PROBLEM TO BE SOLVED: To improve workability for changing the installation angle of a telephone system main body via a base and also to reduce possibility of breakage of an attachment elastic pawl by preparing a space at the pawl part of the base, where a finger of a user can be inserted and enabling the user to press and deform the elastic pawl with his finger. SOLUTION: When a base 2 is removed from a telephone system main body 3 by changing the installing angle of the body 1, a user inserts his/her finger into a space 14 from the rear side at the part of an elastic pawl 7 of the base 2 and then presses the pawl 7 towards an arrow 15, where the pawl 7 is removed from the wall surface of a hooking hole 8 to cause the pawl 7 to deform. Thus, the pawl 7 is removed from the hole 8. Then a fixed pawl 4 is pulled out of a fixed pawl hooking hole 5. In such a constitution, the user can insert his finger into the space 14 of the elastic pawl part of the base 2 from the rear side and then presses the pawl 7 in the direction where the pawl 7 is removed from the hole 8 to cause the pawl 7 to deform. Thus, the base 2 can be removed easily form the body 3.
