The support arm 30 is formed by bending and extending from the free end of the tilt arm 23 toward the substrate 10, and a contact portion 24 is formed at the bent portion of the support arm 30 and the tilt arm 23. The extension arm 22 is recessed toward the substrate 10.

The support arm 30 includes a main support arm 31 extending vertically from the top of the inclined arm 23 toward the substrate, and a pre-pressing portion 32 bent and extending vertically downward from the rear end of the main support arm 31, wherein both lateral ends of the pre-pressing portion 32 are extended to form pre-pressing end portions 33. The upper surface of the main support arm 31 serves as a suction surface, and the transverse width of the pre-pressing end portion 33 is larger than the transverse width of the main support arm 31 and smaller than the width between the coating portions 40.

The covering portion 40 includes a covering body 41 formed by bending forward from both lateral sides of the substrate 10 and formed on the lateral outer sides of the elastic arm 20 and the support arm 30, and a stopper 42 formed by bending from the front end of the covering body 41 toward the support arm 30. The limiting pieces 42 are pre-pressed in front of the pre-pressing end parts 33, and the transverse width between the pre-pressing end parts 33 is larger than the width between the limiting pieces 42 so as to pre-press the pre-pressing part 32. The lower end of the limiting piece 42 is bent and extended towards the substrate 10 to form a pair of blocking pieces 43, and the blocking pieces 43 are used for blocking the pressing-down of the pre-pressing part 32 when the main supporting arm 31 is pressed down.
