in a way such that it is slightly twisted with a longitudinal direction as an axis, the pedal rear end 50a is inserted into the through-hole 48. When the through-hole 52 and the projecting part 48a are fitted in a position where both face each other, the pedal 50 is leveled as shown in Fig.2(e). Thereafter, when a guide block 36 is mounted on the pedal 50 as shown in Fig.2(a), the pedal 50 does not turn with the longitudinal direction as the axis and accordingly, the pedal rear end 50a is not disengaged from the frame back face plate 40a. <P>COPYRIGHT: (C)2009,JPO&INPIT |
