A handle portion of the housing has a left push button () and a right push button () inserted therein, a first groove () and a second groove () of the left push button () and right push button () each having a second engagement portion formed on a groove wall thereof, each of a first extension section (-) and second extension sections (-) being provided with, at a side facing a corresponding second engagement portion, a third engagement portion engageable with the corresponding second engagement portion.
