    • Provided is a tilt foot mechanism of a projection display device, in which the number of components is reduced to lower costs. The tilt foot mechanism includes foot (14) elevatable with respect to the case of the projection display device. Foot (14) includes rod (20) in which spiral groove (23) is formed. The tilt foot mechanism further includes base portion (11) integrally formed with the case, lever (12) rotatably attached to base portion (11) and having convex portion (42) formed to fit in groove (23) of rod (20), and spring (13) disposed between base portion (11) and lever (12). Lever (12) has projection (45) on which a part of foot (14) can abut. Lever (12) is rotated against the pressing of spring (13) along with the rising of foot (14) abutted on projection (45).
    • 提供了一种投影显示装置的倾斜脚架机构,其中部件的数量被减少以降低成本。 倾斜脚机构包括相对于投影显示装置的壳体可升高的脚部(14)。 脚部(14)包括形成有螺旋槽(23)的杆(20)。 倾斜脚部机构还包括与壳体一体形成的基部(11),可旋转地附接到基部(11)并且具有形成为装配在杆(20)的凹槽(23)中的凸部)的杆(12) 以及设置在基部(11)和杠杆(12)之间的弹簧(13)。 杠杆(12)具有突起(45),脚部(14)的一部分可抵靠在其上。 杠杆(12)随着与突起(45)抵接的脚(14)的上升一起抵抗弹簧(13)的按压而旋转。
